In total there are 65 onyx medals you need to earn in order to unlock the Seriously 3.0 achievement, you will also need to rank up to LV100 but that will most likely come automatically while going for the onyx medals (I'm Rank 59 and have only unlocked 2 onyx medals so far.). See my video for campaign boosting for a great way to earn XP. The medals have tiers, kind of like challenges in Halo: Reach, it goes bronze
The information about every medal will look something like this:NAME OF THE MEDAL
DESCRIPTION ( BRONZE / SILVER / GOLD / ONYX )
Every versus medal can be earned in private matches with custom settings VS casual bots or friends, I recommend you to set the number of bots to "Fill" if you're going to play the matches otherwise you will not be able to earn any of the important ribbons. However, if you are afk playing, it helps to put the bots at 1 or 2 cause you will still earn progress to most of the medals.
Also remember that you can choose what weapons will spawn on what place, if you're going for fire kills for example, set everything to hammer of dawns or scorchers.VENGEFULExecute (10/20/50/100) nemeses.
A nemesis is an enemy who killed you 5 times in a row without you killing him in the same match.
I don't have a super good method for this, I have been using 2 controllers and killed myself with the 2nd controller 5 times then executed the 2nd controller.CAPTOR
Kill (50/200/500/1000) enemies with a captive.
Press X while standing next to a downed enemy to take them as captive, you can only use melee and your pistol like this. You can knock out a great deal of these while going for leader captures.WAR SUPPORTERPlay in (5/10/20/30) Gears events.
Weird medal, been reported to unlock in private matches with different settings. The correct way to earn it is to play online during 30 different Gears Events, to check what events are coming up, go to the "Event Calendar" option in the main menu.MVPEarn (5/25/100/500) MVP ribbons.
You get the MVP ribbon by finishing a match with the most points. If you plan on playing vs bots, this will come way way way before you finish the 18,000 matches you need to play. Must be done with bots set to "Fill" or in a match full of players.FIELD SERVICEReach Level (25/50/75/100).
You gain EXP from pretty much everything in Gears 3. You get the most points out of playing Ranked Matches, however expect your opponents to be more skilled than in quick match. If you don't turn off your console you never lose your consecutive bonus either.VETERANPlay (100/500/2000/4000) matches.
Create a private match of Execution or Warzone, set it to 1 minute and fill it with bots. Make sure your controller doesn't go inactive by using a wired one or a battery charger cable. If you don't have any cables you can pull out your battery pack during the countdown screen before the matches begin. Go sleep or go to school/work and when you come back you'll have tons of matches played.MATCH WINNERWin (50/250/1000/3000) matches.
Same as "VETERAN" except you can play the matches yourself if you really want to win every one of them. You can also plug in a 2nd controller for the other team to even out the odds.HEADSHOTGet (100/500/2000/4000) headshots.
You can score headshots with most single-fire weapons. Easiest for me is to down someone, then fire 2 rounds in their head with the snub pistol.HEAVY WEAPONSGet (100/500/2000/6000) heavy weapon kills.
One-shot, Mulcher and Mortar counts as heavy weapons.EXPLOSIVESGet (100/500/2000/6000) explosive kills.
Grenades, Boomshot, Torque Bow and Digger counts as explosives.FINISHERGet (100/500/2000/6000) executions.
You execute someone who is downed by pressing Y or X (meat shield) while standing next to them, chainsaw-kills and bayonet-charges also counts as executions and stack with kills for that weapon.SKUNKERSkunk enemy team (25/100/500/2500) times.
Win without letting the enemy team win a single round, cannot be won in 1 round matches. Recommend you to go for these while going for "Sovereign" and "Leader" medals or if you want them done as quick as possible, Warzone set to 2 rounds will be best. Must be done with bots set to "Fill" or in a match full of players.LEADEREarn (10/50/150/300) Untouchable ribbons.
You get the untouchable ribbon by finishing a round of CTL as leader without letting the enemy capture you at all. There is a trick to make you leader every round, you need to have 2 controllers and a dummy profile. Make your dummy profile the main player by pressing start with the 2nd controller at the "PRESS START"-screen, this will make your dummy profile the main player and you the secondary player. Start a match of CTL with rounds to win at 1 and cap time at 10, the key here is to put both you and your dummy profile on the same team vs 5 bots. The first match you start will have the dummy as a leader but every match after that you will be the leader! Must be done with bots set to "Fill" or in a match full of players.ABDUCTORCapture (25/100/250/500) enemy leaders.
Earned in CTL by grabbing the other teams leader for as long as it takes to win the round. Must be done with bots set to "Fill" or in a match full of players.ASSISTANTGet (125/500/2000/5000) assists in Versus multiplayer.
Damage an enemy and let a teammate get the kill. Will surely come by itself if you plan to play in real matches online, if not, wait till you knocked out all the kill medals, then play KOTH or CTL with insane bots, find a place with a good view of the map and just spot and spray with your lancer, letting the bots do the killing.MEDICRevive (50/250/600/1200) squadmates.
Press X while standing next to a downed teammate. These will most likely come while going for all the other medals, just revive whenever you have the chance. If you really want to knock these out fast, play CTL with bots and turn friendly fire on. Keep hitting/shooting your leader till he goes down, then revive him, rinse and repeat.COVEREarn (10/50/200/600) Buttoned Up ribbons.
You earn the Buttoned Up ribbon by spending the most time in cover in a match, using a meat shield will also count as cover. If you have a turbo controller you can get these while you let your game sit by putting something heavy on the a button. You'll get this medal every match this way. Must be done with bots set to "Fill" or in a match full of players.ACTIVE RELOADER(500/2500/10000/25000) perfect active reloads.
Will most likely come naturally while going for kills, otherwise, the snub pistol is the fastest gun to reload, master it and spam reloads.LANCERGet (100/500/2000/6000) Lancer kills.
Chainsaw kills counts as well.HAMMERBURSTGet (100/500/2000/6000) Hammerburst kills.RETRO LANCERGet (100/500/2000/6000) Retro Lancer kills.
Retro charge kills counts as well.GNASHER SHOTGUNGet (100/500/2000/6000) Gnasher Shotgun kills.SAWED-OFF SHOTGUNGet (100/500/2000/6000) Sawed-off Shotgun kills.PISTOLSGet (100/500/2000/6000) pistol kills.
Snub, Gorgon and Boltok are the pistols. Try to pick up a meat shield so you can work on "CAPTOR" at the same time.SPOTTERSpot (250/1000/5000/12000) enemies.
Aim at an enemy and press your left stick will spot them. Try to do this as often as you can while working on Rifle kills etc.PYROKill (50/300/1000/3000) enemies with fire.
Scorcher, Hammer of Dawn and Incendiary grenades are the fire-based weapons.SAPPERDestroy (10/50/200/1000) enemy grenades.
Shoot a grenade that is tagged to a wall or to the floor by an enemy. Easy, but tedious, to boost with a 2nd controller, just tag the smoke grenade you start with and shoot it with your main profile. You can also team up with a buddy for it, ViiETx
made a video for that. Click here
to watch the video.GUARDIANRescue (50/250/600/1200) leaders in CTL.
Make an enemy release your leader by throwing a smoke grenade at him/her or kill/down him/her. Chances are these won't come naturally, then you can put yourself and a casual bot on one team, a second controller on the other team. Put the bleedout to 5. Make it so the bot is the leader by finishing the first round (if he's not leader from the beginning.) then you just have to keep capturing him with your second controller and rescue him with your main profile. You can team up with a buddy to replace the bot if you want this to go smoother.CTLPlay (100/300/1000/3000) CTL matches.
Same as VETERAN, except you can't set a time limit but set the capture time to 10 seconds. If you're going to idle play you can plug in a 2nd controller and set the number of bots to 1, make it so it's you and the bot vs the 2nd player. This will end the matches swiftly and you'll always win thanks to the bot on your team.KOTHPlay (100/300/1000/3000) KOTH matches.
Same as VETERAN, except you can't set a time limit but set the ring score to 60. If you're going to idle play you can plug in a 2nd controller and set the number of bots to 1, make it so it's you and the bot vs the 2nd player. This will end the matches swiftly and you'll always win thanks to the bot on your team.WARZONEPlay (100/300/1000/3000) Warzone matches.
Same as VETERAN. I always fill these with bots and maybe even put the time limit at 2 to earn as many "Last Man Out" ribbons, you need 3000 of these for the "HARD TARGET" medal.EXECUTIONPlay (100/300/1000/3000) Execution matches.
Same as VETERAN. I always fill these with bots and maybe even put the time limit at 2 to earn as many "Last Man Out" ribbons, you need 3000 of these for the "HARD TARGET" medal.TDMPlay (100/300/1000/3000) TDM matches.
Same as VETERAN, except you can't set a time limit but set the stock to 10. I always fill these with bots and maybe even put the time limit at 2 to earn as many "Last Man Out" ribbons, you need 3000 of these for the "HARD TARGET" medal.WINGMANPlay (100/300/1000/3000) Wingman matches.
Best method is to use 2 controllers, put them on one team, make the amounts of bots 2 so it will be a 2v2 match. Set the time limit to 2 (For those really big maps like sandbar) and disable all weapon pick ups. The bots will rush and kill you almost right away for some reason, ending the match in 4 rounds.ALLFATHERS(Bronze/Silver/Gold/Onyx) Medal in all game modes.MASTER-AT-ARMS(Bronze/Silver/Gold/Onyx) Medal with all 5 starting weapons.RIFLEMAN(Bronze/Silver/Gold/Onyx) Medal with all 3 starting rifles.HARD TARGETEarn (100/300/1000/3000) Last Man Out ribbons.
Be the last person on your team to die, cannot be obtained in KOTH, Wingman or CTL. You'll knock out a great deal of these while afk-playing TDM/Execution/Warzone. If you still need more, turn on friendly fire and play private Warzone games vs bots. As soon as the spawn protection is over, kill all your team mates with the Gnasher and you'll earn a Last man out ribbon. Finish the match by suiciding or just kill everyone on the opposing team. Must be done with bots set to "Fill" or in a match full of players.SHOCK TROOPEREarn (100/300/1000/3000) First Blood ribbons.
Score the first kill of the round, can be earned in horde and beast as well but only once per session, not every wave. Must be done with bots set to "Fill" or in a match full of players.OLD SCHOOLERCurb stomp (50/250/1000/3000) enemies.
Press Y (don't hold) next to a downed enemy to execute them with a curb stomp. Stacks with "Finisher" medal.BATTLE MISTRESSPlay as a female in (25/100/500/1000) matches.
The female characters are Sam, Anya, Civilian Anya (COG) and Myrrah (Locust). See VETERAN for quick method.SOVEREIGNWin (25/100/250/500) CTL rounds as leader.
Almost the same as untouchable, except you can get picked up, you get credit as long as your team wins the round.SPECIAL TEAMSGet (100/500/2000/6000) map-based weapon kills.
Every weapon that is not among the 5 starting weapons count as a map-based weapon.
------HORDE MEDALSFOR THE HORDE!Completed all 50 waves of Horde on (Casual/Normal/Hardcore/Insane).

Everything that gives you points gives you the same amount in cash, completing challenges also earns you cash. It's probably best to keep playing boss waves with mutators on.LOOT COURTESANComplete (10/20/50/100) challenges in Horde.

Cumulative.MOTIVATORHeal or revive (250/300/750/1500) teammates in Beast.
You have to play as the Kantus or Armored Kantus for this. Press X for your heal/revive scream. My method for these have been to join standard public games and play the savage drone until the Kantus is unlocked, then I just play the Kantus and spam X, can't heal all characters though, only those who are marked with a Locust emblem. You'll be surprised how fast this one goes up!DISMANTLERDestroy (150/500/1500/3000) fortifications in Beast.
