From Wikipedia

Borderlands 2 is a 2012 action role-playing first-person shooter video game developed by Gearbox Software and published by 2K. Taking place five years following the events of Borderlands (2009), the game is again set on the planet of Pandora. The story follows a new group of Vault Hunters who must ally with the Crimson Raiders, a resistance group made up of civilian survivors and guerrilla fighters, to defeat the tyrannical Handsome Jack before he can unlock the power of a new Vault. The game features the ability to explore the in-game world and complete main missions and optional side quests, either in offline splitscreen, single-player or online cooperative gameplay. Like its predecessor, the game features a procedurally generated loot system which is capable of generating numerous combinations of weapons and other gear.
