For a short period of time Steam featured a page for a Borderlands 2 DLC titled Commander Lilith & The Fight For Sanctuary. It is supposed to prepare players for the arrival of the third installment of the game. Check out the description and screenshots captured by Resetera:
Return to the award-winning shooter-looter for a new adventure that sets the stage for the upcoming Borderlands 3. Sanctuary is under siege, the Vault’s map has been stolen and a toxic gas is poisoning Pandora. Fight new bosses, explore new zones, get new loot (including an entirely new tier beyond Legendary) and join up with Lilith and the Crimson Raiders to take on a deranged villain hell-bent on ruling the planet
Returning players can pursue an increased level cap of 80, while newcomers can automatically boost to level 30 and dive straight into the action.
The Borderlands 2 DLC is said to be free and will release on June 9th.
Borderlands 2: Commander Lilith & The Fight For Sanctuary will get a store page soon
