Glyn Williams and Michael Powell, the founders of Particle Systems, originally met at King Edward VII school in Sheffield. When the school acquired one of the first desktop computers in 1979 they were the first to experiment with it, and that meant designing and writing games.
After university, both independently moved into the UK's tradition of one-man "back-bedroom" developers. Michael produced titles such as Powerdrome and SubWar 2050, while Glyn was responsible for the Cholo and the seminal space-sim, Warhead. In 1996, in the face of ever-growing project sizes and budgets, it became apparent that a single man project was no longer viable; they decided to form a development company and Particle Systems was born.
