This game is known in Japan as "
Warzard". It saw a very limited release in the United States.
Red Earth is the first game to run on the Capcom Play System III hardware (CPS III), the first Capcom system that uses a CD-Rom instead of expensive EPROMs to hold the game data (about 50MB). When starting a cabinet with a new CPS-3 game the first time, the hardware needs 25 minutes to initialize the game. In fact it overwrites some flashroms with data from the new CD. This procedure allows the game later to startup as fast as it would normally run from regular EPROMs.
The character Leo was inspired by Conan the Barbarian.
