From GameWatcher: “Borderlands 3s fourth campaign DLC has just been announced, and it brings back Borderlands 2’s Psycho class character Krieg… as an NPC.
Named Psycho Krieg and the Fantastic Fustercluck, the add-on is launching on September 10th and puts players inside the mind of Krieg to find out the reason for Psychos’ deranged mentality. The mind trip is the idea of scientist Patricia Tannis, who believes that the signature lunatics have been driven insane by the knowledge of a mythical place called ‘Vaulthalla’.”
