I couldn't find a topic on it, so here's my review.

Pros:
Creative use of terrain makes for interesting tactics.
Some of the weapons were neato, especially the vortex nade.
Good Graphics.
Cons:
Fights get repetitive fast.
Despite the fact that the enemies could have been hugely creative thanks to the premise of them being genetically altered, there were only a few units, and the biggest differences were their guns.
GLITCHES. The two best words to describe this game are RELEASE DATE. There were lots of bugs, and they were stupid ones. Sounds would vanish, once my shields ran out and flatly refused to recharge until I restarted the level, often I would complete an objective and nothing would happen, another chance to restart the level.
Certain enemies were stupid. One could only even be damaged with headshots, one shoots these stupid sticky green things that blow up, and then there's cheetahs. They are so lame. They teleport, but are just as tough to kill as any other enemy, and the fact that they always come at you in groups means that you're constantly getting shot and as soon as you get cover they teleport behind it and shoot you before your shields recharge.
Kinda stupid story.

All in all I think it's a good idea that translated poorly into a game because they rushed it and didn't smooth out the wrinkles. I suggest renting it if you feel like you HAVE to play it, but I wouldn't recommend buying it because there are NO multiplayer matches. No one plays it online. 5/10.

Haven't played it yet but I've heard mixed reviews on it. Some say its good others say its not that great. Gameplay video's look cool though.
