9. Short, Controlled Bursts (20G) — Defeat all Xenomorphs in the Sulaco hangar bay without them crossing your barricade
Location: Mission 1: Distress
Shortly after fighting your first group of Aliens you will come to the hangar bay. Your comrade will throw a grenade and blow up a dropship. After that you will have to defend him until he opens a door. Two AI controlled allies are standing behind a barricade. None of the enemies may get behind this barricade! It’s recommended to play on the lowest difficulty Recruit. Stay in front of the barricade all the time. Enemies are much more likely to attack real players than AI controlled ones. You might take a few hits, but the shotgun will kill all Aliens quickly. Once the door is open, fall back immediately!
10. Fire Drill (20G) — Arm the emergency release and escape in under 2:30 on Sulaco Falls
Location: Mission 3: Sulaco Falls
At the very end of mission 3 you will come to some sort of hangar. The relevant section for this trophy / achievement begins as soon as you enter this area. You have two minutes and thirty seconds to activate three switches and enter the dropship. It’s recommended to play on the easiest difficulty (Recruit). This allows you to rush into the enemy groups without dying. Use a shotgun to take them out while running to the next switch. After all switches are activated you simply drop down and go to the dropship. The missions will end here and the trophy / achievement pops during the next cutscene. Make a backup of your save game so that you can try it again without replaying the entire mission.
11. Mostly Come at Night… (20G) — Find Newt’s doll
Location: Mission 5: The Raven
In the beginning of mission 5 you will have to find a way out of the sewers. When you come to the section where sound-sensitive Aliens are walking around you should look out for a switch that powers up a generator. The aliens will run to the generator and explode. Newt’s doll is not far away. Look for three barrels near a yellow light. The doll head is sitting on one of these barrels.
12. Just a Grunt (20G) — Complete Hope in Hadley’s
13. No Need For Alarm (20G) — Complete One Bullet without setting off the alarm
14. Heavy Lifting (20G) — Defeat the Raven in under 1:10 on Soldier difficulty or higher
Location: Mission 5: The Raven
Make sure to start this mission on Soldier difficulty! Raven is an Alien boss at the very end of mission 5. You will have to defeat him by using the powerloader. Use the LT button for quick punches. Try to force him into a corner and keep punching very quickly. Sometimes the boss attacks you or runs away. The time is relatively short for this trophy / achievement so it might take a few tries. Be aware that the missions ends as soon as the boss is dead. Pause the game when you do automatically jump out of the powerloader and if nothing pops up reload the checkpoint. You might also want to make a backup of your save game so that you can try it again without replaying the entire mission.
