In the early 1980s, Artic Software, also known as Artic Computing, was a software development company based in Brandesburton. The company's first games were for the Sinclair ZX81 home computer, but they expanded and were also responsible for various ZX Spectrum, Commodore 64, BBC Micro, Acorn Electron and Amstrad CPC computer games. The company was set up by Richard Turner and Chris Thornton. Charles Cecil, who later founded Revolution Software, joined the company shortly after it was founded, writing Adventures B through D.
Initially packaging and distributing games themselves, some titles were picked up by Sinclair, who repackaged them under the Sinclair brand.
