Perfection.
The visuals are top-notch and among the best of ANY game on ANY system.
The cover system along with blind-fire was perfectly implemented into the game, along with the well-designed environment for a nice balance of close combat with long range fighting.
The COD style damage/recovery system is a perfect fit, (no fumbling around for health-packs and such) perfect for an action shooter.
The multiplayer has huge replay value and the online co-op is always fun.
Overall, I do not know how future iterations of this game will be able to top it. Actually, I dont care if it tops this one, I am looking forward for more of the same and I will be happy to hand over another $60 bucks for a great game like this.
