Team Tac SnD boosting and also strafe run boosting you can rank up at least 8 times a game if you do it correct, prestige within two hours if you listen, and don't back out constantly.
I am looking for three more players who are willing to stay in the same lobby and rank up fast:)
All you need is a mic and two controllers i will do this all day if you want:D
