i think it is worth the 60 bucks. feel alot like cod1, that classic look to it, guns are more realistic. Great improvement over cod4, the maps feel great, lots of depth to them.
Best of no cheap kills, no across the room knifes and stuff.
the dogs are better than a chopper, they act as a second UAV, that tells the story behind those things.
artillery sucks, it has to be out in the open to kill you, but it can act as a giant stun nade.
