This mission is activated by pressing the correct button when or after being prompted when entering an Firetruck. You can get a Firetruck from Escobar Intl. Airport or at the F.D.V.C. station in southern Downtown, or when you toss a few Molotov Cocktails or go crazy with a Flamethrower.
The Firefighter Mission has a simple premise - put out the vehicles and the civilians on fire in the time limit. Complete twelve levels to fulfil the requirements of this mission.
The twelve levels carry monetary rewards for completing them, listed below:
| Level No. | Reward |
| Level 1 | $50 |
| Level 2 | $200 |
| Level 3 | $450 |
| Level 4 | $800 |
| Level 5 | $1,250 |
| Level 6 | $1,800 |
| Level 7 | $2,450 |
| Level 8 | $3,200 |
| Level 9 | $4,050 |
| Level 10 | $5,000 |
| Level 11 | $6,050 |
| Level 12 | $7,200 |
The amount of money that you can make from this mission is $32,500, a good amount of money to have on hand, especially when you are either just getting into the game, or when you're buying Assets, Properties and weapons.
With that in mind, here comes...
The Strategy
There is some challenge to this side-mission, as per usual.
You have twelve levels to complete. You have to extinguish a car fire at Level 1. At Level 2, things will get interesting, as you also have to put out a car fire AND the driver, who has also been caught alight. You have to do this in a time limit. At Level 4, this will max out at one vehicle and three civilians, before an additional car fire is added and the process is effectively repeated again. At Level 12, you have to deal with three car fires and nine civilians. If you run out of time, the mission ends.
Issues
The standalone issue is time. You are given time based on how fast you completed the level before, and it will carry over throughout the mission, meaning you can accumulate quite a bit of time. However, in the earlier levels, you will have to be cautious not to waste time.
Another issue is the water cannon. You will need to get accustomed to it before attempting this mission. Aiming it can be an issue, but get used to its controls and sensitivity, and you should be able to extinguish the fires in a good enough time.
There are smaller issues, such as damaging the Firetruck or the civilians running into tight spaces, but these are relatively minor in comparison to the others. The Firefighter Mission is more like a breath of fresh air if you do them after enduring the difficulty of the Paramedic and Vigilante Missions, and having to waste several hours doing those missions and the Taxi Mission.
Advice
With this being one of the easiest of the so-called "R3 Missions" group, you don't have too many problems to deal with. Just try to bear the issues in mind, and tackling them correctly is enough to guarantee success.
Reward
The ultimate reward for this mission is the Fireproof Feature. Put simply, you are fireproof. This is a valuable perk to have when you are doing some of the Rampages, and in the occurance of a very rare fire attack from your enemies, or when when everything gets "heated", if you would pardon the pun. Have a good time testing it out.
