I know I'm a bit late, but even with all the new changes in the game, it's still not good.
The only reason this game isn't a one star is because the campaign mode and zombies is pretty good. Aside from those, multiplayer brings down its reputation. Movement feels sluggish, bullet velocity sucks and makes me seem like I'm lagging, and SBMM is a total joke. You can be a level 15 going 25-5 and then next game your facing max prestige no lives. Maps aren't anything special either, the DLC is the only thing somewhat keeping it alive. Definitely the worst Black Ops game, and I suggest sticking to MW if you still have it.
