Guess what, guys? There's going to be a second Borderlands game.

2K officially announced today that the sequel to Gearbox's breakout action role-playing shooter is very much in development, and will be headed to the Xbox 360, PlayStation 3, and PC in fiscal 2012 (translation: sometime after April next year).

In addition to the basic announcement, Game Informer revealed Borderlands 2 as its September cover exclusive, dropping a few details on what we can expect from the sequel.

Don’t expect just a couple bazillion more guns this time around. Gearbox is introducing new and more diverse environments, smarter and more powerful enemies, and an improved mission system capable of delivering a better story.

Borderlands 2 will get its official live debut to the world later this month at Gamescom in Cologne, Germany, and will also make its way to PAX Prime this year. Anyone heading to either of those shows that feels like letting out a big, honking squee of excitement right now will be forgiven for doing so. Just, you know...clean up your mess afterward, okay?
