Vigilante

Vigilante is a Vehicle Sub-Mission in GTA Vice City.

Take down criminals, playing the role of a police officer.

This is an optional endeavor, but it is required for 100% completion of the game. It's not time-sensitive, meaning it can be played at any point, even after the main storyline is completed.

This side activity is also present in Grand Theft Auto IV, GTA San Andreas and Grand Theft Auto III.

Vigilante - Mission Details:

The Vigilante side mission can be toggled on or off at any time while driving a Law Enforcement Vehicle.

The player has to chase down and kill criminals that are indicated in-game through the police dispatcher within a time limit. The criminals spawn in vehicles and will flee, but can also attack the player.

If the criminal's vehicle catches fire or is held in place, the occupant will bail out and run or attempt to acquire a new vehicle. As the player completes more levels, the targets will wield stronger weapons, will become more numerous and will appear in multiple vehicles.

The mission will fail if the player remains outside of a Law Enforcement vehicle for over 60 seconds, dies, the timer runs out, or the player is arrested. It is important to note that Vigilante does not grant immunity from the police, which will often pursue the player, making the mission a lot harder.
