Borderlands 2 isn’t content with the idea of being ‘just another shooter.’ A little bit Doom and a little bit Diablo, Gearbox Software’s “looter shooter” series marries fast-paced run-and-gun action with the ever-dangling carrot of sweet, sweet loot.

Read on for interviews, design documents, and forward looks at where Borderlands came from and what’s to come for the wildly popular series.
