Find out the whereabouts of The Guru.
After the explanation, head for the cave. Scale the wall by climbing up the stick and swinging across a few hooks. Unfortunately, the Guru is not there. Murray will point you to his hut. Head over to the hut. The place is ransacked, and the Guru is still nowhere to be seen. Bentley informs you of a makeshift stockade that could be where the Guru is. Scale the cliff by jumping onto the trampoline to get to the high piece of land. Move forward to come across a hook. Swing and then spire jump onto two points, and then climb up using the two wall hooks. Head to the stockade, and the cutscene where the Guru shows up will trigger. After that, the job is complete.
