Based in Manchester, this company's focus was the Atari 8-bit line, although several games were ported to the Commodore 64 and some to the Amstrad CPC. Some early titles were published in the US by Datamost and (mostly for Atari) Dynamics Marketing in Germany, but later titles were mostly only released in the UK. They disappeared in 1987, shortly after the release of Leviathan, their sole 16-bit game.
