Let me start by saying that I never got around to playin' MW2, and don't know what was added in that one, but I love the added features this one has over the first one. Like choosing your killstreaks. SAM turrets, C4 wired RC cars, and unleashing a pack of deadly hounds on your ass is sweet as hell. Adding in different types of weapons like the tomahawk, ballistic knife, and crossbow were interesting, not that I use them much. The contracts are new to me, but I usually forget what I'm suppose to do to complete them once the round starts. I think it pretty cool that they let us make our own emblems to place on the guns. I noticed that they got rid of the perk that allowed you to drop a grenade once you died. I thought that was a good choice since it wasn't realistic to pull the grenade pin after death, and so many people were getting kills that they didn't really work for. It's true that there are a lot of campers in this one, but you can't camp for too long seeing as how you can be flanked anywhere on the level. Plus, once you die you can see where they were when they killed you and go there to take them out once you respawn.
