Nintendo have announced via their Direct that Paper Mario: Color Splash will arrive on Wii U later this year.
This is the first Paper Mario title to be developed for the Wii U, and is currently still in development prompting Nintendo to skip out on announcing a release date — we’ll get one “sometime in the future”.
Paper Mario: Color Splash takes place on Prism Island, which has been drained of its colour. Mario is equipped with a paint hammer and is taken with restoring colour to the island, including one example shown in the Direct that featured reanimating some whited-out Toads.
The game is due for release sometime this year.
