Grand Theft Auto United is a modification based on 'GTA San Andreas' for the PC. The target of this modification is to unite in only one game the game areas, the so called 'maps', of the two GTA Games 'GTA III' and 'GTA Vice City' on basis of the graphic- and physic engine of 'GTA San Andreas'. The map of 'GTA San Andreas' therefore gets replaced in the current version.
I just love to be able to roam around Liberty and Vice City with the SA Engine. Therefore I give it a 10/10 rating. Keep up the good work! :D
