Hey guys, DeltaNumaris here to let you know of an unbelievable resource you have available.
I personally bought Call of Duty: Black Ops 2 on Steam.
But for those of you that didn't, there is a Free to Play Online Matchmaking on the internet.
Plutonium is a Website/Gaming Platform that allows you to torrent the Game (They provide the torrent) and once installed you can play BO2 Online with your friends or with other Plutonium Members.
