Grand Theft Auto 2
Grand Theft Auto 2 is an action-adventure video game developed by DMA Design and published by Rockstar Games. It was released on 22 October 1999 for Microsoft Windows and the PlayStation, followed by Dreamcast and Game Boy Color releases in 2000. It is the sequel to 1997's "Grand Theft Auto", part of the "Grand Theft Auto" series. The open world design lets players freely roam Anywhere City, the setting of the game.
Multi Theft Auto
The first version of "Multi Theft Auto", dubbed "Grand Theft Auto III: Alternative Multiplayer", attempted to fill in this gap by extending an already existing cheating tool with functionality that allowed the game to be played with a very crude form of two-player racing over a computer network purely as a proof of concept, similar to how the now-defunct XBAND service worked by manipulating game memory in order to add online multiplayer functionality. Newer versions of "Multi Theft Auto" with increasingly better gameplay and other improvements were released based on the same concept of game manipulation, by a small team of developers.
