Borderlands 2 has gone to certification, which is the final step before the game can reach gold master status, which would make it ready for pressing.
The developer also took the time to announce the 5th class, called the Mechnomancer, a perky red-headed goth chick with a knack for robots, which will be available a few months after the game's release. The Mechnomancer will be free to members of the Premiere Club, which can be joined simply by pre-ordering the game.
Joining will not only allow players to download the 5th class, but they will be rewarded with some weapons, a rare item, and the Vault Hunter's Relic, which increases luck in finding rare gear.
Borderlands 2 will be released on PC, Xbox 360 and PlayStation 3 this coming September 2012.
