Hopefully someone can help with this. I tried to take a tower (well, get to it) you have to grapple up to it. Now I've done the first few grapples then there's 3 in quick succession moving from one side of a rock wall to another. But I can't figure out where I go from there? It looks like you swing between the cliffs and around the corner to the left possibly and jump onto a ledge but I kept falling off. Or you can get to a proper ledge on the right hand side but then can't reach anything. There's snipers above you and a zipline higher up but I couldn't figure it out, I just got pissed off and headed east instead. Anyone recognise it? There's a load of yaks and bharals knocking about the place.
