'Firefighter'
Get in a firetruck and press UP to toggle the 'Firefighter' odd job. You can find a firetruck at the fire station in Downtown (see picture). If you get there and can't see a firetruck, drive to the back of the building and then back again - one should have spawned.
There are 15 levels to complete and a checkpoint will come in at every 5. The firefighter mission is available at any point in the game.
You have to drive to locations on the map where there is a fire, (represented by the blue blip(s) on the radar map). You will have a time limit to get to where the fire is and put it out. Firetrucks are very durable vehicles, and can therefore come out of a lot of collisions without too much damage being done. They are also quite difficult to tip over. Drive at very high speeds to the fire location, thus giving you more time to extinguish the fire. You can turn the siren on and off by pressing DOWN, for traffic to move to one side and let you through. The fire will always consist of a parked vehicle and, later a set amount of people inside, who will flee out on fire as soon as you have hosed out the fire on their vehicle. You have to put out the fire on these people too, in order to get to the next level. The higher the level, the more fires you have to put out, i.e. more vehicles, with more people inside them.

To use the water canon press circle and use the left analog stick to change the direction of the water; up, down right and left. Keep the hose fixed on one vehicle at a time and when the people inside get out hose them down into walls - your aim doesn't have to be totally accurate. Every person you extinguish is worth an extra 15 seconds on the timer. If a person dies, because you have left them on fire for too long, you will lose 15 seconds. A message will display at the bottom of the screen telling you where the location of the fire is. Your time limit will be generated on how far away the fire is from you.
REWARD: Victor will be completely fireproof.
