No More Room in Hell 2 Raven Rock Walkthrough

Raven Rock is the headline Scenario map added with the Armageddon 1.0 launch on August 11, 2026. Set inside a darkened military bunker complex, it asks CRC Responders to push deeper underground, complete layered objectives, and extract the facility director under rising horde pressure. Expect longer clears than a casual surface POI loop—reviews routinely clock easy-difficulty first runs past an hour when the squad learns the layout live.

This walkthrough focuses on tempo, roles, and infection discipline rather than spoiling every keypad string. Codes and interactables can rotate with seeds and patches; your job is to keep stamina, medical tools, and communication intact until the extract craft arrives.

What makes Raven Rock different

Unlike open rural approaches such as Lewiston or dense street grids like Broadway, Raven Rock compresses sightlines. Corridors, blast doors, and stacked floors punish spray-and-pray firearms. Melee spacing, door control, and rear-guard assignments matter more than long rifle lanes. Sound cascades hard: one careless burst can pull runners through junctions you thought were cleared.

Treat every door as a checkpoint. Clear the room, call “clear,” then move. If your lobby skips callouts, Raven Rock becomes a friendly-fire museum.

Opening loop: gear before the deep push

Do not sprint for the deepest director objective cold. Open the compass (C), clear nearby optional rooms for melee, ammo you can sustain, Phalanx Pills, and supplies, then meet teammates. Hold E to link VoIP when you close distance. Share meds early—bunker finales punish silent infection.

Route template:

1. Spawn, ping allies, loot the nearest secure rooms.
2. Complete optional interactables that unlock stash dens.
3. Confirm which Critical-style progress nodes are active this deployment.
4. Stock gene therapy if you find it before the deep descent.
5. Only then commit to the director chain as a formed squad.

Pair this with Maps & Objectives and Getting Started if anyone is new to 1.0.

Mid-map discipline: junctions and noise

Raven Rock’s junctions are where runs die. Assign:

• Navigator — compass and objective callouts.
• Breacher — doors, tools, and first entry.
• Rear guard — runners and crawlers that spawn behind.
• Medic float — pills, gene therapy escort, revive priorities.

Guns stay quiet until a choke demands them. Prefer melee in halls; save shells for special infected or pad defense. If a teammate goes down mid-interaction, stabilize first—revive, suppress infection, reposition—then restart the panel. Panic re-pulls stack runners onto a body and end deployments.

Director objective and extract pressure

The director extract fantasy is a multi-step finale: secure the VIP objective, hold space while interactables complete, then move as a unit to extract. Keep infected players honest—Experimental Gene Therapy needs a two-step use (draw blood, wait for the bar, inject again). Read How to Treat Infection before you botch a cure in a dead-end hallway.

If the roster collapses to three living Responders, early green-hatch extract can save characters at the cost of character XP—see How to Extract. A Rescue Beacon in loadout can also change the math of a near-death mistake; details live on Rescue Beacon.

Difficulty and Solo practice

First Raven Rock attempts belong on Beginner or Normal with expendable Responders. Use Solo Mode to learn room flow without permadeath risk, then return online for rewards. Hard and Nightmare bunker clears assume map literacy and voice discipline.

Checklist before you ready up

1. Confirm difficulty and cross-play party.
2. Bring melee-forward loadouts and medical tools—see Loadouts & Credits.
3. Agree who holds gene therapy and who watches rear.
4. Rehearse extract callouts before the director step starts.
5. Leave if the lobby refuses communication.

Master Raven Rock’s corridor tempo and the rest of the 1.0 Scenario roster becomes easier to read. The bunker rewards patience, not hero sprints.
