There are a couple of ways to do this, all where the hunters are. Try each way too see what works for you.
Option 1: Where the hunters are, kill everything and have one player jump on the rock near the hill, Jump on his head and then throw a plasma grenade at aswell, jump up to the cliff and the grenade should help you make it.
Option 2: Drive a warthog to the same place and use its turrent to jump up to the cliff Option 3 Get an overshield and have a hunter whack you up, as you jump where the wall is low.
