Crysis 2 is beautiful. It is one of the best looking games I've played on the PS3 and it really pushes the hardware to the limit.
That's about it. The game isn't very interesting except for its graphics. The game mechanics mimics the same as any other fps. The story is very much like Resistance: Fall of Man or any Hollywood block buster. The environments are good, but we've seen it before and it doesn't surpise anyone.
The game lacks in variety. There are very few enemy types and once you've completed the first 1/4 of the game you've seen them all. From there it is just more of the same. Luckily this game is not very long and it is possible to finish it before you've get bored to death.
I played this because I got it for free on my PlayStation Plus. I wouldn't pay a dime for it, but if you got some spare time and want some mindless bullet action, check it out.
