Too easy. Short enough not to break your keyboard. Too much hipe for nothing special. Serious Sam was better.
You can have a maximum of two guns on you at any given time. Yes, aliens and three titted babes are fiction but we really have to make him look human just by nerfing his stash.
(spoiler) You have to find a vibrator in the game. Really? Is that all they could think of?
Crysis 2 beats the **** out of this game with his hand tied behind his back, and I found Crysis 2 to be too long and particular repetitive (just to clear the water).
COD Black Ops had the most intriguing Single Player campaign I have played in a long time. And it comes with a real Multiplayer.
Mass Effect 1&2 just make this game look like a pre-alpha of a good game.
I have to admit i liked a few things about it, but those pale in comparison with the overall experience.
Too bad Steam games can not be re-selled.
