Grand Theft Auto III is set in a dark and gritty world of crime. With people from all walks of life in the scruffy and dark city of Liberty, the brutal darkness of underworld life is within reach! With a shocking soundtrack and a very open-ended world, you'll have a lot of freedom and fun as you follow the game's voice prompts to uncover a darkly humorous storyline!
In the game, you take on the role of a criminal in the city, and you rise to prominence by completing a series of organised crime missions, usually gunfights, bank robberies, assassinations, etc. Other missions outside of crime include driving taxis, putting out fires, racing, flying, etc. Grand Theft Auto is also known for giving players the freedom to do as they please within the game. Unlike traditional action games where there is only a one-way calendar, in Grand Theft Auto you can choose which missions to play first.

The game creates a big city with a diverse ethnic and cultural mix. Players will take on the role of a man who lives in an open-ended city where crime is allowed and the game caters for those who like to play as a male hunk. The game also allows for the indiscriminate use of various weapons on Big Sister. Nonetheless, wrapped up in the excitement of violence and pornography, the revamped Grand Theft Auto 3 does have an irresistible appeal. Grand Theft Auto 3 completed the transition from 2D to 3D, and for the first time, PC gamers felt the difference between console games and computer games

Weapons and vehicles can be used at any time; explore the Liberty City map where you can discover even more additional gameplay; experience the Drama mode and engage in intense firefights with the Mafia in the city.

 Egg system
