Borderlands

In a distant future where mega-corporations colonize and strip-mine entire planets, four mercenaries known as Vault Hunters arrive on Pandora, a lawless frontier world abandoned by the corporations that once exploited it. Drawn by legends of an alien Vault containing priceless technology left behind by a vanished race called the Eridians, they begin piecing together clues to its location with guidance from a mysterious entity known only as the Guardian Angel. Standing in their way is the Crimson Lance, a private military force deployed by the Atlas Corporation, which seeks the Vault's power for itself. As the Vault Hunters collect the artifact fragments needed to unlock the sealed chamber, they learn the Vault can only be opened once every two hundred years, and the next opening is fast approaching.
