On this page of our trophy guide to RAGE 2 we have provided a detailed description of the Goon Fire bronze trophy. The achievement is awarded for blowing up a Goon in the air with the Booma Tank. From our description you will learn where you can find suitable tank and how to steal it.
Booma Tank can be found in various places on the world map. Example spot with the tank can be Yeoman Growery bandit's den. This area is located in the northern part of the Broken Tract region, a short drive north of Gunbarrel.
The bandit den has enemies at level 6. It is not necessary to fight them, because the tank is parked in front of the camp.
You can immediately take advantage of an on-board cannon to kill some bandits or drive it to Gunbarrel to add it permanently to your garage.
