Lack luster gameplay and more bugs than an ant colony lead to an uninspired game.
Taken from the review:
I haven't played a First Person Shooter this bad since Turok Evolution. The game is certainly playable and you can see that there are ideas that if implemented well they could've worked out to be something interesting. In a holiday season as busy as this one with a lot of great FPS's there is no reason to buy this game. If I got this game for Christmas instead of Bioshock, Call Of Duty 4, or The Orange Box I'm pretty sure that fisticuffs would ensue.
