I wingsuit into the radio tower. Full directions are at the end if you want to climb it normally, then pick up a supply drop.
Then, it's off to North Krige Crest. Cliffs on two sides, but a path up to the back, and an interesting layout. This one was fun. A random attack from a creature (or passing blues) helped me. Don't miss the memory card. Lonely Shore way was amazing! Wingsuit kill! Winning! Then I picked up a wanted: dead mission, because it had snipers on an island.
Finally the regular route up the radio tower.
