I thought the demo was a blast, the Alien is my personal favorite just because I got used to the wall-walk really quickly and can really zoom around the map at terrific speeds dodging attacks and catching prey unawares. The predator controls are a little more complicated, but once you get the focus jump mechanic down it gets easier. Marine is frustratingly difficult to play because any hit sends you reeling and helpless to resist a grab and execute move. Even worse, you tend to spawn in the immediate proximity of opponents who then quickly dispatch you before you can even get your bearings.
All around I'm not disappointed at all, I think the attack / counter mechanics are really novel additions to the franchise. I can't wait for the full game so I can hone my skills better in single player before taking it back to the arena.
