Note: This game port contains only 1 of the 3 scenarios in the original game. "The Reactor Room" scenario (nine marines vs. the aliens in their lair) lets you recreate one of the key battles from the 1986 science fiction/horror film. Marines can have very short life spans in this game, especially if they don't work together. Game play is fast and intense - does a good job of creating the sense of urgency felt when watching the movie.
