Let me start off with the strong points:
The game has amazing graphics. The characters and scenery seem absolutely real and the story line is well planned.The variety of weapons is so expansive and the perk to be able to play though with unlimited ammo (once youve beaten it on the hard difficulty) is great too. The AI of your partner is awesome too, if you're in trouble just press B and they come straight to your rescue without little damage being inflicted on you.

The weak points:
For those of you that are really into first person shooters this game will disappoint you. Perhaps the hardest time I had with the game is the fact that you cannot move while shooting. Your character remains stationary while aiming and firing. I cannot begin to say how frustrating it was for me to be stuck in a horde of infected without the ability to run and cap them off one by one. Instead you're stuck in the midst of them trying to shoot one side when they're hitting you from the other. It drove me absolutely bonkers and eventually forced me to stop playing the game. It may not sound that annoying but once you play it you will catch my drift on it.

I give this game a 6 out of 10. Graphics and AI mean a lot, but they shy away when it comes to the controls and feel of the game.

As always, I will say try before you buy. But don't be surprised if you find yourself buying shortly after trying. This is by far one of the best Co-Op shooters I have played in recent years. That being said, I would recommend playing it as a Co-Op with another player instead of goin it solo.

Pros:
-Awesome Graphics
-Decent selection of weapons
-Challenging (but not impossible) Boss Fights
-Great Co-Op gameplay
-Can swap weapons/items with partner

Cons:
-CAN'T MOVE AND SHOOT/RELOAD SIMULTANEOUSLY!!! (My least favorite part of the RE series)
-Frequently run out of ammo
-Low limit of how much ammo you can carry
-Partner AI is weak and useless (hence the warning to play with a partner)

Other Thoughts:
-Controls take some getting used to
-May be better if you could switch between FPS/TPS modes

Summary:
Not without its flaws but overall an awesome game. Definitely worth a try.
