Grand Theft Auto III is a 2001 sandbox-style action-adventure computer and video game developed by DMA Design (now Rockstar North), and published by Rockstar Games. It is the first 3D title in the Grand Theft Auto series. It was released in October 2001 for the PlayStation 2, May 2002 for Windows, in November 2003 for the Xbox and in November 2010 for Mac OS X. It was made available on Steam on January 4, 2008. The game is preceded by Grand Theft Auto 2 and succeeded by Grand Theft Auto: Vice City.
GTA III is set in modern Liberty City, a fictional metropolitan city based on New York City. The game follows a nameless criminal, who was betrayed by his girlfriend in a bank heist, and is required to work his way up the crime ladder of the city before confronting her. GTA III is composed of elements from driving games and third-person shooters.
The game's concept and gameplay, coupled with the use of a 3D game engine for the first time in the series, contributed to Grand Theft Auto III's positive reception upon its release; it became 2001's top selling video game and is cited as a landmark in video games for its far-reaching influence within the industry. GTA III's success was a significant factor in the series' subsequent popularity; as of 2008, five GTA prequels set before events in GTA III have been released, particularly Grand Theft Auto: Liberty City Stories which revisits GTA III's setting a few years prior. GTA III's violent and sexual content has also been the source of public concern and controversy.
