Shadow of the Beast for SNES was never officially released. It's a port of the Amiga game, Shadow of the Beast by Psygnosis. The SNES version was being made by a company called IGS. Nintendo Power mentioned it being shown at Summer CES 1992 convention, and that it looked better than the computer versions of the game. A rom of the game exists, and it appears that the game is fairly complete. It plays similar to many platform adventure games like Castlevania or Zelda II.
