For those of us having trouble with the jetpack method.

mostly correct, dont need super to jump up just start close to the edge that is next to the lamp immediately sprint and double jump with a weapon with +2 agility, then once above go to the lamp just on the other side of the rocks, reduce your weight and go to the next lamp while waiting for your weight to come done look over to the next lamp with your sniper and you will see the knight snipe him, then proceed to the next lamp, there will be one thrall that spawns from the hole but dont worry about him he wont do anything once at the last lamp, touch the pad ad jump on any rock and take out the ogre, then weight for the bridge to form then run across
