Modifications

A modification is an alteration to a PC version of a game in the Grand Theft Auto series. These are usually post-consumer work and consists of using programs and/or large ZIP files. One the modification is installed, the program has to be altered in order to accompany the new info in the computer game. Careless use of modifications can either corrupt the game, the system, or even the entire computer.

WARNING
Do not use modifications until you have completed the game without them. Using modifications as crutches to the next level will spoil the fun of the original unmodified game.
