Played three matches in Crysis 2. Finding a game was a pain but that may be just early launch stuff. I didn't know they had an unlock system in the game. Looks similar to CoD system. They also had killstreak perk thing with exactly the same rewards at level 3, 5, and 7 (UAV, Orbital Strike, and Air Gunner).
I like sliding around and hitting people across the map. Graphics are amazing. Gameplay feels tight. The game speed is not as fast as CoD but not as slow as BC2. I think the speed feels just a bit faster than MoH.
