Grand Theft Auto: Liberty City Stories is a 2005 action-adventure game developed in a collaboration between Rockstar Leeds and Rockstar North, and published by Rockstar Games. The ninth installment in the Grand Theft Auto series, it was initially released as a PlayStation Portable exclusive in October 2005. A port for the PlayStation 2 was later released in June 2006. At the time of release, the recommended retail price of the PS2 port was around half the price of the PSP version, because the PS2 version does not feature the custom soundtrack ripping capability of the PSP version. Ports for iOS, Android and Fire OS devices were also released in December 2015, February 2016, and March 2016, respectively.

Rockstar Leeds Limited is a British video game developer and a studio of Rockstar Games based in Leeds. Ian J. Bowden, Dave Box, Gordon Hall, and Jason McGann founded the company as Möbius Entertainment in December 1997 after working together at the studio Hookstone. Möbius worked with SCi on two games: Alfred's Adventure, a remake of the Twilight-developed Alfred Chicken, and the cancelled Titanium Angels. From 2001 on, the studio created Game Boy Advance games for several publishers, including multiple for The 3DO Company and Max Payne for Rockstar Games.
