I've only done multiplayer on it so far due to lack of time, but i think its pretty good. up to mw2? i dont know yet. what i do like is that the kill streaks arn't overly powerful, and they do not compound your kills torwards new streaks. (getting a kill with a killstreak doesnt add to the count) also i love the fact that the noobtoob was powered down considerably. worst part about it is that i found a facination with the rc car killstreak and end up focusing more on how many of those i can get and having fun with them.
