Game speed is too much for most. Specially if you're not used to a FPS speed like Quake. If you can hang with other fast paced games AVP shouldn't be a problem.
I played a new multiplayer mode Yesterday it was called Infestation, objective is to try and survive with a bunch of other marines, somebody in the group gets selected to start off as alien, colonial marines can work together or move as they please but its best to stay in a group. Once the Alien kills someone the marine that died becomes an Alien also, until all marines are wiped out or last CM survives and kills all aliens for one of the many achievements/trophies. Feels like the movie Aliens playing this mode, stick to the closed in areas on the map use your motion tracker to track aliens, the louder the beep the closer the enemy is. No preds allowed in Infestation. Damn I feel like watching the old Aliens movie now.
