Grand Theft Auto: San Andreas/Firefighter

Prerequisites

 * Vehicle: Fire Truck. You can attract them by setting fires (for example, by shooting cars in their gas tanks or by throwing grenades at them), or go to a fire station to find one parked.  One such station is located just south of the Doherty garage in San Fierro.

Walkthrough
Get into your fire truck and drive to a suitable location. Press R3 to start the mission. Burning vehicles will appear on your map as blue targets.

Drive up to a burning vehicle and hit A or B to activate the water pump on top of the truck. Use the right thumbstick to direct the water.

After you extinguish the vehicle fire, burning passengers may get out. Douse them the same way. The only complication is that they run around a little bit.

Each level has the same number of fires (cars plus people) as the level number, but each car will have at most three burning passengers. After that another car will appear. In all you will put out 78 fires. You have to complete all 12 levels sequentially.
 * Level 1: One car
 * Level 2: One car with one passenger
 * Level 3: One car with two passengers
 * Level 4: One car with three passengers
 * Level 5: One car with three passengers and one empty car
 * Level 6: One car with three passengers and one car with one passenger
 * Level 7: One car with three passengers and one car with two passengers
 * Level 8: Two cars with three passengers
 * Level 9: Two cars with three passengers and one empty car
 * Level 10: Two cars with three passengers and one car with one passengers
 * Level 11: Two cars with three passengers and one car with two passengers
 * Level 12: Three cars with three passengers

There is a time limit for each level, which increases at each level.

Tips

 * Do not hit Y! This will end the mission and you will have to start over.  Any burning vehicles you were attempting to extinguish will explode.  This may result in the fire truck catching fire and exploding as well.
 * The fire truck is pretty durable. It won't suffer too much damage in collisions with other vehicles, and it can run over fences and other low obstacles. It is, however, very prone to rollover.  So watch your speed and cornering and be careful driving on nonlevel surfaces.
 * Aim the water hose above the heads of the victims, not at them (no water cannon style hitting). The fire should be put out in about one second if you sprinkle the water over them.
 * Get close to the flaming vehicle to extinguish the fire faster.
 * The flames you fight will not catch the fire truck on fire.
 * Angel Pine is a good place to do this mission as there is little traffic to get in your way.

Rewards
Finish level 12 to become fireproof. This means you can walk through fires without being harmed. But the concussive force of explosions can still hurt you.

Also, you receive cash bonuses:


 * $1850(?) after completing level 4(?)
 * $13450 after completing level 12
