Vigilante

Overview

Vigilante is a GTA IV side mission run from the Police Computer of a Liberty City Police Department or other law enforcement vehicle. It becomes available after Crime and Punishment and is exclusive to the original game, so it cannot be played in the Episodes from Liberty City. Entering an FIB Buffalo, NOOSE Cruiser, NOOSE Patriot, Police Cruiser, Police Patrol or Police Stockade and opening "View Current Crimes" lets Niko Bellic choose a crime to respond to. Each is one of three types: gang activity (kill a group of thugs), stolen vehicle (chase down criminals in a car) or criminal on foot (kill a single fleeing suspect). The scene must be reached within a time limit, and criminals carry heavier weapons at higher levels.

Walkthrough

1. Complete Crime and Punishment and get into an eligible police vehicle.
2. Open the Police Computer, choose "View Current Crimes" and pick a crime in your current borough.
3. Drive to the marked location before the timer runs out; leaving the car gives you 25 seconds to get back into a police vehicle.
4. The timer stops on arrival; kill the suspect or suspects.
5. Repeat until 20 levels are complete.

Tips

• Crimes cannot be started near borough borders, where the computer shows a connection error.
• Time limits use straight-line distance, so jobs across water or in Bohan can be nearly impossible; skip them.
• Wanted levels still apply during a level but are cleared when it ends.
• From around levels 17 to 19, targets use rifles, shotguns, sniper rifles and grenades, so arm up beforehand.
• An Enforcer, Annihilator or Police Maverick can continue a level that was started in another vehicle.

Rewards and unlocks

• "Cleaned the Mean Streets" achievement for completing 20 levels.
• 20 levels of any type, in any borough and not necessarily in a row, are required for 100% completion.
