What happens when when you throw some Portal into Mario? Well, you might just get one of the most awesome crossovers to hit the net. In the fan made game Mari0, you take the normal role of Mario, but with a little twist. The portal gun from the Portal series is added into the game, allowing Mario to warp from one location to another, transport enemies out of the way, and to just have fun with physics.
