This is a walkthrough for the Treasure Hunt, High Supply. Details on how to reach the air drop.
Reach the Air Drop
Head to the location shown above and you’ll find a corpse with a note beside him. After reading it, climb up the rock ahead then follow the path ahead until you come across an area with two grapple points. Take the first one up and then as you reach the second you’ll get the prompt to attach to the second one.
Follow the wooden planks along and enter the cave, then you’ll notice there’s two large gaps with a drop into some water. To get past here you’ll want to use the grapple points and swing across.
Melee the bush blocking the path and you’ll come across two more grapple points. After you’ve cleared the second point, use an explosive to destroy the fenced off area, then climb up three more rocks and collect the Air Drop to bring this mission to a close.
