The original Borderlands consisted primarily of desert areas, but the developer stated that adding more diversity was a "major goal".
VP of Marketing Steve Gibson revealed to Digital Spy in an interview: "There is a ridiculous variety of environments.
"There's going to be snowy areas, there's going to be hot springs, there's going to be grasslands, there's going to be cityscapes, there's going to be volcanic rim areas - desert areas, of course. You name the colour. We kept the art team very busy."
Gibson also stated that the variety extends to the enemies, adding: "We wanted it to feel like even when you're travelling through one particular zone that the style of combat you engage constantly changes. It's not just a constant, 'Here's this one enemy, here's how I defeat him, I'm just going to do this for two hours'.
"All of the enemies have their own reactions and their own attack styles. It's much more diverse now."
Borderlands 2 will be available for Xbox 360, PlayStation 3 and PC in September 2012.
