[DLC00]

Defend the Evacuation Zone: After a cutscene, you'll be introduced to new characters Alicia Valera, Mihn Young Kim, Tai Kaliso, and Michael Barrick. You'll be swarmed by Drones, Boomers, and Reavers. A hidden area behind you has unlimited ammo, and a ramp to the right leads to a turret. A Longshot and Mortar are also available.

Once the turret is destroyed, two Emergence Holes (e-holes) will appear. Use grenades to seal them quickly. After about 2 minutes, a HOD command center will become available to use for targeting remaining Locust.

Find Echo Squad: After defending the zone, break down the gates and proceed through the city. You'll pass a Brumak and a group of Wretches. Follow the hallway on the right.

Another e-hole will open at the end of the hallway. Deal with it and move into a large area filled with Locust. Echo Squad is in the central circular area.

Engage the Locust from the central area. Use the sniper rifle on the two snipers located on top of buildings. After the wave, more e-holes will appear.

The middle area offers cover, but the steps to the building provide better vantage points. The sandbags and crates on the right offer ammo and a Mortar, and serve as a good sniping spot.

Find the Vault: Enter the burning bank. A metal gate blocks the Vault. To the left, an open door with a blue panel leads to rooms with ammo and a switch to open the gate.

Proceed down the hallway and be ambushed by Wretches and Grenadiers. Past them, you'll reach the outside of the Vault. Ammo is available in cages.

In the next area, you'll face another ambush with e-holes and Flame Grenadiers. After defeating them, open the door to the Vault to end the chapter.
