Two disparate Mario worlds will collide in the newly announced Mario & Luigi: Paper Jam. Announced at Nintendo's E3 2015 Direct presentation, the game combines the RPG worlds of the Mario & Luigi saga along with Paper Mario.

The gameplay combines elements of both games, and you'll need the unique powers of both the physical and foldable forms to get pas puzzles and foil bad guys. The combat system seems to borrow elements of both the action-heavy overworld from Mario & Luigi, and the rhythm-focused combat from Paper Mario.

Paper Jam is due out Spring 2016.
