Steel Force is an almost direct copy of the famous 1991 Commodore Amiga shoot-em-up, "Alien Breed"; released by UK-based software house, 'Team 17'. The characters movements and the game's grpahical stylings are almost identicle to the Amiga game.

Electronic Devices is now called 'Elettronica Video Games'. They are still based in their original location and now import arcade games into Italy.
