The fifth instalment of the popular Paper Mario RPG series will see Paper Mario jump off the page and form a superstar team of Mario Bros. to take on the only thing more threatening to the Mushroom Kingdom than one Bowser: two of them! When Luigi accidentally opens a mysterious book hidden away in Peach's Castle, he gets more than he bargained for when characters from the Paper Mario universe spill out of the pages and start running amok. Players must take control of the terrific trio of Mario, Luigi and Paper Mario to defeat Bowser and Paper Bowser and bring the Paper Mario characters back to their original world.Adding Paper Mario to their ranks means that Mario and Luigi have even more ways to explore, solve puzzles and take down any enemies foolish enough to mess with the Mario Bros. In a first for the series, players can now battle with Trio Attacks, as well as use Paper Mario's unique copy ability, allowing him to create duplicates of himself in order to bolster his attack power.
