An Elite with an energy sword comes through and straight at you. When you approach the door on the other side you will see two more stationary guns, kill the operators and see the door open. The Grunts may be sleeping and hard to see so be sure to kill all forces down here as you progress. Don't worry if the glass part of the walkway gets broken and you fall through - there is a secondary level to this bridge below. Move on across the bridge eliminating all enemies as you go. Move outside and eliminate all of the Grunts in the immediate vicinity before they can jump in the stationary guns. This puts you on one of the external elevated bridges we cross several times in the game. Exit the door on the other side and move through to the next door. Move through the room killing as you go being careful if you proceed directly through the center as there are two small bridges to get across or you fall to your death. Head on in to the room with more Covenant. No one around for a couple of seconds till small group of Covenant exit the door you need to go through. You start this level being dropped off by a Pelican inside one of the structures on the island we were just on.
