Ever since you left that last planet, you've been bothered by eerie sounds coming from somewhere in the hull of Nostromo, your giant transport cruiser. After setting the ship's controls on autopilot, you descend to have a look.
Yow! Every hallway in the entire maze-like hull has been lined with the grotesque eggs of some gruesome space creature. Quickly you sprint down the corridor crushing the eggs as you go. Then you see it! A hideous being with jaws like a beartrap. You run away from this brutal beast, not wishing to end up as an intergalactic snack. You turn a corner and stare unbelievingly. Another Alien is just ahead.
Don't bother calling for help. Remember, in space, no one can hear you scream!
