Mad Island Gang
The Mad Island Gang is a small gang that makes an appearance in Grand Theft Auto 2. Their only turf is in Mad Island. Everytime the player is spotted by the gang they automatically attack, regardless of how much respect the player has. They also play no part in the game.
Mad Island is not available on the PlayStation version of GTA2, and, as a result, the Mad Island Gang isn't in the PlayStation version, either.
