The very definition of a FPS
Presentation: Graphics are beautiful and at a silky smooth frame rate. The sounds of the battlefield are clear and intense. You truly feel your in the front lines.
Gameplay: It is simply done right. The gunfights are just right with some very fun side missions such as playing as a sniper in a ghillie suit. The environment is design well with clear objectives. Enemy A.I. will push your limits at times especially at Veteran. Personally, I still finishing up Veteran and this is where I found the single flaw in the game in my opinion. As many who has played previous games in the series that enemies will respawn continually until you've progressed beyond a certain point. For the most part this isn't a problem even on Hardened but on Veteran some of the game's pacing can frustrate you beyond belief.
Multiplayer: Best online shooter available. Sorry Halo, I've moved on.
Replay: High
A must-play game for any PS3 or 360 owner. About as perfect as it gets
