Introduction

The Dungeons hub is your atlas for the shattered world of Mortal Shell II, home to more than 80 dungeons scattered between the world’s lost landmarks. From derelict temples of ancient deities to forbidden forests patrolled by desperate and fanatical foes, each dungeon is a self-contained challenge with its own enemies, layout, secrets and rewards. This hub organizes them by region — derelict temples, forbidden forests, icy graves and citadels carved from bone — and provides walkthroughs, loot tables and route recommendations so you know exactly what to expect before you step inside. Dungeons are where you find the game’s best Shells, weapons, upgrades and curiosities, and many hide optional bosses and story lore that the main path skips. Whether you are a completionist hunting every treasure or a casual player following the critical route, the region guides and best-order recommendations here will keep you from getting lost.

Core Mechanics

Dungeons in Mortal Shell II are compact, handcrafted challenge spaces rather than procedurally generated grinds. Each one is built around a theme — a derelict temple, a forbidden forest, an icy grave or a citadel carved from bone — and populated with enemies that fit that theme and reward the right tactics. Completing a dungeon typically means fighting through its rooms, solving the occasional environmental puzzle, defeating a boss or elite guardian, and claiming the reward at the heart: a Shell, a weapon, an upgrade or a curiosity with lore value. Because the world is compact and interconnected, dungeons are also how you access the best gear and the optional bosses, and many contain hidden rooms and secrets that reward thorough exploration. The regions scale in difficulty, so the recommended dungeon order — roughly temples and forests first, then icy graves, then citadels of bone — keeps progression fair.

Advantages

The 80+ dungeon count gives Mortal Shell II an enormous amount of content to explore, and because the world is compact and interconnected, the density means there is always something rewarding just off the beaten path. Dungeons are the primary source of the game’s best gear — Shells, weapons, upgrades and curiosities — which makes exploration genuinely rewarding rather than busywork. The region system gives each dungeon a distinct identity: a derelict temple feels different from an icy grave, with different enemies, layouts and loot. Optional bosses and hidden rooms add completionist depth, and the lore you find inside fills out the story of the Harbinger, the Undermether and the false gods. For players who love that soulslike blend of exploration and combat, the dungeon content is the meat of the game.

Challenges

The main challenge of dungeons is their density and interconnected layout. With more than 80 of them scattered across a compact open world, it is easy to miss entire regions, hidden rooms or optional bosses without a guide, and the walkthroughs here exist precisely because getting lost is common. Some dungeons gate progress behind environmental puzzles or require items found elsewhere, which can send you backtracking. Difficulty also scales sharply into the later regions — icy graves and citadels of bone assume you have upgraded your weapons and learned the posture system, so rushing them early will end in frustration. Finally, because much of the dungeon data comes from the open beta and official materials, exact enemy placements and reward tables may shift slightly at the August 20, 2026 launch.

Frequently Asked Questions

How many dungeons are in Mortal Shell II?+
Mortal Shell II features more than 80 dungeons scattered across a compact, interconnected open world. They range from derelict temples and forbidden forests to icy graves and citadels carved from bone, and they are the primary source of the game’s best Shells, weapons, upgrades and curiosities. Not all dungeons are required for the main campaign — many are optional and hide powerful gear and lore.
What is the best dungeon order?+
A good general order is to start with derelict temples and forbidden forests, which are moderate and teach the basics, then move to icy graves for tougher challenges, and finally citadels of bone — the hardest region with the strongest gear. Within each region, follow the critical route first and clear optional dungeons as your gear and confidence improve, so the difficulty curve stays fair.
Do dungeons have hidden secrets?+
Yes. Many dungeons contain hidden rooms, environmental puzzles and optional bosses that reward thorough exploration, and hidden dungeons exist too — accessed through the interconnected world rather than obvious entrances. Our walkthroughs mark these secrets so completionists can find every Shell, weapon and curiosity without aimless backtracking, and so casual players can decide how much optional content they want to chase.

Quick Tips

💡

Do not clear every dungeon on the critical path immediately. The world is compact and interconnected, and the game expects you to return to earlier regions with better gear. Clearing temples and forests first, then revisiting with upgraded weapons, makes the later icy graves and citadels far more manageable. Clear a dungeon with the walkthrough open on a second screen, since the interconnected layouts hide entire rooms behind subtle branches.

💡

Carry a ranged sidearm into every dungeon. Sidearms let you pull enemies one at a time out of packs, test around corners and punish runners — which prevents the dreaded gang-up deaths that end most dungeon runs. Check the reward table before committing to a detour, so you never burn an evening chasing loot your build cannot even use.

💡

Check the loot table before a long detour. Optional dungeons cost time and resources. Our reward tables tell you whether the Shell, weapon or curiosity at the end is worth the trip for your build, so you can skip grind and chase what you actually need. Return to cleared dungeons after upgrading — hidden rooms and optional bosses are far more approachable with better gear.
