Mortal Shell 2 Dungeon Locations & Puzzle Walkthroughs
Updated August 24, 2026 · Checked for the current launch build
Quick answer: Dungeon entrances are usually fog-covered side spaces tied to a nearby Beacon. Open the detailed routes below for the puzzle-heavy locations, then use the checklist and manually mark each dungeon complete on the in-game map. Published totals disagree because guides classify a few repeated or hidden spaces differently.

Four high-intent dungeon walkthroughs
Ravaged Tomb
Nochtean Gate elevator, pillar-and-plate solution, side-room materials, and the Duality Stone chest.
Crumbling Tunnel
Proxima landmark, Triarch Repeater map, every material, and the one-way collapse escape.
Deserted Mine
One Legged Wolf route, Common Moonshine, Laterite, and the 2,000-Coin chest under the lift.
How to avoid an incomplete dungeon
- Cross the fog boundary so the location name registers on the map.
- Check side passages before using an exit light, lift, or collapse-trigger pickup.
- Verify the dungeon's signature reward in your inventory.
- Open the map, hover the marker, and select Mark complete.
One-way warning: spend large carried Gloom and collect the side materials before taking the Triarch Repeater tablet in Crumbling Tunnel.
Dungeon checklist by region
This is the named set that can currently be tied to a useful route, item, boss, or Shell page on this site. It is not presented as a final universal count. Checks remain in this browser.
Second screen: game on the main display, this tab on a second monitor, a snapped window, or a phone. Tick as you collect. Ticks stay in this browser only — a phone and a PC do not share them.
Marrow Keep
Fainweald
Mammon
Play view hides the site header so the list can sit beside the game. Press Escape to leave it.
Compare the remaining map
For markers not yet expanded here, compare PowerPyx's numbered gallery with All Things How's Beacon-sorted list. When the counts differ, match names and nearest Beacons rather than list position.

Frequently asked questions
How many dungeons are in Mortal Shell 2?
Current launch guides publish different totals, including 35, 36, and 38, depending on how repeated names and hidden spaces are counted. Use the in-game map markers and a location checklist instead of treating one external total as authoritative.
Does Mortal Shell 2 mark dungeons complete automatically?
Not reliably. Hover the dungeon on the in-game map and use Mark complete after you verify its major reward and exit.
Which dungeon can become inaccessible?
The Shattered Beacon version of Crumbling Tunnel seals after you pick up the Triarch Repeater map and escape. Collect its materials before taking the tablet.
Evidence: Overall counts remain disputed: current location guides publish 35, 36, or 38 depending on classification. This page therefore labels its checklist as a sourced route set rather than a definitive total. Detailed pages use the walkthrough sources linked on each route. Reviewed August 24, 2026.
