In a third-party release schedule for Wii U, Nintendo dropped additional details on the impending Rayman Legends demo. Pegged as arriving late this month, the demo will contain the game's full online challenge mode.
According to Nintendo, we'll be able to play four levels, one of which, "Murfy's Dungeon," is exclusive to Wii U. (Yes, really.) Of course, Ubisoft will put out extra challenges on a daily and weekly basis -- this is a challenge mode, after all -- though I'm not sure how long such a thing can hold our attention. The September 27 launch isn't exactly right around the corner.
