3. Story walkthrough
Every achievement can be earned in one playthrough if you have a co-op partner at the start. However, some achievements cannot be shared so a few would require selecting a mission and helping your buddy with a replay. Every achievement is listed below with a description on how to unlock them. For this guide, we'll assume you're playing on Legendary
CAMPAIGN WALKTHROUGH
| Chapter 1 - Pillar of Autumn |
Skull: Iron
At the start of the mission, look at the very back of the area near a cryo tube.
Terminal: After talking to Keyes turn left and you should see a blinking Red computer.
Complete the level “Pillar of Autumn” on Legendary without picking up a health kit.
Do not pick up a health pack. Unfortunately if you lose any health it's actually VERY easy to accidently pick one up.
Complete the level “Pillar of Autumn” on Legendary without picking up an Overshield.
You can find four overshields in the pods the Covenant enter in. Easy to avoid these as they aren't in your path. Just pretend they aren't even there.I would try to do this one at the same time as "Walk it Off".
Complete the level “Pillar of Autumn” on any difficulty.
Awarded for chapter completion.
Skull: Mythic
Located in the waterfall at the start of the mission.
Skull: Boom
Before entering the first tunnel of the mission, walk along side the hill near said tunnel.
Terminal: In the tunnel you arrive in after the Warthog is dropped off you will see a Yellow light down the ramp.
Destroy three of the four Banshees on “Halo” on any difficulty during a single play-through.
At the start of the chapter you will see two Banshees approaching. Use a pistol take them both out before they get away. Later when you're on your way to save the 2nd group of Marines you will encounter two more Banshees. Just destroy one more for your achievement.
Complete the level “Halo” on any difficulty without entering a vehicle.
Finish the chapter without getting into a vehicle. In the first tunnel there is a huge gap in which you would normally need a Warthog to cross. Using a grenade you will need to jump across the gap in order to proceed. However, if you aren't the best at grenade jumping you can have a co-op player use the Warthog and jump the gap to proceed as normal, which will teleport you across.
Complete the level “Halo” on any difficulty.
Awarded for chapter completion.
| Chapter 3 - Truth and Reconciliation |
Skull: Foreign
In the hangar bay, hidden inside the far left door in the back.
Terminal: On the raised platform in the room approaching Keyes' location you will see a flashing Red light.
Kill all the enemies in the first encounter of “Truth and Reconciliation” without being detected.
At the start of the chapter you will need to snipe every enemy without them returning fire. Stay back and take time with your shots. This video will help. Alternatively, you can come back later once you've obtained the bandanna skull and spam grenades from a safe distance.

Complete the level “Truth and Reconciliation” with at least four rounds left in your Sniper Rifle.
This is easier solo as when you die you won't have to search everywhere for your sniper rifle. It's filled with ammo so keeping at least four rounds is pretty easy. Just pay attention to your ammo if you plan on using it a lot. In co-op, if you lose your weapon and cannot find it just revert to the last save.
Complete the level “Truth and Reconciliation” on any difficulty.
Awarded for chapter completion.
| Chapter 4 - The Silent Cartographer |
Skull: Famine
At the start of the mission, turn around and you will see a hill. Walk up the hill and it will be at the very top.
Terminal: In the area with two Hunters and two overshields you can find a flashing Yellow light in the middle.
Skull: Bandanna
Near the security console on the right, you will need to grenade jump up to a ledge in order to reach this. If you’re having problems making the grenade jump, you can use a second player to help you reach it. See the video below.

Storm the beach of “The Silent Cartographer” with no marine casualties on Heroic or Legendary.
At the start of the chapter, rush in and throw grenades at the first few to avoid them killing the Marines that rush in. Focus on where each enemy is at. It may take a few tries.

Escape the map room in “The Silent Cartographer” without firing a shot on Heroic or Legendary.
When it's time to escape the Map Room do NOT pull the trigger to fire. Melee and Grenade your way out. The Bandanna skull provides infinite grenades which also makes this achievement easier. The achievement unlocks when the level is over.

| Chapter 5 - Assault on the Control Room |
Skull: Fog
In the middle of the room you enter before you make it to the Canyon
Skull: Malfunction
In the large room, with two bridges, you will need to walk towards the edge and look down. A ladder can be found that leads to the skull on some type of pipe like structure.
Terminal: Near the end of the level approaching the pyramid-like structure, a long beam will lead down into a crevice. A Yellow flashing light can be seen.
Destroy four Wraith tanks in “Assault on the Control Room” with the Scorpion tank, in a single play.
There are four total you can kill with the tank. The ones at the end of the level cannot be reached. Here is a video to help show the Wraith locations.
Only one player can earn this at a time. Co-op Wraith kills aren't shared.

Pilot a Banshee on the level “Assault on the Control Room.”
You will need to get to a Banshee before an Elite takes it on Assault On The Control room.

Another way would be to follow the speed run on the previous page in which taking a Banshee is a must.
Complete the level “Assault on the Control Room” on any difficulty.

| Chapter 6 - 343 Guilty Spark |
Skull: Recession
On the left of the structure you enter there is a Shade Turret and next to it is a spot you can drop to. Head left and it will bring you to the skull.
Terminal: On the elevator you use to escape the facility, jump off onto the top part of the structure with a Yellow Light
Kill 50 Flood Combat Forms on the level “343 Guilty Spark” on Heroic difficulty or higher.
The ones that fight back are the ones you are after. There are so many enemies that you will easily get this as you fight your way out. It may be a close shave in co-op as less kills for you.
Escape the Forerunner facility on the level “343 Guilty Spark” in 21 minutes or less.
Easy to do if you do not get lost. Try to prevent yourself from turning around as everything looks the same. Also keep in mind that you will need to hop on some boxes to reach higher ground and escape. The achievement pops when you get outside.
Complete the level “343 Guilty Spark” on any difficulty.
Awarded for chapter completion.
Skull: Black Eye
Run straight from the start of the level to the end near a big square-like object. Grenade jump on it and hop onto the far vent and walk into it until you find the skull.
Terminal: On the 3rd floor, before the floor to the index, you will need to get to the back of the circular area. Crouch jump off the walls to advance to the other side. You can notice the Yellow Light in the distance.
Skull: Eye Patch
Instead of grabbing the Index and ending the level, run around the back of it to find the skull.
Complete the level “The Library” on Heroic difficulty or higher without dying.
You cannot die and continue from a checkpoint. There is a trick though. As you play along, save and quit at each elevator checkpoint. This means that if you die, you may quit to the dashboard and restart the game without it counting your death. In co-op BOTH players must make it to the end without dying. Practice makes perfect. Use the Bandanna skull.
Complete the level “The Library” on Legendary difficulty in 30 minutes or less.
With the Bandanna Skull and a Shotgun this can be pretty doable. Never turn back and push on through the massive Flood attack. This is a lot easier in co-op.

Complete the level “The Library” on any difficulty.
Awarded for chapter completion.
| Chapter 8 - Two Betrayals |
Terminal: At the start of the level you can find the Yellow light behind you on the opposite side.
Skull: Pinata
When you grab the last Banshee instead of flying to the Nav Point you will find your skull on the snowy ledge above the tunnel you recently exited.
Complete the level “Two Betrayals” on Heroic difficulty or higher without killing any Grunts.
For this achievement the only hard part is early on as thats where all the Grunts are. Later on you can just wait for the flood to kill the Grunts. If you yourself kills a Grunt revert to last save.
Complete the level “Two Betrayals” on Legendary difficulty without picking up a new weapon.
On Legendary with the Bandanna skull this is an easy achievement as you won't have the need to pick up a new weapon.
Complete the level “Two Betrayals” on any difficulty.
Awarded for chapter completion.
Terminal: In the room where you find Flood Keyes you can find the Red light on the right crevice in the floor.
Kill 100 Flood Infection Forms on the level “Keyes” on Heroic difficulty or above.
There are so many of these little popping Flood freaks that if you are on Heroic or Higher this achievement will just come naturally.
Kill every Elite on the level “Keyes” on Heroic difficulty or above.
The Flood assist you with this one. However search everywhere before proceeding into a new room. You need every single Elite dead on Heroic or Higher. Most will be found in the Hangar Bay.
Complete the level “Keyes” on any difficulty.

Terminal: In the Control Room for the Cryogenic Storage Bay (remember the first level right when you start and you see that window) you can find the Red light on the wall.

Complete the Warthog ride on the level “The Maw” without being forcibly ejected from your vehicle.
Escape “The Maw” on Legendary with at least a minute left on the count down.
These achievements aren't that bad. If you played The Maw a lot back on original Xbox these should just come natural to you. If the Warthog flips, just revert to last save.
