Rockstar Leeds (formerly Mobius Entertainment) is a British video game developer. Based in the city of Leeds, West Yorkshire, Rockstar Leeds has primarily published handheld games for Game Boy Color (GBC) and Game Boy Advance (GBA), as well as developing Midnight Club 3: DUB Edition and the Grand Theft Auto Stories games for the PlayStation Portable (PSP).
Founded in 1997 by Gordon Hall, Jason McGann, Dave Box, Ian Bowden and Justin Johnson. The company consists of 75 game designers and game programmers.
In April 2004, the company was acquired by Rockstar Games and renamed Rockstar Leeds. The offices of Rockstar Leeds were once located in a converted 18th-century church in the Pudsey area of Leeds. After the release of Grand Theft Auto: Liberty City Stories in late 2005, the studio relocated to the City West office park.
