Comanche was an SNES game developed by Novalogic in 1995. In this game, you control a helicopter through vast mountains with lots of combat taking place. The game was going to take full advantage of the Super FX chip, & a more advanced voxel graphics engine. It would've also included a way to play multiplayer through a link cable called the Super NES Game Link Cable, which also never saw a release. The game ended up not being released as Nintendo thought there would be no way to resolve the graphics, & speed issues since the game was seemingly too technologically advanced for the SNES to actually handle. However though, the game did get released for PC before a SNES port was ever commissioned. No ROMs have been found of the SNES port so far, & only footage, & some pictures remain in existence.
