Personally I've found all of the AVP games a bit lacking. AVP1 was innovative in its atmosphere and in the way the Alien plays, but that's about it. AVP2 is corny and really quirky. AVP(3) was just ridiculously linear and short. I think the only reason these games sold is the franchise.
This Aliens game would be much more interesting if it had more single player focus. But it sounds mostly like a game for L4D fans. There was also a developer interview video that I watched that had ridiculously thick fanboy service for Aliens movie scenes. Maybe that's magic for some people but I'd rather not relive movie scenes in a game.
