Unfortunately, in GTA 5 story mode, you cannot be a firefighter in the traditional sense. The game does not have any specific firefighter side missions for players to engage in. However, there is one instance during the story missions where you do get to partake in a firefighting scenario.
In the story mission called “The Bureau Raid,” you play as Michael, one of the game’s protagonists. In this mission, you and your crew infiltrate the FIB building to retrieve some important files. During the heist, you come across a fire on one of the floors, and you are required to extinguish it using a fire extinguisher.
While this is a brief moment and not a dedicated firefighting mission, it does provide a small taste of what it would be like to be a firefighter in the game. You get to experience the urgency and intensity of dealing with a fire situation, albeit in a limited capacity.
It’s worth noting that GTA 5 is primarily an action-adventure game focused on criminal activities and open-world exploration. The game offers various activities and missions related to being a criminal, such as heists, robberies, and car chases. However, firefighting is not one of the prominent features or gameplay mechanics in the game.
If you are looking for a more in-depth firefighting experience, there are other games specifically designed to simulate the life of a firefighter. These games often offer realistic firefighting scenarios, equipment, and missions that allow players to experience the challenges and responsibilities of being a firefighter.
While GTA 5 may not provide a dedicated firefighter role, it offers a vast open world with numerous other activities and missions to engage in. From racing cars to flying planes, there are plenty of exciting and action-packed adventures to be had in the game.
While there is a brief firefighting moment during one of the story missions in GTA 5, there are no dedicated firefighter side missions or roles in the game. However, there are other games available that focus specifically on the firefighting profession if that is what you are looking for.
