A great achievement have just been made ladies and gentleman, Stabyourself have completed development of Mari0, a Super Mario Bros. and Portal hybrid game and the best thing is; its free. Its available for the PC, Mac and Linux.
The game is a complete recreation of the original Super Mario Bros. game with a slight difference, the Italian is sporting a portal gun.
The game features, a level editor, 33 hats for Mario to wear, 4-player co-op and many more great features. If this hasn’t gotten you excited, then you are dead to me.
