The Xenomorph are fast, spit acid and are right behind YOU! The motion tracker is your only warning. No time to think, no time to catch your breath...RUN!
Can't see very far ahead in these air ducts. Hard to breathe. Face-huggers can be anywhere. Must find a Queen Alien. The closer you get, the more Aliens you find...better not have them find you first!
Just keep telling yourself, THIS ISN'T REALLY HAPPENING...IT'S ONLY A GAME.
