I think I would have liked this one a lot better if I had known ahead of time that it didn't really have a storyline...
I had a very hard time caring about what was going to happen next as I went through this game, probably because I always knew... after I finish killing these guys, I'll move to the next location and kill more guys. The characters were just a bunch of jocks, who didn't really have anything intelligent to say, and were never really developed. The only attempt at any kind of character history ***minor spoiler*** was that Marcus's father had a history of trying to defeat the enemy as well. But that was so underdeveloped that it would have been better off if they had just left it out, in my opinion ***spoiler over***. Anyways, the total lack of compelling storyline made it very difficult for me to finish this game, but I did it anyways, pretty much just so I could say I did. Hooray for me...
That being said, the game did have some redeeming characteristics. The graphics are amazing... seriously. It looks awesome. And the control scheme is really easy to pick up on and it makes sense (I was using the Xbox 360 wireless controller for Windows). The gameplay itself was actually fun. There were enough shootouts to keep you busy almost all the way through the game. It's an intense game, but like I chose to label it above, it's "all flash, no substance."
Now if flash is enough to really keep your interest, then this game will definitely be for you, but I guess I've come to expect a little something more from a game these days.
