I think the cm901 or ump45 unless the sub machine guns where like they where in Black Ops. -.-
As of right now the G36C because it's my favorite gun all around. However, if they made it suck in the game then I'll switch to something else.
since i played little of Mw2, i didnt get a good feel of any of the weapons, even though i know the weapons were tweaked a bunch. The Ak-47 will always be my baby though. thats the gun im probably going to max out first
i love Gun Game in black ops about i wish they did that in MW3
Famas and Mp5 , M4 for sure best guns
