Everything I said in another thread I take back now.
I have been playing this game for a few days now, and I have really enjoyed it. A guy I play MW2 with got Black Ops at around the same time I did. I guess you could consider him a pro, almost always getting MVP. He gets on Black Ops and totally fails without Aim Assist. I rofled so hard at him.
The only issue I have with this game now is that almost all of the maps are CQC. If you bought this gaming hoping to get good sniper shots, you might be a little disappointed.
Other than that, the gameplay is good, the Zombie mode is better than Nazi Zombies because it has more weapons, more zombies types, and more room to run around.
I would move away from MW2 completely, but Delta[SP4] only has MW2, so I still play it some.
If any of you want to add me, my GTag is "Ghost2147"
