From Press Release:
RAGE 2’s first expansion, Rise of the Ghosts, is available now for PC, Xbox One, and PlayStation 4. The sadistic Ghosts have made their way back to the wasteland under the leadership of a mysterious new villain, Iris. Spreading their nanotrite-infused influence while attempting to lead the world into a so-called brighter dawn, the Ghosts are a crazy force to be reckoned with. Explore a brand-new region, face a lethal new faction, and gain access to a new weapon and ability in Rise of the Ghosts.
Rise of the Ghosts is available on all platforms, downloadable from the in-game store for 1500 RAGE Coins ($15). Players who own the RAGE 2 Deluxe Edition automatically gain access to the DLC for free.
