Halo: The Master Chief Collection

HaloMCCWTBanner

Hello and welcome to the TrueAchievements walkthrough and achievement guide for Halo: The Master Chief Collection. As this is my largest undertaking to date, I ask that you bear with me and if there are grammatical mistakes or misplaced information that make it through the review process, please point them out to me so I can make corrections.

Better put your big girl panties on for this one folks, because tackling 700 achievements for 7000 Gamerscore, not to mention undertaking the Legendary speed runs and LASO challenge for the last few, is going to be a bigger bite that most are used to, even the most die-hard Halo fans

There will be a separate page for achievements that are across multiple titles. LASO guides will simply be a link to a Youtube video playlist, each by a different Youtuber. I will not, however, be adding a written text guide for LASO. Most people will be tackling one or two levels at a time when it comes to LASO, probably in co-op, and those videos will do far more to assist you in tackling LASO than any text guide could ever hope to accomplish.

Within each game's section (other than Halo 2) we start off with the campaign walkthrough, followed by miscellaneous/mop up. Halo 2's miscellaneous achievements have their own page, as there are so many of them. Several of the cross-title cumulative kill total achievements may come along the way while you play, but they will be more fully detailed on the cumulative/cross-title page.

I've ball parked the completion at between 250 and 300 hours because the 500 MP wins can be boosted by yourself in a customs lobby. The majority of the game's achievements can probably be done in under 100-150 hours, but depending on your skill level (and your partner if LASO and speed runs are done co-op) the LASO and Legendary Campaign speed run achievements could add 100+ hours.... or even longer..... Ouch. No matter how you slice it though, it's a long one.

Let's hit it Marines!

This page will serve a two-fold purpose. The first is to serve as a warning. Unlike previous Halo titles (Halo: CEA specifically), this collection does not allow you to use 'easy mode' skulls and gain CERTAIN achievements. So for those of you thinking of running through CE and 2 with the Bandana skull, or Halo 2 with the Scarab skull, to get those Legendary Speedrun achievements, think again.

Certain skulls disable Par Time and Par Score, as well as Legendary Speedruns and Leaderboardss. Any skull with a 0.00x multiplier does this (think Scarab, Bandana, Envy). However, these skulls can still be used to get collectibles, level specific achievements (like not killing any Grunts on an entire level in Halo CE), and most importantly Easter Eggs! Megg and Return to Megg are much easier now. Also, due to a patch changing it (perhaps unintentionally), you can get the level-completion and campaign-completion (including Legendary completion, just not the speedrun) with these 'easy mode' skulls. If the achievements don't unlock right away, back out to the main menu, then go back into the campaign menu for that game to unlock them. This has reported to be spotty, but don't sweat the level and campaign completion achievements. You'll get them while going for Par Time, Par Score, or Legendary Speed Runs anway.


A Note About LASO


I won't be writing a step-by-step guide for the LASO playthroughs. It would be mind bogglingly cumbersome, and to be honest a lot of the LASO runs rely on good old RNG to get past certain portions. My best advice is to follow along with the videos inch by inch, mile by mile. Co-op can make some of these, particularly Halo 3 and 4, immensely easier. Speed run tricks like the bridge drop despawn in AOTCR in Halo CE and the pressure launch/god launch in The Oracle in Halo 2 will also help, and such tricks have been described within those specific levels. I have removed the individual LASO videos because if you're going to go through each and every level LASO, you may as well just go to the playlist and follow along, since each level may take hours, or longer.


While TECHNICALLY there is still a semi-workaround to have someone pop the achievements for you, which can be found in HERE, it is hit or miss and may not work for you. Also, if you visit that thread in the hopes to get the LASO achievements, READ THE RULES. Don't post in the thread asking for help. Look for replies to the thread about help sessions that have been created and join those, or just search for sessions. Again, DO NOT ASK FOR HELP IN THE THREAD, as it will likely be ignored. Look for sessions to join. Either way, there's a good chance, now that the checkpoint sharing has been patched, that you will have to slog through each full game on LASO (co-op preferably, of course). This is totally doable in CE, 3, ODST, and 4. Good luck getting through Gravemind LASO on Halo 2, though, even co-op. Pingy's and videos should help for H2 LASO, but they can't improve your aim or trigger finger, unfortunately.


Warning: The checkpoints in LASO have been very sketchy ever since 343i patched out checkpoint sharing. The reason I say that is because even people who have played through the entire LASO playlist from start to finish together have lost their checkpoints midway through after quitting out. What's more, some have even had the LASO achievement not unlock if they weren't host. Keep this in mind, and try to only quit out after a mission is over/between missions if you have to stop for the day.


Now on to the tips.



  1. NOOB COMBO. Learn it, love it, live it. If you're new to Halo, the noob combo is using an overcharged EMP shot from the Plasma Pistol to drop an enemy's shields, followed by a quick Magnum/BR/DMR/Carbine headshot to kill the enemy. If you don't use this combo on Legendary when facing off against lots of Elites, you will die. A lot.

  2. Don't always assume your grenades have to kill enemies. Sometimes, especially for speed running, you'll want to use a grenade to flush enemies away from an exit and distract them so that you can run past them to the next checkpoint.

  3. Speaking of grenades, learn how to grenade-jump. It's a very useful tool for getting to hard-to-reach areas, and is even 100% necessary to get a few of the skulls. It helps bypass enemies at times, too. There's a particularly awesome grenade jump in the Library on Halo: CE that let's you skip a large area.

  4. For Halo CE, 2, and 3 - when fighting large groups of enemies, try to take out the leader first (Brute or Elite). This sends the Grunts into disarray and allows you to pick them off or run past. For Halo 4, focus on the Watchers first since they shield the enemies, then Knights, and lastly Crawlers.

  5. Don't expect to do everything in one go. This collection is massive. You're very likely looking at 300 hours or more to get all 6,000 gamerscore, if it ever even happens. Try to enjoy it. In fact, ignore this guide for now. Close this window and play through the game once without any crib notes. Seriously. What are you still doing here? Sigh.... fine. Have it your way.

  6. For multiplayer achievements (500 wins, gungoose aerial kill, etc.), if the achievement doesn't specifically state 'in matchmaking', it can be done in customs, local split-screen, whatever you like. Keep that in mind before you ruin someone's ranked matchmade game because you're trying to ramp your gungoose off every ledge on the map to get an aerial kill in it.

  7. For Par Times (and Legendary speed run) - get a partner (or three if doing Halo 3, ODST, & 4). You may not even have to take the specific route the speed runners do, because they have a tendency to do solo runs. Also, experiment with skulls. For instance, Grunt Funeral and Boom make Cairo Station much, much easier to speed run, especially with a partner. The So... Angry... skull makes some of the Brute-fighting levels in Halo 2 (such as Gravemind) much easier. Sputnik can make jumping out of the levels easier, which is helpful for some of the speed runs in Halo 2. Just don't use any of the afore-mentioned 0.00x multiplier skulls if going for par time, par score, or legendary speed runs.

  8. For Par Scores, once again experiment with skulls. If you're playing in standard 'Score' mode, you get a time bonus multiplier at the end, and it is based on the Par Time. It's up to 3.00x multiplier if under Par Time, and drops to 1.00x if you reach more than double Par Time. If you're playing in 'Competitive Scoring' mode, it factors in this time multiplier when awarding points for each kill, so the score you see is your TRUE score if you were to complete the level at that time. In Competitive Scoring mode, consequently, your score will start going DOWN after you pass more than double Par Time. The score requirements for the Par Scores have been greatly reduced for Halo CE, 2, and 3 with a recent patch, making them extremely easy to accomplish. Heroic difficulty with 2 or 3 scoring skulls on should be more than enough to reach most of them, but as stated just experiment with what works for you.

Cross-Title and Cumulative Achievements

Game Master - Pretty simple, just head into the local/customs lobby and edit something on any game type, then save it as a custom game type. Do this 5 times to unlock the achievement.

Bite The Hand - This will be a viral achievement. 343i employees will be in matchmaking on Nov 17th, and once a few people have killed them to get the achievement it should begin spreading… well, like a virus. You’ll likely get this inadvertently just by playing matchmaking on or any time after the 17th.

Throne of Bones should come earlier than the ones below, since there are only skulls to collect in Halo CE, 2, and 3. So if following the guide you should’ve unlocked ToB during the last level of Halo 3.

The next three, even if you’re a lone wolf, will come naturally if you’re going to make attempts at LASO because those attempts for most players, if not all, will be done in co-op to save the headache of restarting the whole level every time you die. If you’d like to knock them out early, or if you’re cheesing your way through some of the harder campaign achievements, you’ll likely have already unlocked these three when going through Halo CE or Halo 2. If not, just load up any level from any of the four games on Legendary Co-op and rush through to the end to nab this trio.

Similar to the individual game playlists, there are playlists in Halo:MCC that span two or more (and in some cases all 4) titles. The Master Chief Saga playlist is one such example, encompassing missions from all four games where the Master Chief’s story is told. Load up this playlist and see it through to completion to unlock Life Story, and in the process you’ll gain I Dabble in Slaying as well since MC Saga is a cross-game playlist.

Getting killed by the guardians is something that is as old as Halo. Basically, whenever the game cannot determine exactly HOW you died, or by whom, it simply defaults to those nebulous Guardians as the culprits. Just how long HAD Bungie been planning Destiny, anyway? I kid, but seriously, just play the game and in the normal course of play you’ll eventually be murdered by these mysterious beings during one of your countless deaths, at which point the achievement will unlock.

The Guardians Are Coming

Get killed by the Guardians.

So to all those who thought they were going to attempt to be the first to 4k this game and marathon-session it, risking personal injury/blood clots/etc – don’t! You can’t finish until 3 months after launch anyway, assuming doing it offline doesn’t work. Personally this achievement may very well be my final one in this compilation, but whether it is or not, I’m going to enjoy the experience and not rush it by any means. If you play at launch, then come February 11th, 2015 you should be able to unlock Stick With It either via matchmaking or co-op campaign.

Stick With It

Play a multiplayer or co-op game at least 3 months after your first game.

Stick With It

You’ll get the first several cumulative mission achievements just going through the four campaigns, at least if you do the campaign stuff first. A lot of folks might just dive right into that sweet, sweet Halo 1 & 2 multiplayer right off the bat. At any rate, completing 500 total games between campaign and multiplayer should come in no time at all. No explanation needed here.

Multiplayer wins: Another set of cumulative ones. You’ll likely unlock all of the above, including The Long Haul, before you get even halfway done with these, unless you don’t play the campaign much and win the majority of your multiplayer matches. These are once again cumulative, and I think we could’ve done with just the one for 10 wins, 100 wins, and 500 wins at most. The rest seem superfluous, but it’s likely 343i wanted folks popping achievements regularly while playing without going out of our way to do so, and in that sense it’s probably a good idea.

Also a key thing to note is that (at least for now) these are all obtainable in custom matches. The 'ene match' method was patched. However, Fooga here on TA has been nice enough to create a CTF map in Forge that will make the 500 wins achievement easy. Add Fooga to your friends list then search for his fileshare from within the game for a map called Construct Win Bonus. This is a Halo 3 map. Once you have downloaded it, go into custom games - Halo 3 - CTF - Multiflag. Start a game and it should give you the win without even leaving the black screen. For more details check his solution for the 500 wins achievement. Start a match 500 times for an instant win each time and all of the below achievements.

You’ll unlock most of these achievements merely by playing, but toward the end you may find yourself ‘grinding’ out the last few if you’re don’t play multiplayer a ton, because netting all of the campaign achievements probably won’t even get you half way to the 10,000 medal mark. One achievement here is of concern though. The one for 1,000 medals specifically adds the word ‘unique’ in its description, unlike the rest. This could potentially mean that you need to get 1,000 DIFFERENT medals across all four games. I doubt it though, since any one title doesn’t have 250 different medals you can earn, so having 1000 unique medals within the four would be a stretch. We’ll know soon enough.

Aim for the Head, Nice Work Dawg, and Dim Mak - Although these can technically be done in any of the multiplayers, hence why I'm leaving them on this page, they are easiest (and quickest) to do via H2A's forge mode. Go into forge in Halo 2 Anniversary on any map. I chose Lockout. In the map, go to Tools - Delete by Palette. Delete all spawn points. Now place one initial spawn and two respawn locations for Attackers and Defenders close together. Save the map. Next go into Customs with 3 controllers or 3 players. Play SWAT but change the weapon settings to BR, bottomless clip. Respawn time instant. Score to win 100 up to 150. Any higher lags the game out SEVERELY due to all the bodies and guns on the ground. Rounds to win 10. Have one person on one team and two on the other (the two going for the achievements). One person on the 2-man team body shots the spawning guy for assists, while the other headshots him immediately after. This can EASILY be done with 3 controllers as all you have to do is push RT on two controllers one right after the other over and over. The score limit shouldn't be any more than 150 though b/c the game can crash if you go much above 200, and lags badly after 150. I had mine set to 100 so it didn't lag for me much at all. You can just stand right behind the opposing spawn and beat the dummy controller down from behind over and over as it spawns to finish off the much-quicker 250 beatdowns.

Cumulative AI enemy kills achievements: Most of these will come naturally (100/1000 Grunts/Jackals/Elites). A few, like the 250 Hunters and the 1000 Watchers/Crawlers/Knights, may require going back in and grinding them. I’ve ordered them from most-plentiful to least-plentiful, leaving the Halo 4-specific enemies (Watchers/Crawlers/Knights) for last. I would move the Halo 4-specific enemies to that page, but seeing as they’re cumulative kill total achievements I figured I’d just leave them here with the rest.

One note about Halo 4's cumulative kills: Spartan Ops works as well as campaign. One user pointed out in his solution that he used Ep5 Ch1 of Spartan Ops to grind Knight and Watcher kills mainly, with a smaller number of crawlers there too. I cannot confirm if this is necessarily faster than the Midnight - Rally Point Bravo checkpoint method mentioned in the other solutions (specifically for Knights, that is), but it is an alternative to checkpoint reloading in campaign.

Getting 100 and 5,000 total kills will come easily. However, even if you do the 1000 kills achievements for Grunts/Elites/Jackals/Brutes/Hunters/Crawlers/Knights/Watchers, that will only bring you to 7,250 total kills. That leaves another 12,750 kills to grind across all campaigns and multiplayer. Assuming an average win rate of 50% in matchmaking, and the 500 wins achievement, that’s roughly 1000 matches of multiplayer. If you average 10 kills per game in matchmaking, then you’ll have 10,000 of that 12,750 done by the time you finish the 500 wins, leaving you with just 2,750 to mop up at the end. Of course some folks will do a lot better than that in matchmaking, and some will do a lot worse. At any rate, it shouldn’t be TOO much of a grind, and you can do it in campaign by just restarting a good checkpoint like Reach’s commendation system, so it should be easy enough.

Matchmaking-Only Multiplayer Achievements

*NOTE - From my testing I could not get ANY medals to count towards achievement progress in Halo 3. I did not test Halo 4. I can confirm that Halo 2 Anniversary, Halo 2 Classic, and Halo CE all worked toward these achievements, except for Roadkill Rampage and Rock and Coil Hit Back, which are specific to ONLY Halo 2 Anniversary*

The following wall-of-text guide will explain how to boost these achievements. If you wish to do them 'Legit' in Matchmaking, keep in mind the above information about the H2A-specific ones. More detailed information on what medals work will be below with each achievement where applicable.

First off, it's highly beneficial if one person boosting has 2 Xbox Ones. Even if you're boosting with 3 or 4 guys, you'll get the teams paired up much faster if the two XB1's hosting each 'team' are in the same house on the same ISP. So if you have this luxury, have the dual-box guy create each of the two teams, and the others join his teams, with dummy/extra controllers filling in the extra slots.

How to get matched up: Changing your console region to a less populated one such as Singapore or something has been said to help. I tried it and it didn't seem to make a difference. I didn't do it anyway because my dummy box was on Wifi and would lag out every time I searched on far-region servers. At any rate, have both teams' host xbox hit search on the chosen playlist at the EXACT SAME TIME. Communicate in party chat. It should say searching for players... If both xboxes don't see 'Players Found', at the EXACT same time, back out and search again. Even if they do, they should also see all subsequent messages like 'Joining Session'..;., 'Creating Teams...', etc at the exact same time too. If there's less than half a second of lag time between one person's matchmaking progression message changing and the other's, you might be ok. Anymore and it's unlikely you're matched up.

Alternatively, you can do the 'party invite method'. Player A is host, player B (2nd Xbox One with 3-4 players in the lobby depending on if boosting H2 or CE) is in party chat with Player A. Player A sends a game invite to the party then immediately switches to the Halo screen. When player B says he's accepted the invite, player A hits search on the matchmaking playlist you want to boost. ***The timing here is different for every partner depending on the lag time between you.*** Some people the timing will be for you to hit search as soon as they accept the invite. For others, you may have to wait 1-3 seconds before hitting search. Keep the party chat snapped to the side, and when you hit search, if the 'invite party to game' option stays greyed out and the player you invited shows 'In Your Game' underneath them, then you've most likely gotten paired up. If not, you'll have to back out to the playlist screen and try again.

Lets get on with the boosting, shall we? ((Note, as 343i may change the playlists from time to time, this guide may become invalid as far as specific playlists to use. However, the general strategies and ideas are the same. If playlists change and the guide isn't changed, just use common sense in picking which playlist to boost in for the respective achievements.))

Domination (100 legendary medals), Rock and Coil Hit Back (100 environmentalist medals), Double Trouble (250 double kills). - Search the Championship playlist. If it comes up, choose Lockout. Have one team all get in position under an icecicle. One guy on the opposing team shoots the icecicle for 1 Extermination (Domination), 4 Environmentalists, and one double kill. You can polish off double kills while working on all the other stuff after you finish the other two here. NOTE: Roadkill Rampage and Rock and Coil Hit Back's achievements have been moved to the Halo 2 multiplayer page, since they are specific to ONLY H2A multiplayer. I'm mentioning them here, however, because they fall into the "boosting any matchmaking-only achievements" category here.

The True King - As you're boosting splatters, if King of the Hill comes up on Lockout do the same thing as above in the Rock and Coil Hit Back boosting method, but when you're about to shoot the icecicle down on the enemy team try to jump into the hill. You'll get 4 hill defense medals each time along with all the others. Don't go out of your way to get into the hill though, because you want to be efficient at least until you finish Rock and Coil and Domination. Don't sweat this one though because it can be boosted in the Halo: CE playlist as well and KOTH comes up often there. Or just wrap it up in the Championship playlist once you're done with the others above, as KOTH is also frequently an option. Just have the opposing team group up in an open area with good sight lines to hill spawns. Jump into the hill and toss grenades at them if not going for splatters on Lockout to work on grenade kills and KOTH medals at the same time.

Party Pooper and mop up for Spree Master - Once again search CE and choose CTF classic, preferably on smaller maps but any map will do. The spawns in this game are fixed and are all near the flag. The only thing that impacts them is how close the enemy player is at the time the player spawns, and proximity to any teammates still alive. It's a 3v3 playlist, so have one person on the opposing team stand still, this is the guy going for Party Pooper. We'll call him Player A. A member of the opposing team (player B) comes across the map and stands a good distance away from him, but close enough to zoom in with the magnum and get headshots. He kills Player A's two teammates, waits for them to spawn, kills again, waits again, and gets a fifth kill, getting a killing spree. Player A kills him, earning a Killjoy.

Experiment with positioning. On Beaver Creek, for instance, I had Player A positioned directly above the flag on the grenades so his teammates wouldn't (usually) spawn outside the building, saving me time. I had Player B's teammates standing in front of their team's building so Player B would spawn outside, making the run across shorter. I then positioned player be just inside the doorway to the flag room to kill Player A's teammates. It helped that I was dual boxing and could see if/when they spawned around the corner. But keeping them from spawning outside the building is the most important thing on Beaver Creek. I was averaging 17-20 Killjoys per match, with a few as high as 26. When Player A gets 5 killjoys he'll be on a killing spree so Player B can kill him (keeping in mind to ensure he has a teammate alive nearby to respawn in a convenient location). This way Player A works on Killjoys and mops up on Killing Sprees, and Player B finishes Killing Sprees but gets a few Killjoys for his troubles. Helping a friend I managed to get him 36 killjoys in one match, so this can go VERY fast if you do it right.

Spree Master - A quick note on this one. It ONLY counts the FIRST killing spree you obtain for getting 5 kills without dying. Every other spree after that (Running Riot, Rampage, etc) and other sprees (splatter spree, etc) does not count. So once you get two exterminations when boosting splatters, or a killing spree in any mode whether boosting or playing legit, it's beneficial to die to reset your spree if you're concerned with knocking this one out.

Catch This - Just use the Championship playlist from Halo 2 and have the enemy team group up. Toss 1 plasma or 2 frags to kill them and get 4 grenade kills. This can easily combined with KOTH medals mop-up, or done in Halo CE CTF classic if you'd like to keep the enemies spawning in the same area to make your life easier.

Planting a Flag - Everyone knows about this one by now, but just in case, search Halo CE. Choose CTF classic. Have a person stand on their own team's flag. Stand right next to them so that you pick up their flag, and face them. Just start taping Right Trigger as fast as you can and watch the flag medals fly. Takes less than 2 minutes to two people their flag achievement.

Medals that count toward the Planting a Flag achievement are any flag-associated medals. This is best done in the Halo CE playlist as long as it's up because CTF comes up quite frequently and it's only 3v3, allowing you more breathing room getting flags. Medals that count toward this achievement, and their associated playlist, are as follows courtesy of BiggD from XBA.

  • Flag Taken – Take an opponent’s flag from their base (H:CE, H2, H2A)
  • Flag Returned – Return your flag to your base (H:CE, H2, H2A)

Again, I find Halo CE 'easiest' if playing Legit to get KOTH medals as the 3v3 means less chaos... and grenade spam... in the hill. Medals that count toward this achievement are as follows, once again courtesy of BiggD from XBA.

For Party Pooper, you need to kill someone that is on a killing spree of at least 5 kills. Yet again I advise Halo CE because if an enemy gets a killing spree, he's less likely to get whacked by one of your teammates before you can nail him since you only have 2 teammates in this 3v3 list.

Double kills come pretty frequently, although if you're struggling I'd highly advise trying to get into KOTH matches. Unfortunately people rarely vote for it in matchmaking, but if you're playing Halo 2 Anniversary or the Championship playlist, and it gets voted, you're in luck. Just keep chucking grenades into the hill whenever your team doesn't control it. You'll get lots of progress toward Catch This and The True King while you're at it.

Domination - So you wanna get 100 Legendary medals eh? I hope you're an amazing player, or your team is really, really good. You can get these lots of ways, but if going for them 'legit' I'd suggest SWAT as quite frequently one team will get the upper hand and win 50 to 30 or better, which is a steak dinner and thus should count as a legendary medal. At the time of this writing, the only game mode that consistently grants the Legendary medals, or at the very least progress toward the achievement, is Halo 2 Anniversary (H2A, Championship, and Anniversary Rumble). The following medals count toward Domination, yet again courtesy of BiggD on XBA.

  • Extermination – Wipe out the enemy team with at least an overkill
  • Killionaire – Kill 10 opponents within 4 seconds of each other
  • Perfection – Win a slayer game with 15+ kills without dying
  • Steaktacular – Play in a matchmade slayer game and win by at least 20 kills

Note: I mention using the Bandana skull in many instances to make the level-specific achievements, easter egg achievements, etc easier. However, using the Bandana skull (or any skull that has a 0.00x multiplier) will disable the difficulty-related achievements at the end of the game, as well as the mission-completion achievements (Pillar of Autumn, Halo, etc). I have still placed the mission-specific achievements at the end of each mission as well as the difficulty achievements at the end of The Maw, but remember that these won't unlock if using a 0.00x mulitplier skull. You'll have to replay each mission without any 0.00x skulls to do the Par Time, Par Score, and Legendary speed run achievements, however, so you will unlock all of those in due course. So don't sweat it if they don't unlock when using Bandana. It has been reported that they occasionally still do, but don't count on it.

We'll start off with an initial playthrough on Legendary difficulty using the Bandana skull extensively to focus on practicing Legendary speed run paths and to knock out collectibles and any in-mission achievements such as Look Out for the Little Guys, then move on to your Par Time, Par Score, and Legendary speed runs.

Halo CE

This first playthrough will be for Legendary and level-specific achievements, and for practice on the routes you'll take for speed runs. Easter egg achievements will be placed with their respective level in this section for all four games, but you may need to replay the level on a lower difficulty to make your life easier when going for Easter Eggs (when possible). A separate section will be devoted to the Par Time/Par Score runs for each game.

Also I’m going to say this now. Make sure to switch back and forth from re-mastered to classic version at least once in each level for the achievement for completing all levels in CE having seen it in both original and re-mastered (same for Halo 2). Just do it at the start of each level and continue on playing in re-mastered mode so you can grab the skulls and do everything bar the miscellaneous achievements in (mostly) one go.

At the end you’ll get:

Before and After

Halo CE: Complete every level of the game having seen it in both classic and remastered mode.

Before and After
1 guideOnline/Offline - These achievements can be obtained in either an online or offline game mode.Single Player - These achievements can be obtained by a single player.Cooperative - These achievements can be obtained by two or more players in a cooperative game mode who have met the achievement requirements.

Don't forget that if you're struggling with certain level-specific achievements (Walk it Off, Overshields are for Sissies, Watch Out for the Little Guys, Leave It Where It Lay, etc), you CAN use the Bandana skull to make those much easier. It doesn't void those achievements, just the level-completion ones, and since you're going to be doing multiple playthroughs anyway if going for LASO, Legendary speed runs, etc, you may as well use Bandana to make your life easier for the more frustrating miscellaneous/level-specific/easter egg achievements.

Skulls and Terminals

The video above shows all skull and terminal locations in Halo: CEA. Each mission's sub-section will refer back to this video with the time stamp to fast forward to. Most of us have gotten these already on the 360 version so you may not even have to refer back to this often. For Halo: CE you can get all the skulls on Normal difficulty or higher, while Terminals can be obtained on any difficulty.

Mission 1 - Pillar of Autumn

Activate Bandana for infinite grenades to make this easier and set the difficulty to Legendary. Always make sure to stay very far back when chucking grenades, and watch for ‘rebound grenades’, where sometimes an explosion will knock a grenade you throw back at you. This disables the speed run, but you’ll be doing a 2nd partial run of this level for Megg, a 3rd for the speed run, and a 4th for the par score. Keep in mind that separate runs for par time and par score are recommended unless you're a Halo ace. We are going to go for Walk it Off, Overshields are for Sissies, He’s Unstoppable, and Feet Firmly Planted all in this first run, as well as the skull/terminal . If for some reason you take health damage, just do a separate run on Heoric and be more careful to unlock He’s Unstoppable.

Once you exit the cryotube, switch to remastered mode and look behind the barrels opposite the exit door with the red/yellow/blue stripes on them to find the Iron skull (0:07). Don't forget to use remastered mode for collectibles, but always switch to classic mode at least once each mission for an end-game achievement.

Exit the room through the door by the NPC. Cross the hall but don’t jump over the pipes. Crouch up the sloped railing on the right to get on top of them without jumping. Turn right down the corridor behind them and continue straight through two doors. Turn left and crouch under the lowered bulkhead. Take the first door on your left in this hall and you’ll enter a dark corridor. Follow this hall to the end and you’ll see some marines in white outfits fighting covenant in the hall. Cross behind them into the next door and continue left down the next hall. Follow the corridor to the end, where you’ll find the bridge and Captain Keys. Facing Keys from the way you came in, look to your left (his right) to see a red-glowing terminal in remastered mode. Activate it for the first Terminal (0:21).

After the captain gives you your pistol, backtrack down the corridor to encounter a few Grunts. Deal with them and head to the door across the hall to the mess hall. Tons of Elites and Grunts will come busting into the room on the far side. For the speed run you would rush into this room all the way to the table in the far corner and jump onto it, hiding behind the wall for a second to let the enemies in before running past them to the next door. For this run, you’ll hang back in this hall with the three dead Grunts and just hail-mary grenades into the room. Chuck one or two at a time, and retreat back across the hall to the corridor leading to the captain to ensure you don’t take any splash damage from chain reactions. Once the room is cleared, cross to the far corner and exit the door.

Turn right into the corridor and take an immediate left into a doorway with a red arrow in front of it. Follow this corridor until you come up behind an Elite, who you can easily assassinate from behind. Take a right out the door past him, and follow the hall around to the left. You should see a red line on the wall to your right with the numbers 31 on it in white. Some enemies will come bursting out of that wall, so again take cover behind the corner and chuck grenades carefully to finish them all off. It should be 5 or so Grunts and an Elite. The small door they came out of contains an overshield, but we are ignoring it for achievement purposes.

Continue down the hall past where those enemies came out and around a couple of corners, looking for a doorway to the right with a green arrow in front of it. There is an Elite down this hall, so be mindful of that and either grenade or noob combo him from safety. Past him down the corridor you’ll come to a fork, go right. You should see a pool of blood on the ground in this hall. As you turn left you’ll see Elites in the corridor. Chuck a plasma grenade or two then retreat behind the wall. Continue throwing grenades into the corridor where they were to flush out and clear any remaining enemies. Once clear, exit out into the hall they were in and go to the right, then take an immediate right into a doorway with a health pack on the right of the frame. Be careful not to touch/pickup the health pack for achievement purposes.

Progress through this corridor until you run into a few Grunts. Kill them and throw grenades out into the next hall, trying to get them both to the left and right of the door. Clear the remainder of the enemies with more bottomless grenades before exiting into the hall and around to the right, where more Elites will come out. Again, just grenade them from safety before moving on. Again, an alcove to your right will have overshields, but leave them if going for the achievement. Go around the next corner and duck under the bulkhead, where you’ll find some magnum ammo by a dead body. Around the next turn you’ll come into a room with a set of stairs and elites on the ledges above. If you’re speed running you’ll go up the first set, then jump from the middle platform on the stairs up onto the ledge on the left.

For this run though, stay down and take cover in your corridor, chucking grenades up onto the upper ledges until you clear out all the Elites. Only poke your head out for one or two seconds at a time, as they will make quick work of you with their rifles and void the He’s Unstoppable achievement rather easily. Once the coast is clear, head upstairs, making sure not to jump at all, and into the next corridor. Lob grenades down to the far end to clear the next group of enemies. Be very careful here, as the enemies can drop plasma grenades, which can get knocked back toward you from the explosions, and will detonate themselves mid-air. Your best bet is to stay near the room with the stairs, throw a grenade or two down the hall, and retreat back into the previous room while things go boom.

Once the coast is clear, proceed forward, clearing the hall of Elites at a distance with grenades as per usual. Around the next corner or so there will be a health pack on the ground on the left side of the hall, so make sure to avoid it for the achievement. At the end of the hall clear the three grunts and go into the door where the nav point is to the dark, narrow hallways (maintenance accessway). Take an immediate left, and left again. At the next three turns go right, then left, and finally right. This leads to a door that opens out onto a hallway full of enemies. This part is tricky, especially if you’re trying not to take health damage, as this door closes when you get far from it. Use your frag grenades, step forward to open the door, and bounce one or two off the far wall so that they go left and right in the corridor, then retreat to safety while things go boom.

Continue this strategy until the hallway is clear. Go out and to your immediate left into the corridor on the far side of the hall, making sure to avoid grabbing the health pack on the right side of the door. Deal with the elite and continue to the end of this hall. You’ll pass some glass panes on the right looking down into a bay. At the end of the hall, turn right to see a few Grunts with flames everywhere and scripted explosions going off. Continue past the Grunts and into the doorway on the left, into a dark hallway. Kill the Grunt at the intersection, and another enemy down the hall to the right, before turning left. Turn right at the next corner, then left at the next intersection, to reach a door leading back out into the main corridors again.

Coming out into this hall, there will be Grunts to your left in the corner of the hallway. Deal with them and take cover behind the big support beams while you throw grenades down to the far end of the hall, where several Elites should be camped out. After clearing them, turn the corner and you should see a barrier in front of you with several enemies behind it. Grenade the enemies to death, carefully, taking cover around the corner while doing so in case any chain reactions ensue. Do not jump over the barrier, as it will void Feet Firmly Planted.

Facing the barrier, go into the door to your left, which leads to another maintenance access hall that takes you around the barrier. Once you reach the far side of the barrier, and all the enemies are dead, just approach the escape pod to end the level and unlock all of the following achievements (assuming you were successful with no overshields, no health packs, no health damage, and no jumping). You should have also unlocked My Buddy Chips at some point during the level without even trying, as it is virtually unmissable. You’ll also get Pillar of Autumn for level completion. If you're struggling specifically with Feet Firmly Planted, with the paths at the beginning and end of the mission to avoid needing to jump, check out THIS VIDEO for assistance.

If you struggled with any of the above achievements, run through a second time focusing on just that achievement while the mission is fresh in your head. Keep in mind that He’s Unstoppable can be done on Heroic rather than Legendary. Before moving on to the 2nd mission, restart the mission on Legendary to nab the Megg easter egg achievement. At the very beginning, head to the color-banded canisters in the corner where the skull is. Jump onto the red, then yellow one. Sit here for ~20 seconds. Now head through the level to the cut scene with Keyes where he gives you your pistol. Continue forward and kill three grunts and pick up your Assault Rifle in the next doorway, then head back to the bridge and shoot Keyes or kill a marine.

This triggers a group of invincible Marines to come out of a door behind you. From Keyes, turn around and head down to your left and around the corner to hide. When the Marines come around the corner to attack you, rush past them and head to your left and around the corner from whence they came. Beyond the door they came through is another door. Once through this door, head down the hallway to your right and shine your flashlight on the ceiling at the end to see an ‘M’ carved in bullet holes above you. Check THIS VIDEO for a visual guide.

There is a grenade jump off of a rock to get up onto the far ledge without crossing the bridge. This despawns the Banshees and Elites here at the first part, but it is extremely difficult to do. Check Nak3d Eli’s videos linked in the speed runs section if you would like to learn, as a video is worth 10,000 words. After getting the Mythic skull, cross the bridge and head up to the top of the hill and around the corner. You’ll see a drop ship unloading Covenant forces, so deal with them with your infinite ammo/grenades as you wish. Once they’re all dead, meet up with the Marines and you’ll trigger waves of several drop ships coming in around the large central structure in this area.

This area is extremely difficult to speed run, as you have to be perfect with grenade placement and clearing out these waves of enemies as soon as they drop. I would highly recommend having a co-op partner to speed up the killing, as well as studying Nak3d Eli’s video before attempting the run. Fortunately that isn’t what we are going for right now.

If you are in need of health, there are two health packs up on top of the large central structure, and a 3rd off to your left (when facing the large tunnel where you’re going next) by an evac pod. Once all the dropship waves are completed, a Pelican will drop off a Warthog for your traveling needs. Your next destination will be the large slope ahead of you leading down into a huge tunnel, but before you go down there, go up along the ledge to the right of that downward slope. Up here, behind a couple of trees in remastered mode, you’ll find the Boom skull (1:05).
