MotorStorm: Monument Valley
There were various times at which new liveries were available for download in Monument Valley. These including the Halloween scheme for the Castro Robusto, Holiday theme for the Castro Varadero, Chinese New Year Wulff Revo, and the Team liveries such as Big Eye Bunny, Quickfoot, Crazy Samurai and Numskull packs for all vehicles. There are also new liveries unlocked through the DLC packages that were previously AI exclusive. For example the metallic red & black livery for the Italia Vulcan and the Mute Bear livery for the Nord Viking are both unlocked through the Devil's Weekend DLC.
