MariO is a brilliant and strange new creation you can find for download from Stabyourself.net. It’s a mashup of Nintendo’s classic Super Mario Bros. platform game with Portal. That’s right – Mario now has a portal gun, which he can use to transport between different spots on the level, and various puzzle points on the menu have been worked to take advantage of this new gameplay mechanic.
The free game comes complete with four-player multiplayer coop gameplay, a level editor and downloadable map packs. It’s available for Mac OS X, Windows and Linux.
I’d recommend grabbing it soon, because I can’t see Nintendo’s lawyers sitting down on this one for too long.
