Good game and not as bad as they say it is.
I gave this game an 7.5 for being good but not great and it definitely has its Cons and Pros which are explained below.
Pros
------------
Graphics are pretty good.
Multiplayer is awsome (If you can find enough players)
Single Player is good for the Marine and Predator.
Trophy kills and Stealth Kills look cool.
Cons
-------------
Controls are horrible for the Alien.
Alien campaign is to drab and doesn't offer much.
Repetitive voice acting.
Campaign is to short. (Depending on difficulty)
Overall the game looks good and its worth playing if you can find it under 30 bucks, but beware of the controls for the Alien they WILL make you vertigo!
