Crysis

What begins as a simple rescue mission becomes the battleground of a new war, as alien invaders swarm over a North Korean island chain.
Armed with a powerful Nanosuit, you must achieve your objectives by any means necessary. Become invisible to stalk enemy patrols, or boost your strength to lay waste to vehicles. An advanced AI controls your enemies, so play smart. One wrong move out here could be your last.
