In addition to the main playable characters, Murfy the greenbottle, who first appeared in Rayman 2: The Great Escape, appears as an assist character. Murfy can perform various actions such as cutting through ropes, activating mechanisms, grabbing hold of enemies and assisting in gathering Lums. These offer a range of levels in which co-operation is required to progress. In the Wii U, PlayStation Vita, and PlayStation 4 versions of the game, an additional player can control Murfy directly with touch controls, using the Wii U GamePad, the Vita’s front touch screen, and the Dual Shock 4 touchpad respectively. In single-player mode, control will switch over to Murfy during certain sections whilst the computer controls the player’s character. In the PlayStation 3, Xbox 360, Xbox One, and PC versions of the game, Murfy moves automatically and can be prompted to interact with certain objects with button controls. Other new features include sections where players can fire projectile fists at enemies and rhythm based levels set to covers of songs such as “Black Betty”, “Eye of the Tiger”, “Woo-Hoo”, and “Antisocial”.
