Blizzard has released the Liberation of Undermine raid overview which will launch on March 4th!
Liberation of Undermine Raid Guide
Things are heating up in Undermine and the cartels are ready to take the battle right to the heart of Gallywix’ stronghold in the Gallagio. Players will encounter eight new bosses— including the Chrome King Gallywix himself—as they fight their way through the glitz and glam to get straight down to business.
