alien vs predator(what could I say more)
I love the way it gets to u, nice story, nice background music, quite scarry with the marine when hoardes of aliens come rushing to you( I could say that if u are the scary type or have a weak heart, don't plau this game, u'll die with your hands on the keyboard and mouse-just kidding)
I love the skirmish mode, that is where I spent most of the time I played the game, of course after finishing it with all the characters.
and for those out there that haven't played this game yet, don't think of the movie series, it has no corelation with them, and it's way better that the alien versus predator movies to
the game also has a nice multiplayer, great ways to hack and slash or to eviscerate your best friends(virtualy) if u have a grudge on them HA HA HA
