 * 3) Procure at least two Forklifts, and proceede on to the next area. Clear out all enemies.
 * 4) Launch the forklifts over the gate using Armor Lock.
 * 5) Jump onto the adjacent roof. One player should stand on the rock, with the other jumping off the first's head.
 * 6) Once on top, go behind the gate. Have the others respawn with you.
 * 7) Enter the forklifts and drive up the hill as far as possible. Use the other forklits to push the first up further.
 * 8) When you cannot move further, dismount. You are now out of the map.

From the level start #2

 * 1) Acquire Armor Lock.
 * 2) Position one of the forklifts near the round building of the first settlement.
 * 3) Get the Phantom to come.
 * 4) Use the forklift and a grenade to launch yourself onto the Phantom.

 * 6) Jump off of the phantom as it flies past the hill. You are now out of the map.
 * 7) Walk along the wall separating the first to settlements to access the larger area of the level.

From the Pylon
This method requires two players.
 * 1) Acquire Armor Lock.
 * 2) Use the Nightfall forklift glitch to go through the gate.
 * 3) Jump off the cliff onto the hovering Phantom.
 * 4) Have the other player kill the other enemies and open the gate.
