This shooter game is based on the movie Aliens that did garner a lot of shrieks from the audience when it was first shown. The main reason why you recognize this game right now might be because you enjoy this shooter game as well. The game itself is set in another universe that is truly different from the earth that we know and love right now. The setting is actually based on the setting that was shown after the third part of the movie Aliens. If you would like to remember how well you have played the game before or you are only starting to play it now, making this your desktop background can be fun.
