2K game disc. Developed by Gearbox Software. The action first-person shooter game is the first game in the critically acclaimed Borderlands series. The game features the ability to explore the in-game world, and complete both main missions and optional side quests, either in single-player or online cooperative gameplay. The game itself is rendered in cartoon-style graphics, to provide greater detail on weapons and environments, and was inspired by various action role-playing games of the time, such as Ultima and Diablo.
