A well executed FPS that is fun to play. The Marine campaign is great to play at night in a dark room, as it has its scary moments confronting Aliens popping out of the darkness. The Predator campaign is really fun. You have all the weapons from the movies and can take down hoards of aliens at a time. The Alien campaign unfortunately is let down by controls as it is hard to transition to walls and ceilings without getting frustrated at times. If you are a fan of Aliens or Predator movies then this game is for you, has an original plot that fits into the universe and all the glorious sounds from the movie. The marine rifle sounds awesome! A really great game.
