Action 52 is an unlicensed multicart video game compilation developed by Active Enterprises for the Nintendo Entertainment System. The NES version was released in 1992. The multicart consists of 52 games in a variety of genres, mostly scrolling shooters and platformers. The "featured" game is The Cheetahmen, which was part of Active's failed attempt to create a franchise similar to the Teenage Mutant Ninja Turtles. The NES version of Action 52 sold poorly and became infamous among gamers for the poor quality and functionality of its games; it is often considered to be one of the worst video games of all time.
