Realtime Games Software

"Realtime Games Software Ltd. was a British computer game developer, founded in 1984 by three Leeds University students Ian Oliver, Andrew Onions, and Graeme Baird. Their first game, 3D Tank Duel, was a wireframe graphics game, in the style of Atari, Inc.'s Battlezone arcade game, for the ZX Spectrum. This was followed up with Starstrike 3D, a game based on Atari's Star Wars arcade game. Carrier Command was published in 1988. The company was also involved in porting Elite to IBM PC compatibles and Starglider to the ZX Spectrum." - Wikipedia
