Nintendo of Europe revealed that the newest Mario & Luigi RPG, Mario & Luigi: Paper Jam, will be released in the region on December 4, 2015. The game was originally set for a worldwide release in early 2016, but it has been brought forward to December in Japan and Europe. It is not yet confirmed whether the North American release will be brought forward as well.

Mario & Luigi: Paper Jam sees the Mario & Luigi series crossing styles and elements with Paper Mario.

The game is being developed by AlphaDream exclusively for Nintendo 3DS.
