I gave in and used the Vercetti Estate glitch to finish Firefighter 🥲
I'm playing the 10th Anniversary edition on Android. I tried to do Firefighter fair and square. During multiple attempts, I figured out that the hose actually followed along when I swiped the screen to look around, so that made things easier. The highest level I got using the normal method was level 10. I was in Vice Point, near the Links View Apartment. I put out the fires in the 3 piled up vehicles first and managed to put out a couple people who came out. Some managed to run further away, so I followed the ones who went the furthest to put their fires out, leaving a couple running around near the apartment. I went back for them with over 2 minutes left on the timer. I was focusing on dousing one of the guys when, all of a sudden, the mission ended and I heard an explosion, the game saying "You're too late." I had no idea what happened. So I restarted the mission but, once again, I got a moving vehicle target in level 4. I got stuck chasing the car going in circles around the Jeweler's, an area with tight corners. When I noticed that my time was running out, I just called it quits and settled for the Vercetti Estate door glitch. 😑 Move the fire truck up the stairs, trigger the mission and drive into the doorway, spawn inside facing the door and with the fire automatically extinguished, drive out, turn around rinse and repeat. Yes, it was much easier, but I'm not entirely proud of it, since I beat Paramedic and Vigilante fair and square (although I did use a Tank for the latter). After the mission I drove the fire truck to the edge of the Estate close to the sea... and I blasted it repeatedly with the Rocket Launcher. Even when it fell into the water, I blasted it a few more times.
