Nintendo has released some new details for the Challenge Mode and Coin Battle in the upcoming Nintendo Wii U title New Super Mario Bros. U that you can find below:
Challenge Mode: Challenge Mode tasks players with completing specific objectives, such as clearing a course without touching a single coin or touching the ground. There are four single-player Challenge categories: Time Attack, Coin Collection, 1-Up Rally and Special (miscellaneous challenges). Boost Mode Challenges require two players, with one player using the Wii U GamePad controller and the other using a Wii Remote controller. Once players complete a Challenge, the game saves a replay of the action so players can show off their accomplishments.
Coin Battle: Up to five players can play together and compete to see who can collect the most coins. One player will use the Wii U GamePad controller while the other four players use the Wii Remote controller. The player using the Wii U GamePad controller in Boost Mode can place Boost Blocks to help grab hard-to-reach coins. Players can also use the GamePad to edit and customize the coin layout in courses found only in Coin Battle. The coin layout can then be saved and played by the players using Wii Remote controllers.
