Pre-order Borderlands 2 for Xbox 360, PlayStation 3, or Windows PC at GameStop in the United States or EBGames in Canada and you will receive the exclusive Creature Slaughter Dome, where you can “face off against the toughest monsters in all of Pandora.”

Doing so will score experience points and gear which you can then bring back to the main game. “Endure the battle and you will receive numerous rewards,” one of which is presumably Moxxi’s Rocket Launcher, shown in the image above.

Borderlands 2 will be available on September 18th, 2012.
