Rockstar Lincoln Limited (formerly Spidersoft Limited and Tarantula Studios) is a British video game developer based in North Hykeham. It is the quality assurance and localisation studio of Rockstar Games. Steve Marsden and David Cooke founded the company as Spidersoft in May 1992. Initially, it primarily developed Game Boy and Game Gear ports of various titles, including pinball video games for publisher 21st Century Entertainment, which acquired Spidersoft in 1995. After 21st Century Entertainment shut down in March 1998, Take-Two Interactive acquired Spidersoft in June that year and renamed it Tarantula Studios. The studio continued working on Game Boy and Game Boy Color games, such as Grand Theft Auto (1999). In 2002, the development arm of Tarantula Studios was shut down and the quality assurance portion was integrated into Take-Two's Rockstar Games label as Rockstar Lincoln.
