Played both a Predator and a Marine, It was somewhat fun although I was clinging to everything when I didn't want to. I had most fun playing as the marine. It was fun always looking on the walls and behind me blasting away when I thought something was there. I thought it was pretty fun as a marine; very challenging as the xenomorph or predator. The Predator controls I wasn't to keen on when it came to using the wristblades. The map looks good and a lot of the times I got caught off guard by people playing the Alien, made me jump a few times if I'm honest. I would of enjoyed it a lot more if I'd of gotten used to the controls a little more. Overall the little time i played it it was good, but a little slow. Can't wait to play the full version of the game and I feel that the demo should of included samples of the main campain game to IMO.
