Mari0: Mario meets Portal (2)
Back in April I posted a Super Mario Brothers and Portal mashup. The guys from StabYourself also saw this video and liked it so much that they decided to turn in a real game called Mari0. Besides the addition of Portals to the 1985 SMB game, they also added hats, 4 player online co-op and a level editor. Your can download the game for free at their website and below you can check out the teaser trailer.
