Super Mario Fusion Halo 2010

Super Mario Fusion: Mushroom Kingdom Hearts. Much like the legit Square Enix franchise, Fusion features a dimension-hopping Mario, and worlds based off of other video game franchises, including Halo, Sonic, Doom, Castlevania, Ghouls and Ghosts, Mega Man, and a handful of other Nintendo titles. Using familiar controls similar to those of Super Mario World, and a new gunplay mechanic using Covenant weaponry, this programmer has created a Frankengame that is definitely worth checking out.
