Comanche was an SNES game developed by Novalogic in 1995. It was a port of Comanche: Maximum Overkill, which was released in 1992 for MS-DOS.
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, and 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, and speed issues since the game was seemingly too technologically advanced for the SNES to actually handle. No ROMs have been found of the SNES port so far, only footage and some pictures remain in existence.
