Forgotten Worlds is a side-scrolling, 360-degree rotatable shooter that was released on multiple platforms in the late 1980s and early 90s. It features two floating soldiers sent to an alien planet to defeat a being known as Bios. The game was originally known as Lost Worlds in Japan. It is also known for being the first Capcom Arcade game to use their CPS-1 board.
Forgotten Worlds was originally released in the Arcades on July 1988. It would quickly be adapted for the home computer market, such as the Amiga, C64 and Atari ST, by US Gold. Other console versions would follow, including a Master System and Genesis version by Sega and a TurboGrafx-CD version by NEC Interchannel. It was recently rereleased on Wii Virtual Console in North America on November 17, 2009.
