Nightmare Circus is a platform video game developed by Funcom and published by Tec Toy for the Mega Drive.

On opening night, the circus was burned completely to the ground by its shady and villainous operator, the Jester, who intended to cash in on an insurance policy.

Many years later, a Native American named Raven, who had lost relatives in the fire, goes to investigate the location where the circus was held, and where supernatural events have been reported.

[2] In the game, Raven must go through multiple levels of the circus environment using various fighting moves to destroy enemies.

[2] The game's intended North American release in late 1995 was indeed cancelled, though it later appeared in that region for the Sega Channel.
