Wait until Keyes opens another passage. Once you're inside the corridor, get ready to take down the aliens that will show up from the room on the right. When it's clear, go inside, because the main corridor in blocked.
Eliminate further Xenomorphs, not forgetting the ones that will break through the small window on the left. Head for the next room. Here, start with the aliens that will show up right in front of you; then take care of the ones coming from the left corridor.
Backtrack to the main corridor and turn right. Take down a new batch of Xenomorphs and immediately follow Keyes, because pretty son this place will be crawling with unlimited numbers of aliens. Turn left at the fork and don't stop until you reach another room.
Turn around and eliminate a single alien that will be trying to open the door again. Check the room for supplies. In the meantime, Keyes will open the door to the hangar. Wait until he moves and follow him to the hatch where a group of marines is fending off aliens.
