Description: Arm the emergency release and escape in under 2:30 on Sulaco Falls

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.
