Pretty awesome so far. I haven't touched the campaign or zombies yet, but the multiplayer is so much better than MW2 it's not even close. The maps are better, it takes longer to kill someone (which I like), the new game types are AWESOME. My favorite is the gun game (you start out with pistol and move up to a different gun after every kill, first one to kill someone with all the guns wins). Also, the killstreaks are more balanced. First, one killstreak doesn't count towards the other. For instance, if you get three kills, then kill someone with the RC car (a reward for three kills in a row), that doesn't count as your fourth kill in a row. This makes it harder on the "campers" to rack up kills so they can eventually get to the chopper gunner, etc. I love it. It is also the most in depth multiplayer.....ever. There are so many ways to customize your guns, killstreaks, perks, etc. Also, the leaderboards are more in depth and you can sort by each game type. You also have to buy your upgrades, new guns, killstreaks. I like this aspect too. So far, it's pretty damn good!
