This page of the Far Cry 6 guide contains a walkthrough of the Yaran story titled Heavy Metal, a side quest in Madrugada. This walkthrough explains how to start the quest and how to destroy Jose Castillo's advertising billboards.
Rewards for completing the quest
- Tank 1944 Petrov HS-100 "Senor Pinga" is a uniquely painted tank, which will be added to the vehicles list at the pickup points.
- Vehicle Scraps x100.
Destroy the Jose Castillo billboards
You can start this quest right after completing the Yaran story Stealing Thunder. You must meet again with Zenia Zayas, who's standing by the garage where you parked the stolen tank in the previous mission.
Get in the tank and start driving on paved roads near the town of Verdera in Madrugada. Every time you see a big billboard (as in the picture), use your tank's cannon to destroy it.
Two additional comments:
- Your actions will probably cause the soldiers you encounter to attack you. You can eliminate them or ignore them, as the tank has very durable armor.
- However, the mission does not require the billboards to be destroyed by a tank. If, for some reason, you lose the tank (e.g. you make the tank fall off a cliff), you can destroy the billboards with the help of other vehicles (drive straight into the billboards), weapons (rocket launcher) or gadgets (grenades).
Destroying the required number of billboards will complete this short side mission.
