Mortal Shell II does not want you to be comfortable. Cold Symmetry’s standalone sequel, out August 20, 2026, for PlayStation 5, Windows and Xbox Series X|S, drops the stamina bar that governed nearly every fight in its predecessor and asks what is left when you cannot simply wait for the gauge to refill. The answer, across more than 60 dungeons and an interconnected dark fantasy world, is a game that forces decisions instead of rewarding patience. It scores 8.4 out of 10.

Eight Shells, No Stamina Gauge
The headline change is the removal of the traditional stamina system. Attacks, dodges and every other action now run without a gauge holding them back. That single decision reshapes the whole fight. Combat still carries melee and ranged weapons, posture-breaking mechanics, critical strikes and executions, but the pressure never lets up because you never have to stop.
Players possess the bodies of eight fallen warriors, called Shells, scattered across the world. Each Shell carries its own abilities and combat style, and each can be upgraded as you progress. Weapons can be customized and upgraded too, which lets you build toward a specific way of fighting rather than a single correct one.
- Eight playable Shells, each with unique abilities and combat styles
- Melee and ranged weapons, all customizable and upgradeable
- Posture-breaking mechanics, critical strikes and executions
- No stamina gauge restricting attacks or dodges
A Compact World With More Than 60 Dungeons
The map is not a sprawling empty plain. Cold Symmetry built a compact, interconnected open world, and it holds forests, temples, citadels and other locations. More than 60 dungeons sit inside it. Exploration pays out in additional Shells, weapons, upgrades and story elements, which means the reward for wandering is mechanical as well as narrative.
That structure matters more than it sounds. A tighter world with dense dungeons suits a combat system this aggressive. You are rarely more than a short walk from the next fight, and the next fight is rarely a pushover.
The Harbinger and the Stolen Eggs
You play the Harbinger, a being sent through a ravaged world to reclaim the stolen eggs of the Undermether. The eggs are guarded by dangerous creatures and powerful enemies. Along the way, the Harbinger can possess the bodies of eight lost warriors and recover their memories and individual stories.
The plot is thin on its face — a fetch quest with a body count — but the Shells carry it. Each fallen warrior you inhabit comes with a past, and the game treats those memories as the real reward. Possession is not just a mechanic here. It is the story.

What the Score Reflects
An 8.4 out of 10 puts Mortal Shell II in strong company. Metacritic’s aggregate sits at 84 out of 100, and the published critical score matches at 8.4/10. The source reports positive reviews from critics.
The praise is earned, but it is not unconditional. Dropping stamina is a genuine risk in a genre built on it, and Cold Symmetry has not replaced it with nothing — posture-breaking and executions carry the tactical weight that the gauge used to. The question is whether that trade holds up over dozens of hours. On the evidence of the design, it does.
What holds the game back from a higher mark is scope, not execution. The world is deliberately compact, and the plot is a search for stolen eggs guarded by creatures. That is a premise, not a story, and the eight Shells have to do the heavy lifting. They mostly do.
Why the Stamina Decision Matters
The most interesting thing about Mortal Shell II is not the open world or the dungeon count. It is the stamina decision. For a decade, action-RPGs have used the stamina bar as a pacing tool, a way to make every swing feel like a withdrawal from a finite account. Cold Symmetry removed the account.
That could have flattened combat into button-mashing. It did not. Posture-breaking and executions give the fight a rhythm that does not depend on a meter, and the eight Shells give it variety. The result is a game that trusts its players to manage themselves.
The compact open world is the right call for that system. More than 60 dungeons in a tighter map means density over distance, and density is what a stamina-free combat loop needs. A larger, emptier world would have exposed the design.
The weak point is the story. The Harbinger’s hunt for the Undermether’s eggs is serviceable, and the memories of the fallen warriors are the best material in the game, but the central plot never rises above its premise. That is a real cost, and it is why this is an 8.4 and not higher.
Still, the verdict is clear. Mortal Shell II is a confident, aggressive action-RPG that fixes its predecessor’s biggest constraint and builds a world worth exploring around it. Cold Symmetry took a risk with the stamina system and won. Play it on PlayStation 5, Windows or Xbox Series X|S.
