Tony Warriner is a video game designer, programmer and co-founder of Revolution Software. At a young age he started playing adventure games, when they were just text adventures. He wrote his first game, Obsidian, while he was at school and sent it to Artic Computing for consideration. Artic's director, Charles Cecil, loved the game and convinced him to license it to Artic, and then to join Artic as a programmer. At Artic he wrote, together with Adam Waring, Ultima Ratio which was published in 1987 by Firebird. In the same year he got a job at Cecil's Paragon Programming, where games from US publishers were converted to European platforms. When Cecil had left to work for U.S. Gold, Warriner started doing 8-bit programming for games. In 1988 he created Death Stalker, published by Codemasters
