Portal + Super Mario Bros = Mari0

What happens when you merge classic Super Mario Bros with the modern classic Portal? It’s hectic, it’s a ton of fun, it’s Mari0. Basically you get old school Mario re-imagined with a portal gun and a variety of Portal puzzles and mechanics. There’s also an insane four player co-op mode, level editor, and downloadable third party map packs.

Mari0 is completely free for Mac OS X, Windows, and Linux, download it from the developer below:

The game is somewhat maniacal but that’s what makes it fun. As expected, controls are a cross between Mario and Portal: Left-clicking a mouse will shoot the entry portal, and a right-click gives you the exit portal. Mario himself is moved around with either the arrow keys or the classic WASD triangle with spacebar as jump.

Grab the game now, or check out the video below if you aren’t convinced yet:

You might want to grab this quick though, as LoopInsight mentions, Nintendo probably won’t let this one stick around for long.
