Players work together using four different classes of characters to complete quests, gather loot, and trade items. All three systems support online co-op. Local co-op is available on the console versions.
Set between Borderlands and Borderlands 2, you'll play as four all-new character classes fighting alongside Handsome Jack, witnessing his transformation into the ruthless tyrant you loved to hate in Borderlands 2, and assisting with the rise of the Hyperion Corporation. The signature shoot-n-loot gameplay of the Borderlands series expands with the addition of low-gravity and oxygen-powered jetpack combat, the icy "Cryo" elemental damage type, the deadly laser weapon class, and new vehicles to help you explore the diverse lunar landscape.More Info @ PCGamingWiki
