Vigilante turns any police vehicle into a crime-fighting tool. Huang reads the latest reports on the police computer, drives to the scene and shoots the criminals before they get away. For 100% you only need a bronze medal, but a gold medal adds a lasting armor bonus, so it is worth finishing the job properly.

Starting a job

Only a few vehicles carry the police computer: the Police Patrol, the NOOSE Enforcer and the FIB Rancher. Climb into one and hold the button shown in the hint to open it. The screen lists three recent crimes, and you pick one to be dispatched to. Each entry shows the distance, how many felons are involved, how heavily armed they are and what they drive, so you can choose an easy target while you are learning.

The crime types include murder, mugging, assault, arson, grand larceny, street racing, rioting and hit and run. Once you accept, the game gives you the location and a timer. Reach the scene before the timer runs out. Once you arrive the timer switches off, and you do not have to stay in the police vehicle after the job begins.

Waves and kills

Each job is one wave of criminals. The job ends as soon as you kill the last one, and you restart by getting back into a police vehicle and opening the computer again. You need five waves in total, and they do not have to come back to back, as long as you never fail along the way. Failing means being wasted or busted.

Keep moving at the scene. Criminals can be on foot or in vehicles, so close the distance with the police vehicle and then switch to a gun for the kills.

Medal rates

Your medal depends on the share of criminals you kill across the five waves.

Medal	Criminals killed
Bronze	At least 60%
Silver	At least 80%
Gold	100%

A bronze medal is enough for 100%. If you want gold, pick crimes with few felons and light weapons for your first waves, and take on the heavily armed groups once you are confident.

Bullet Shield

Finish all five waves with a 100% kill rate and the game announces that you have unlocked Bullet Shield. From then on body armor is worth double. It is a handy bonus for the later story missions and for the other side jobs, so come back for the gold medal even if you scraped through with bronze.
