Free Radical Design Ltd. was a British video game developer based in Nottingham. Founded by David Doak, Steve Ellis, Karl Hilton and Graeme Norgate in Stoke-on-Trent in April 1999, they are best known for their TimeSplitters series of games. After going into financial administration, it was announced on 3 February 2009 that the studio had been acquired by German video game developer Crytek and would be renamed Crytek UK. Crytek had a good relationship with the city of Nottingham due in part to its sponsorship of the Gamecity festival and its recruitment drives with Nottingham Trent University. In 2014, the studio would close and a majority of the staff transferred to the newly formed Dambuster Studios. In May 2021, the original founders reformed the studio, led by Doak and Ellis, to create a new entry in the TimeSplitters series. The reformed studio incarnation operated under Deep Silver. The second iteration was shutdown on December 11, 2023.
