Princess Peach has been cursed by a witch, causing Mario, Luigi, and Bowser to team up and track the witch to a nearby kingdom. After being ambushed, Bowser is separated from the brothers, and they continue alone in a strange land. They'll also come across many other classic characters as they journey on to the castle for help.

Mario & Luigi seems to provide the same visual and gameplay styles as Paper Mario, but with a twist. Now you can control both Mario and Luigi simultaneously and team them up for certain special moves. Screens indicate that outside of battles B will make Luigi jump and A will cause Mario to jump.

Little else is known about the title, but we'll be looking out for it on the show floor.
