Playing this game in 3D was awesome, it simply looks amazing. But, Crysis isn't your typical run-and-gun style shooter. You need to be prepared to do a bit of thinking before you just rush into a fight.
The game is designed to have the player analyze the area first and then attack. Seems a little more suited for PC play with a keyboard and mouse rather than a controller due to all suit functions.
Weapons are pretty neat with the addition of the bow and such, but nothing too amazing.
Give it a shot if you're into FPS games in general and are looking for an alternative to a Call of Duty title.
