Science in the Mushroom Kingdom!

Two of gaming's greatest masterpieces are brought together to create a fantastic new twist on an old classic!

Super Mario Bros., a game that defines platforming, and Portal, one of the most-loved puzzle games, combine to bring you Mari0, a game where our favorite mustachioed plumber is given the famous Portal gun, and is off to tackle adventures old and new.

Take on the all the classic worlds you know, tricking and defeating your enemies with portals, or put your mind and the portal gun to work in brand new, puzzling levels. Even create and download custom maps made by other players!

Stomp a goomba, defeat Bowser, grab those mushrooms, place those companion cubes, think with portals! Adventure and puzzles await in Mari0!
