Rally Point: DELTA
The method i found most useful was to grab the Forerunner Pulse Grenades (orange spiked) when you reach the first platform. SAVE THEM. It's wise to clear some Covenant as you progress towards the Hunters to initiate Checkpoints. Then once you reach the Hunters, let one get right near the edge. Throw your Pulse Grenades at it's feet. He will back up to avoid it, and eliminate himself. *Anyone familiar with Aetheon from Destiny, will know this move.
