Alien versus predator is a video game with hundreds of diehard fans. It is a combination of science fictions greatest creatures, Aliens and Predators. It also contains marines; all three known as hunter, survivor and predator. Effects like flamethrowers, rifles and pulse rising sounds spice up the game. Aliens and predators differ tremendously. Being an Alien is a bewildering experience. Dashing at preys or scurrying on walls. It is only for the sharp-minded. Predators end up trying to defeat aliens and marines. Being a predator seems more serious than it is, you require diversion tactics, and Multiplayer tournaments consist of different quests of victims allowing eighteen players to play at once. Each mission is for four hours. This game turns science fiction alive giving the most realistic experience of being one of these creatures. The game is interesting and time killing as well, enjoyment is definite and the battles are wonderful to play.
