User Summary Initially just called RealTime Software, this new publisher entered the Spectrum market with an instant hit, a wire-frame tank battle. Using simple wire-frame graphics helped get around the Spectrum's simple colour schematics, but also made the game very fast. This release was seen as cutting edge at the time, and encouraged more publishers to adopt simple colour techniques. In the game, you drive a futuristic tank around a random landscape, shooting enemy tanks and UFOs.
