Lol. :P Play legit. It's much more fun when you don't lose twelve perms. / Or, make a bunch of hacker accounts and get an over 9000.0 KD.
Hehehe, over 9000 reference.
Now on topic: if you just check the combat arms section, there are a couple of pubs that work. However, they all have features which will pretty much get'cha banned. So like Aeronyx said, play legit.
