This game bears the same name as the b movie (this movie was about alien vampires that sucked life-force from peeps, which inturn made them vamps), but has nothing in common with it. I only mention this because I always read that the game was based on the movie. At any-rate, this is a solid game that is really hard. You fight your way through level after level destroying aliens (and bosses) until you face the Big Boss. I will not give anything away, but the ending wasn't great to me. That does not take away from the hours and hours of fun you will have with this game. It is one of the better "shoot them up" games you will find. If you can find it, get it. You will love it.
