A few months ago I posted about a game called Mari0 that lets you play through the game Super Mario Bros. with the Aperture Science Handheld Portal Device. Back then, the game as still in development. But the suspense is finally over – Mari0 has been released! The game is a complete re-creation of the original game that also features a working portal gun, 4-player cooperative play, a level editor, downloadable map packs, game modifiers, cheats, full character color customization, and hats. Lots of hats. It’s also compatible with all operating systems and is open-source. The best part, however, is the price. The game is completely free! It’s a real blast to play and I suggest that everyone head over to the download page and check it out.
