Get to the dropship to escape the Sulaco (part 2) | Mission 3: Sulaco Falls A: CM Guide
Last update: 11 May 2016
Use the newly unlocked passage and equip your best weapon against Xenomorphs (my recommendation is the regular or tactical shotgun), because soon you'll be bumping into them. With the help of your teammates the battle should go pretty swiftly. Use the motion tracker if needed and above all else don't let the aliens anywhere near you.
Your need to get to the spot where there is a hole to jump into; you'll land in a partially flooded corridor. Follow your teammates and you'll reach a ramp, together with a new door on the right. Where you're on the partially demolished stairway, measure your leaps carefully. Try to land on the gallery shown on screenshot 1, because there are supplies as well as Dog Tag from screenshot 2 (PFC E. Greenlief) left there.
Jump down to the bottom of the stairwell and move forward, past a room with a dead soldier. There will be some new Xeno encounters in the next area, illustrated above. Use the flashlight to lit the darker spots. Check out the ceilings as well and side walls to prevent the aliens from performing a surprise attack.
If by any chance you fall down to the bottom level, find a ramp to go back up. Regardless of the path, reach the passage you see above. Turn left, but be ready to take down some new Xenomorphs. The steam will obstruct your vision, making it harder for you to locate the aliens, so it's better to keep firing a bit longer than usual.
Continue onwards, but keep looking around for collectibles. After reaching the large hangar bay, find the only available passage leading to the next location. Watch out for a single Xenomorph; take it down as soon as you open the door pictured above.
Move forward and soon you'll reach a tunnel where some mercenaries should be fending off Xenomorphs. Take this opportunity to shoot the enemies from a larger distance, using a good rifle and, if possible, the grenade launcher.
There won't be any new enemies in the next tunnel, you'll only have to reach the hatch (no need to hurry, too). Find the elevator you see on the screen. Wait until your teammates step on it and run it to reach the upper level.
There, turn left and check out the area near one of the large containers to find the above Dog Tag (Cpl T. Ashley). Head for the door leading to the hangar bay where the dropship is, listening to new orders from Reid in the meantime.
