On the first play through I did in FC4 I remember I was able to climb the mountains up above the northern-most Shangri-La item (near the Anadekhi Ruins) and run the ridges to get behind Pagan's fortress. From there I slid down a slope to land in a small clearing and sniped everyone in the fortress for an easy clear.
I can't remember how I did this now, is this familiar to anyone?
