Gearbox has confirmed its casual E3 mention to Joystiq that it plans to release Borderlands this October. A company representative told us today that it's looking forward to breaking new ground this fall when the "role-playing shooter with strong co-op and split-screen gameplay" is released. The rep also confirmed that the post-apocalyptic action game will launch simultaneously on Xbox 360, PS3 and PC.
Borderlands had been banging around for a while, then disappeared for an awkward period of time before ultimately reemerging – think: butterfly – with a new art style, which freshened up the title and removed it from "Fallout clone" territory. We'll have our E3 impression of the title up soon.
