WHERE IT STARTS:
The Treasure Hunt starts at FELICIDAD, PROMISE PEAKS, SIERRA PERDIDA.
Just north of PATRIOTAS PEAK.
THE NOTE SAYS:
"We've done our times in the mud and the jungle. We've watched loved ones die. We've survived the revolution of '67, but we won't survive Anton.
Guerrilla, if you're reading this, we want to help you. We left you a cache of supplies, and a legacy. There are three switches between you and our gift. To get to it, all you need to do is follow the powerlines and flip them.
Survivors of '67"
WHAT TO DO:
You have to activate 4 switches in total.
3 in 3 houses and 1 right opposite of the locked house.
One switch is in the small hut at the top of the settlement. Smash the door to get inside.
The second one is in the turquoise colored house.
It has an open window. Climb onto the roof from the other side and let yourself drop in front of the open window to climb in.
The third switch is in the yellow house.
The access point is down below. Smash the wooden barricade at the base of the house next to the two black tanks.
Then you can climb inside.
Now you can pull the switch at the base of the settlement to open the locked door.
