Bravo heads underground to find a way back to the surface. The squad is split in two for a while, the station hides something important, and the chapter ends in a sewer with a Corpser. Lots to collect: 6 collectibles, 8 Hard Cases and 2 supply caches.

Find a way to the surface
- The opening objective is Find a way to the surface. The tunnels lead to a downed Raven whose radio is still transmitting; you try to reach Control, and then the wreck drops further with Dom and Lucas still inside. For a while you play as two separate pairs.
- Keep an eye out on the way for the Damaged Gnasher Shotgun on top of a crate (collectible 1) with Hard Case 1 next to it, and for the Parchment and Powder Pouch in the ammo piles (collectible 2).
Explore the station
- Back together, the squad is told to explore the station and investigate the Locust device inside — it turns out to be listening in on COG radio. You then have to survive the ambush that follows.
- The subway lobby has Hard Cases 2 and 3 and a supply cache, and Beth Avila’s tags are in the pile of bodies in the station (collectible 4).
Exit the subway tunnels
- Exit the subway tunnels: follow the platform, then clear it. The tunnels are full of pickups — the Parchment With Indecipherable Writing in the wrecked section (collectible 3), the Maintenance Worker’s Bloodied Flashlight on the left in the dark stretch (collectible 5), Hard Case 4 in a collapsed tunnel and Hard Case 5 by the derailed train.
Climb to street level
- Through the station exit, climb to street level over the rubble and look at what’s left of the block. Locust arrive soon after. Up here, Hard Case 6 is near the toppled statue and Hard Case 7 at the edge of the subway cave-in.
- The next objective, Get back topside, sends you down again: kill the enemies, enter the tunnels (a short scene shows the Locust on the move), and continue into the sewer. Just inside, a body wears Erick Davis’s tags (collectible 6), with Hard Case 8 and a supply cache beside it. Stock up here.
Boss: Corpser
- Further into the sewer a Corpser — an armoured, many-legged giant — attacks.
- How to beat it:
- Bullets alone won’t do much. The damage comes from the stone pillars: stand near one, let the Corpser charge or slam at you, and move aside so it hits the pillar, which then falls on it.
- In the first room, bait it into one pillar and move on; the real fight is in the next chamber.
- Jump over the shockwave of its ground slam, and shoot it whenever it surfaces to keep it coming at you.
- Bring down every pillar to finish it — and the chapter.
