Action Gamemaster (unreleased video game system and line of games; 1993)
Active Enterprises was a video game company located in Miami active between 1989 and 1994 (when they went out of business). The company infamously created Action 52 and Cheetahmen II, two games which are considered to be among the worst video games ever made.
Following the release of Action 52 on Sega Genesis, Active Enterprises had plans to create a handheld video game console called the Action Gamemaster, named after a character from Cheetahmen. It would have had full compatibility with NES, SNES, Sega Genesis games, as well as CD-ROM titles that could be played via separate adaptors sold in stores. It would also have had support for its own line of exclusive games. Other features would have included a 3.2″ color LCD screen, TV tuner, built-in battery charger, and a cigarette-lighter adapter for cars.
Active Enterprises made an appearance at the 1994 Consumer Electronics Show to present their future projects, including a third Cheetahmen game simply titled Cheetahmen III, a SNES port of Action 52, and another game called Sports 5. None of those products were on display at the convention, however.
It appears that the console had minimal work done on it beyond the concept, and there are no known prototypes of it or its line of games to this day. However, it can be assumed that the product would have been expensive, bulky, and a generally poor device with low battery time due to its energy consumption.
