I play with the one I got from FilePlanet. The multiplayer is pretty fun, though there's only one map available and limited weaponry. I want to get the full version someday and find out how the extended Alien life cycle plays. I like going at it with the Marine and a Pulse Rifle, but the Predalien stories and Predator tales of pwnage seem to be worth the full version.
Anybody here have the AvP2 multiplayer demo? I'm asking because only one of my friends has it, so I would like other people to play with. I would like the full game, by the way, but I don't think that I would be able to buy it anywhere else but the Internet.
