Firefighter is an emergency vehicle-based side mission available in Grand Theft Auto III.
Description[]
In order to start the mission, the player must find a Firetruck and press the button shown on the instruction text (platform dependent) to toggle the side mission on or off.
Once the mission is started, the player is given the location of a burning vehicle in a random neighborhood of the current island, and a time limit on screen below the HUD.
The player must drive the Firetruck to the burning vehicle's location and extinguish the fire using the Firetruck hose by using the attack button.
After putting out the fire within the time limit, the level is completed and the player will get a timer bonus for the following level.
In order to achieve the 100% Completion requirement, the player must extinguish 20 fires on each island (60 fires in total). Completing 20 levels in a row is not necessary. The player can toggle off the side mission and continue another time, tracking their progress through the Stats menu.
Rewards[]
For every 20 levels completed on each island, a Flamethrower pickup will be delivered to the player's safehouse of the respective island.

Replay Exploit[]
In the original PC versions, an exploit can be used with the Replay feature. Due to a flaw in the code for the transition to Replay mode, any fire will be automatically extinguished when pressing the Replay button, including the ones created by the Firefighter side-mission. As a result, the player can complete the side-mission by repeatedly going to Replay mode after a fire is placed on the map.
This exploit is not available in the PC version of The Definitive Edition, as this version is built on top of the Mobile version, which lacks the Replay feature.
