Batman: Arkham Asylum was one of the most beloved games of the last generation, but Nintendo fans never got to experience it. Warner Bros. and Rocksteady never opted to release the game on Wii, but a prototype version was actually up and running at one point. Red Fly Studios had a knack for porting games to Wii, including Star Wars: The Force Unleashed II and Ghostbusters, and they even gave Arkham Asylum a shot.
It's definitely a steep decline in quality from the real game, but considering the hardware they were working with, it's pretty impressive that they were able to whip this up in just a few weeks. In addition to the Arkham Asylum footage, Red Fly Studios also shared prototype footage from Wii versions of Devil May Cry and Dig Dug. You can check out all of these never-released projects in the playlist above.
