C'mon, it's not THAT bad.
When you really sit down and give this game a chance, there are some respectable qualities to the game, despite it being Original Xbox quality. Sure, it has poor graphics and sluggish gameplay, but it's definitely not the worst game I've ever played, you know?
The fact that you only ever start out with a rifle and pistol is kind of irritating, but the occasions when you get the assault rifle/shotgun/giant mortar launcher were rather fun imo.
The voice acting isn't terrible and the score is actually quite relevant. Audio-wise, it's pretty good. Except the melee thud. Terrible.
And as far as how fluid it is.. Well, it plays like a computer game on a normal household computer. Good, okay, and glitchy at times, but in the end, acceptable.
So come on guys, don't give this game too bad a rep. I'm sure the producers worked really hard on it and are probably very proud of it. For their first go at an Xbox 360 game, I'd give them a C. So for anyone looking to buy, rent, or borrow this game, give it a chance. It's not as bad as everyone seems to think.
