Introduction:
"All right sweethearts, what are you waiting for?" (Apone) You know every line and can quote the movies from memory. Now it's time to see if you have what it takes to be in their universe! Welcome to Aliens: Colonial Marines, where not only will you play as a marine but can experience multiplayer as a Xenomorph. (That's just so much fun to say, Xenomorph!) *cough* Excuse me, what were we talking about? Oh right. The achievements for this game aren't as difficult as they may appear. Thankfully experience is earned for your marine through all game types making the time needed to get the full 1,000 faster. Also several achievements can be earned using multiple methods in the campaign or multiplayer (even private matches). This roadmap is broken up into three easy steps to help make your triumph over this game even easier.

Saves:
This game unfortunately doesn't have a traditional save system. If you look for your save file, you won't find one. This game saves into your cache. Unfortunately, if you clear your cache it will wipe out your progress. For those online, it also will make a server side save for your profile which can cause various problems such as ranks being reset. Ultimately, this means any achievement that requires tracking could not unlock or outright stop tracking (as is the case with my game) for apparently no reason and with no possible recourse at this time. The most succesful method so far has been to recover your profile, but even that is no guarantee. Good luck to all the completionists out there.

Step 1: The Campaign:
While it is possible to get all of the campaign related achievements in one playthrough, I wouldn't recommend it. Personally I'd try for 2 playthroughs, especially since the achievements unlock on Recruit difficulty and the difficulty level achievements stack allowing you to unlock "Not Bad For a Human" when you finish your Ultimate Baddass playthrough. The extra playthough will add more experience towards your marine's rank and gives you more opportunity to work on the campaign section of challenges.

Your first playthrough on Recruit should be used to knock out the majority of campaign related achievements. This includes collectibles, mission specific tasks, etc. Doing this will also help you become familiar with the levels' layouts and controls for your next playthrough. Use "restart checkpoint" to your advantage if you miss something or wish to farm a location.

Your second playthrough on Ultimate Badass is a lot easier with friends, especially reviving each other. Take advantage of your knowledge from the first playthrough and check the guide below for useful tips.


Step 2: Multiplayer:
A large portion of the achievements appear to be intended for multiplayer but can be unlocked in various game modes, even campaign. Most of your time will likely be spent trying to level up your marine for the related achievements as well as finishing all of the challenges. The guide will have effective boosting methods listed for all of these. Private matches on XBL (offline requires a system link, split screen versus doesn't work) are very effective and can help unlock several achievements.

Step 3: Cleanup and/or Boosting:
Anything you may have missed or need help with, now is the time to polish off that 1000! Achievements can be earned in private matches as well. Organize boosting parties or find partners using THIS THREAD.Campaign allows you to use mission select to work on a specific level's achievement. Restarting checkpoints is a great way to boost kills and work on campaign and/or marine challenges.



Stasis Interrupted


Step 1: Playing the DLC
Start the DLC on the hardest difficulty so you do not have to play through it more than once. You should get all of the achievements in this one playthrough unless you miss something or an achievement does not pop. I Don't Got All Day and We Are Leaving! have been reported glitchy but replaying the level again on recruit seems to unlock the achievements just fine. You should get all of the audio logs, shoot the umbilical without missing and kill all the lurker in mission 2, and destroy all samples in the gas rooms in mission 4 to avoid replaying any level.

Conclusion:
Other than taking time to boost or grind out the leveling related achievements, this game is a quick 1000. Help from friends will have you saying "Game over, man. Game over!" because you've done everything so quickly. So now you just need a deck of cards to pass time until more achievements are added with DLC.
 


[x360a would like to thank Grifter Reborn for this Roadmap]
[x360a would like to thank littlejay for the DLC addition]



Another Day in the Corps!20
Complete Distress (2) 

Story related, can't be missed. "See Game Over, Man" for more info. Unlocks when you've finished the first mission (Distress).

Bad Feeling About This Drop20
Complete Sulaco Falls (1) 

Story related, can't be missed. See "Game Over, Man" for more info. Unlocks when you've finished mission 3 (Sulaco Falls).

Quoth the Raven20
Complete The Raven 

Story related, can't be missed. See "Game Over, Man" for more info. Unlocks when you've finished mission 5 (The Raven).

Still Got a Job to Do20
Complete Rampart 

Story related, can't be missed. See "Game Over, Man" for more info. Unlocks when you complete mission 8 (Rampart).

Dragged Queen20
Complete Home (12) 

Story related, can't be missed. See "Game Over, Man" for more info. Unlocks when you've finished mission 11 (Home).

Game Over, Man!30
Complete all Campaign levels on any difficulty (1) 

As mentioned in the roadmap, I recommend your first playthrough on the easiest difficulty (Recruit) since you can find all of the collectibles and learn the layouts and controls along the way. This is a good time to try for level specific achievements, such as "Short Controlled Bursts," since there won't be much challenge and you can restart checkpoints. This achievement will unlock as the credits roll.

Not Bad For a Human40
Complete all Campaign levels on Hardened difficulty (4) 

This achievement unlocks when you finish the campaign on Veteran difficulty. See "State of the Badass Art" for more info.

State of the Badass Art50
Complete all Campaign levels on Ultimate Badass difficulty (41) 

If you're able to join random games, you don't have to beat the entire campaign on this difficulty. As long as you join before the end of the mission, you'll receive credit. This means some unlucky person could fight through 90% of the mission and you join for the last 10% and receive credit for beating the mission. (Lucky you!) To see which missions you've completed, select "service record" from the menu and select "records". The first highlighted screen (campaign records) will list all 11 missions with the difficulty you've completed. If the cheevo doesn't unlock, try doing one mission solo (mission 11 is pretty easy) to get it to unlock.

Co-op is easier if you have the opportunity, but watch friendly fire especially flame thrower. Enemies are tougher and do more damage. Revives will help a lot along with good communication for solid teamwork. If going solo, use the parts of the campaign where you have help from NPC's to your advantage. You will also have no "HUD" during this playthrough so ammo and reloading can become tricky. Find co-op partners using THIS THREAD.

Short, Controlled Bursts20
Defeat all Xenomorphs in the Sulaco hangar bay without them crossing your barricade (20) 

About halfway through mission 1, you will return to the hangar bay where there is a keypad Keyes will try to open while you defend a small barricade between him and the dropship. Stand between the barricade and the dropship and stop the aliens until Keyes opens the door and tells you to fall back. Watch the video below for the strategy and when to fall back.

Fire Drill20
Arm the emergency release and escape in under 2:30 on Sulaco Falls (4) 

The end of Sulaco Falls (Mission 3) is a hanger where you must operate some computer terminals while fighting Weyland's troops. When you enter the hanger, there will be an upstairs platform that you need to get up to. In the first room there's a computer to arm. Once finished, proceed to the end of the platform where the next computer is. Before you get to it, your "walkway" will collapse. Turn around to see a new room open up (with enemies inside) and once cleared, use the computer in there. Wait for the new pathway to arrive and proceed to the final computer. Once you're finished, quickly hop down to the lower level and proceed to the ramp of your dropship. This will unlock on Recruit difficulty if you finish under 2 and a half minutes when the cutscene starts to play. If your takin too long, pause and select "restart checkpoint" to try again. The video below shows the layout and strategy.

Mostly Come at Night...20
Find Newt's doll (19) 

Newt's doll, well actually it's just a doll's head (named Casey, in case you're wondering), is located in the sewers in mission 5 (The Raven). If you've made it to the door you cut through, you've gone too far. This is after activating a pump and watching some exploding aliens attack it. Just past this spot are some barrels with the doll's head resting on top.

Just a Grunt20
Complete Hope in Hadley's (5) 

Story related, can't be missed. See "Game Over, Man" for more info. Unlocks when you complete mission 9 (Hope in Hadley's).

No Need For Alarm20
Complete One Bullet without setting off the alarm (1) 

You need to get through the labs without setting off an alarm in mission 7 (One Bullet). The very first scientist will spot you and set off an alarm. This is inevitable, but won't influence the achievement. Speed (and shotgun for close quarters) is your best friend for this. Each time you open a door, you must quickly kill everyone in the room before they hit an alarm (located on a wall). If they spot you everything is fine, they are just not allowed to use the alarm switch. Rush in with a shotgun on Recruit difficulty and kill them quickly. If they reach an alarm, it will begin a countdown. If you hit the switch () to cancel the countdown, the achievement will still unlock. If you're sure you've set off an alarm, pause and select "restart checkpoint" to try again. The achievement pops when you've completed the mission.

Heavy Lifting20
Defeat the Raven in under 1:10 on Soldier difficulty or higher (17) 

The Raven has been chasing you the entire mission (more or less) and at the end you finally get a stand up fight against it. Get inside the loader and use  and  to punch your way to victory. Be warned, the loader isn't very nimble making this fight a challenge to get in just over a minute. If you're struggling, pause and select "restart checkpoint" to try again. The video below shows how the successful fight should look.

Adios, Muchachos20
Gib two enemies at once (11) 

This should say "aliens" or "Xenos" instead of "enemies". This doesn't work on the missions where you fight other soldiers. (However those "gibs" count for challenges.) I unlocked this on mission 1 (Distress) after you cut Keyes down. The first room you encounter aliens, stay back at the door. Most of the aliens will go towards Keyes, line up a shot with your underslung grenade launcher ( on your pulse rifle) when 2 are close together. Restart checkpoint if you miss or it doesn't kill both before you reach the stairs on the other side of the room. Recruit difficulty.

Field Promotion10
Earn Rank 2 as a Marine (1) 

See "I Love the Corps!" for more info.

Lean and Mean20
Earn Rank 20 as a Marine 

See "I Love the Corps!" for more info.

I Love the Corps!40
Earn Rank 60 as a Marine (18) 

Reaching level 60 goes pretty fast since progress towards your ranks can be earned through all game modes. One great method for earning XP (aside from completing challenges) is to play a 2 vs. 2 Extermination private match. (Note: host will always be an alien for the 1st round) When you're a marine, each of you take a waypoint to stand in a circle to destroy eggs. Destroy as many as you can before time runs out. By the end of the round, you'll easily have over 1,000 XP earned. As an alien, just chill.

Experience is earned from kills, collectables, completing challenges, match bonuses and campaign chapters completed. Assists are unconfirmed.

Mission 11 (Home) is a great way to rank up too. Complete this mission on Ultimate Baddass for around 2,800 XP. This level is incredibly easy with 2 people, one occupying the queen and the other presses the first 4 buttons. Meet up behind the last button, wait for the queen to get on the path and BAM! Let her have it.

Oorah to Ashes10
Collect a Dog Tag (1) 

See "Remember the Fallen" for more info.

Remember the Fallen30
Collect all 35 Dog Tags (5) 

For video guides, I recommend using THIS THREAD.

There are 35 total dog tags to be found. If you're playing co-op, you must pickup the dog tags for them to count. If you don't see a dog tag at the correct location, try pressing  around the area to pick it up. For some reason, they sometimes don't appear on screen even though they are there. Once you've picked it up, it is saved to your service record. To check your progress from the main menu, press  on "Service Record" and again on "Special Projects".

The breakdown for each level is:
Level 1- 3 total (Hicks, Moore, Trubetskoy)
Level 2- 3 total (Dietrich, Forcher, Ziglar)
Level 3- 3 total (Frost, Greenlief, Ashley)

Personal Friend of Mine10
Collect a Legendary Weapon (18)

I Like to Keep These Handy30
Collect all 6 Legendary Weapons (6) 

For the video guides, use THIS THREAD.

If you're playing co-op, you must pick these up yourself. To see your progress, follow the same process for dog tags, except press  when looking at dog tags to see the weapons. There's a total of 6 legendary weapons on the following levels:
Level 1- Hick's Shotgun
Level 4- Gorman's Pistol
Level 5- Hudson's Pulse Rifle
Level 6- Vasquez's Smart Gun

Distinguished Service Medal30
Complete all Challenges (146) 

Challenges become available in sections that need to be completed in order to unlock more. Each category will have 1 active challenge, giving you 3 challenges that are available at a time. There are a total of 86 challenges that grant 500 XP for each one completed towards your marine's rank. Please note that Legendary Weapons may not count towards some challenges. For example, Hick's shotgun is a "pump shotgun", but as for the challenges that say "pump shotgun" (Boom Stick challenge) using Hick's weapon won't count.

Don't Count Me Out5
Revive a teammate (1) 

When a player is "downed" in co-op campaign, they will be sitting on the ground with a pistol and a red bar above their head. Approach them and hold  when you're prompted to and this will unlock once they're back on their feet.

Ready to Fry Half a City5

Those that have preorder weapons can unlock this immediately by selecting the weapon for your custom loadouts. Everyone else can unlock this at level 3 when the assault rifle is unlocked. To equip a weapon from the menu, go to "versus", "edit loadouts", "marine loadouts". Press  on primary and select the weapon you wish to equip for the achievement.

Structural Perfection5

You Look Just Like I Feel30
Upgrade every Appearance slot once for your Marine (3) 

To edit your marine's appearance from the menu, go to "versus", "edit appearance", "marine appearance".  and  switches between the male and female appearances (excluding preorder bonuses).

I Can Handle Myself40
Purchase all Upgrades for a weapon (2) 

The earliest you can unlock this achievement is when you reach level 18 for your marine. Upgrading the combat pistol is probably is the easiest weapon to get this with. It has 3 upgrades needed for the achievement (skins don't count) and all of them are unlocked before any other weapon. From your menu, press  on "versus" then, under the word "customization", highlight and press  on "edit loadouts", "marine loadouts". Press  to customize when you've highlighted the weapon bringing up your upgrade screen. You'll be able to select upgrades you've unlocked so far and spend points (located in your upper right hand screen) to purchase them. You need to purchase the attachment, sight, and fire mode for the combat pistol to unlock this.

Majority Shareholder25
Spend 30 Commendations 

Commendations are the points you receive to purchase upgrades with. These are earned each time you rank up as well as getting Shift codes (see Gearbox Software's website for more info). One way to spend these points is from the menu select "Arsenal Upgrades" and a weapon you have unlocked. Upgrades available for purchase are highlighted blue with a number letting you know how much the upgrade will cost. Normal progression will require Rank 31 to have 30 points to spend and you will have earned a high enough rank to purchase the upgrades needed for the achievement.

I Heard THAT25
Collect all 12 Audio Logs (3) 

For the video guides, use THIS THREAD.

These look like small laptop computers and highlighted in a light blue color when you're close. Unlike dog tags and legendary weapons, any player who activates one of these during a co-op campaign will save it for everyone playing. Again, you can check progress the same as legendary weapons, except you press again to see the audio logs. There are 12 audio logs located in the following levels:
Level 1- 1 total (Request for Re-assignment)
Level 2- 2 total (RE: Request for Re-assignment & RE: RE: Request for Re-assignment)
Level 4- 1 total (Please Mom...)
Level 6- 3 total (Supply Requisition Order, Origin Construction Status Report, Evacuation Notice)
Level 7- 3 total (Xenomorph Lifecycle Notes, Hale Autopsy Report, Security Concerns)
Level 8- 2 total (Queen Progress Report, Origin Status Update)

Entry Prohibited20
Kill 10 Xenomorphs that are using vents (4) 

"Vents" are a very broad definition apparently. Any opening that aliens are exiting from counts toward this achievement. I had this finished before completing mission 1 on recruit. If you're not a good shot, use the grenades and the grenade launcher (pressing  when using the pulse rifle) as soon as aliens appear in rooms along the floors and walls.

Let's Rock!20
Kill 10 Xenomorphs in a game with the M56A2 Smart Gun (4) 

The M56A2 Smart Gun can be found in Mission 4 (No Hope In Hadley's) during the sequence with the sentry turret (For "Need a Deck of Cards?" pickup and place this turret for the achievement. Can be done in co-op too.) Use the smart gun to get 10 kills (easier on solo campaign) and restart checkpoint if necessary. This unlocks after you've killed 10.

Need a Deck Of Cards?5
Set up a UA 571-C Remote Sentry (4) 

See "Let's Rock" for info in campaign. In a private Survivor match on the map "Condemned" (as a marine) as soon as you spawn there will be a nearby computer to hack. This will give you the turret which will allow you to place it for the achievement.

Micro Changes in Air Density10
Track 100 hostile targets with the Motion Tracker (5) 

This will come along your 1st playthrough on recruit. Remember to press  whenever you hear the "pinging" noise or when you see the "radar" prompt at the bottom of the screen. I had this unlocked before finishing mission 2.

It's a Dry Heat20
Kill 3 enemies with a single U4 Firebomb (6) 

Once the firebomb is available (Rank 4), select the grenade by holding  and pressing left on your left analog stick to highlight it when you release . The firebomb grenade launcher doesn't work for this achievement and sometimes the soldiers count, but not every time like they should. I think "enemies" should've said "aliens" or "Xenos" to make this easier. In any case, there's multiple locations in the campaign where throwing the firebomb will net you the achievement. Personally I used mission 1 (Distress) when O'Neil needs to be defended while cutting open a door. Restart checkpoint gives you multiple attempts to make sure at least 3 catch fire from one grenade toss.

Eat This!10
Kill a Xenomorph with a shotgun at very close range (11) 

During your first encounter with a group of aliens on mission 1, they will try to melee you (or Keyes). You can either shoot it with your shotgun just before it swings with  or first press your right stick to melee it and when it is stunned, shoot it. You can even time the melee where you will go into an animation sequence that kills it with the shotgun automatically. All methods work well for this achievement.

Coming Outta the Walls!10
Kill a Xenomorph climbing on the walls or ceiling (2) 

You will likely unlock this while attempting the method for "Entry Prohibited." Once again, I had this finished before the end of mission one. Shoot any aliens on the walls or on the ceiling (more often on walls) to get this achievement.

Secreted from What?20
Kill 5 Spitters without being damaged by acid (6) 

If you're attempting this in multiplayer, it must be in one match. It's not cumulative. This is really easy in a private 1 vs. 1 Team Deathmatch. Have your friend spawn as a spitter and quickly find each other so that you can kill him/her 5 times without taking any damage. If attempting this in campaign, mission 6 has a cave where these are. Use long range scopes to take out five. If you take damage just restart checkpoint.

No Offense20
Melee a Lurker that is pouncing towards you (4) 

Another achievement that is easily boosted in a private 1 vs. 1 Team Deathmatch. Have your friend spawn as a Lurker and meet at a open area (preferably a long hallway). This is about timing. The further away the Lurker is, the easier to react. Melee the lurker before it hits you with a pounce. The player controling the Lurker holds down  and will see a trajectory of where they will pounce. Aim this at the person trying for the achievement and release when they're ready. May take a couple of tries. There's a few campaign locations for these, but perhaps the best is mission 4, at the very end. Before the final door is unlocked, you must kill 3 lurkers that spawn one at a time. Restart checkpoint if you can't get the timing for this achievement down before the 3rd one is killed.

Arbitrarily Exterminated30
Kill 2179 Xenomorphs (31) 

After completing the game on recruit, UBA and finishing challenges, load up mission 4 (No Hope in Hadley's). When you first get the SmartGun, start killing in the tunnels and restart checkpoint when it's cleared out. You can get about 20-30 kills every few minutes. This seems to be the fastest method so far.

Anytime, Anywhere20
Kill a Crusher without it damaging you (5) 

A quick way to boost this in multiplayer is on 1 vs. 1 Team Deathmatch (map is Last Hope) and have the player using the alien become the Crusher. This is done by receiving a prompt to "press  unleash the crusher" when near a "hive" location. There are 2 along the path under the bridge in the middle of the map. To the alien, these will have a real bright yellow/green highlight to them (one located next to a forklift). Once transformed, the marine (who's trying to earn this achievement) must shoot the body (explosives speed this up to) to kill it. Remember the head is nearly invincible and your friend shouldn't damage you for this achievement.
Towards the end of mission 9 (Hope in Hadley's) there is a fight with a crusher if you'd like to attempt this in campaign. Once it appears, find high ground (hill, slope, crate) to avoid damage from it. Kill using your explosives and shooting the body. You must get the kill for this to count. Use restart checkpoint to your advantage if you're damaged by it or don't get the kill. Remember the head is invulnerable. This is easier in co-op to have someone distract it. The AI can still steal your kill, so be aware.

Be sure to listen to the explanation while watching the video from azGRIMES:
 

Love at First Sight10
Survive a Close Encounter with a Facehugger (27) 

When a facehugger (the tiny spider looking things) attempts to.. umm.. hug your face, you will be prompted to press  rapidly until you've freed yourself from its grasp. Once you've done this, feel free to shoot it because the achievement will pop. I unlocked this in mission 2 rather early on recruit.

... But No Cigar20
Rescue a teammate from a Close Encounter (8) 

This can be done in a co-op mission or in multiplayer. In co-op, you can easily have this by the middle of the second mission. The first mission, an alien can attack your partner and start a grab animation (where they're about to use their second mouth to bite them). Shoot the alien point blank with the shotgun for the achievement. In the 2nd mission, you can shoot a facehugger while your friend is pressing  from a close encounter for the cheevo as well. In multiplayer, when a teammate is pinned by a lurker, shoot or melee it before they're killed for the achievement.

 
Secret Achievements
 
Easter Egg5
Find the Easter Egg (7) 

Early in mission 2, keep an eye on the walls to find a keypad. After pressing  to enter a code, it will unlock a door you recently passed that was locked (it didn't even have a solid red light). Once you enter this room, the achievement will unlock.

I’m Happy to Disappoint You50
Complete Stasis Interrupted on Ultimate Badass (11) 

Story related and cannot be missed.

It’s not too different from the main game’s difficulty. It’s easier in co-op like the main campaign. The final section of the DLC is the hardest part. Make sure everyone stays together because it is very easy to get swarmed.

We're Still Collating30
Find All Stasis Interrupted Audio Logs (1) 

There are 10 audio logs spread through the DLC’s 4 levels.

Level 1
- After hiding in the locker, it’s in the vent you use to flank the turret
- A while after the first audio log, It’s found on the counter in a lab before going into the room where you unlock “I Only Need To Know One Thing”

Level 2
-After Hicks uses a computer at the start of the level, a door opens on your right. The audio log is on a desk at the top of the stairs.
-On the left in the locker room. Shortly after passing through the library.

Level 3
-After leaving the caves, you will end up running through a broken fence. You will will see a building in front of you with enemies running out of it.
-After the last audio log, you will be on a path that forks. Take the right path that goes up and it's right in front of you on top of a box.

Level 4
-On the left side of the room at the start on the floor.
-After going through the part of the cave that is lit up orange. It's on top of a box. Hard to miss.
-In the first gas room. It's up the stairs on the counter.
-In the second gas room. Also upstairs.

I Don’t Got All Day20
Sever the umbilical without missing a shot 

About 3/4 of the way through the 2nd level, you will take control of a gun and be told to shoot the umbilical holding the two ships together. Hold until the gun is charged and release it over the red X. Do this a total of 4 times without missing for the achievement. It's pretty hard to mess this up.

They're Dead, OK? Can We Go Now?20
Kill all the Lurkers in Sulaco engineering 

At the end of the 2nd level, your objective will be to refuel the skiff. While doing this part, there will be between 3-5 lurkers that run in and out of the vents depending on the difficulty you are playing on. Just stay in the area and kill them until the achievement unlocks.

Now What Are We Supposed To Do?20

It's The Only Way To Be Sure20
Destroy all samples in the labs of the Queen module 

The wording of this achievement can be confusing. This is done during the fourth level. You do not have to destroy any eggs or anything else in the first half of the level. The opportunity to unlock this achievement happens in the rooms full of gas. When you enter the rooms, look for test tubes holding eggs, chest busters, and face huggers. They will be on pillars standing level with your face and easy to spot, or will be hanging from the ceiling above operating tables. There are a few eggs in glass chambers that require you to hit a button to destroy them with fire as well. Just make sure to clear each room out before leaving it.
