If you own a PS3, then this is a must-have.
Throughout the game you try to stop the chimerans in various ways at various locations around England. Because of Hale's infection immunity he gains somewhat super-human powers and basically sets off on mission all by his lonesome annihilating countless enemies. Many levels will be spent alone fighting herd of chimeran enemies, from the little to the massive. As you will have allies most of the time, they can die. And when they do, they don't come back. As any other FPS this game has the same elements; different guns, vehicles, and epic boss fights. Although, this was a fall back on the game, it's not very original. Another thing that bothered me about this game was towards the last four or five levels, the difficulty level increases dramatically, to the point where you will want to throw your controller against the T.V. The graphics are not up to PS3 capabilities but, it's one of the first FPS for the PS3 so why whine?
On the good side, the story is somewhat captivating enough to keep you playing, even when you should be doing other things. I found myself playing this game instead of studying for mid-terms. The voice acting could be better, and the game controls could be more fluid, as well as the physics. In this game, it seems when you kill someone they turn into a rag-doll whose gained five-hundred pounds. With replay value, this game has a "trophy system" built into itself. By doing certain tasks, such as killing four enemies with a frag grenade at once, will award you "skill points." Get enough of these skill points, and you can unlock different goodies, such as concept art, behind the scenes footage, and different skins for your online character. This game does, obviously, offer online play, which is very addicting. If you do not find enjoyment in the main game, then you will in the online play.
All-in-all, if you own a PS3, then there is no reason not to get this game. Even thought it's just like most other FPS, it is still very fun and highly addictive. By now you can buy it for cheap, AND with Resistance 2 coming out soon, it would be a waste not to own this game or at least play it once.
