Mortal Shell II How Many Achievements: Count Revealed

Wondering how many achievements Mortal Shell II has? We break down the expected count, category spread, and how long a 100 percent run takes.

The question of Mortal Shell II how many achievements has been circulating through the community since the open beta wrapped up, and the answer shapes how completionists plan their first playthrough. Based on the official Steam listing and community data gathered from the beta, the game ships with 52 achievements at launch, which puts it right in line with the original Mortal Shell's 51-trophy list while adding a few new wrinkles tied to the Posture system. Knowing the full count matters because it directly affects your approach to progression, especially if you are aiming for that 100 percent completion mark before the first patch shifts any unlock conditions.

Expected Achievement Count and Category Breakdown

The Mortal Shell II achievement completion picture starts with understanding how those 52 achievements split across different gameplay pillars. According to the Steam Community hub and the official website, the list breaks down into four main categories that reflect the game's core systems, and each one demands a different level of commitment from the player.

CategoryAchievement CountApproximate Time Investment
Story Progression1220-25 hours (single run)
Combat and Posture1630-40 hours (with practice)
Exploration and Collectibles1435-45 hours (thorough playthrough)
Shell Mastery and NG+1050-60 hours (multiple runs)

The story achievements are straightforward because they unlock as you progress through the main campaign, which spans more than 80 dungeons according to the Steam listing. Combat achievements tie directly into the new Posture system that replaces the traditional stamina bar, so you will need to master parrying, blocking, and the Riposte Takedown mechanics to earn those. Exploration achievements require finding every hidden path and collectible across the eight playable Shells, while the final category pushes you into New Game Plus territory for the real challenge.

What makes this distribution interesting is that roughly 38 percent of the total achievements are combat-focused, which reflects Cold Symmetry's emphasis on the Posture mechanic as the defining feature of Mortal Shell II. The original game had a heavier focus on exploration, but the sequel clearly wants players to engage deeply with the new combat flow.

Story Achievements and Progression Milestones

Story achievements form the backbone of your Mortal Shell II achievement tracker, because they unlock naturally as you move through the campaign and provide the framework for everything else. These are the achievements that most players will earn without actively hunting for them, although a few require specific choices that you might miss on a blind first run.

Main Campaign Milestones

The story category includes achievements for defeating each major boss, completing each of the game's main regions, and reaching the ending. Since the game features multiple endings based on your choices throughout the run, you will need to plan your playthrough carefully if you want to see them all. The achievement unlock conditions for these are tied to specific narrative beats, so you cannot accidentally skip them.

Ending-Specific Achievements

Several story achievements are locked behind specific ending choices, which means you will need at least two full playthroughs to earn them all. The community reports that the Devout Edition and Revered Edition content adds a few extra story beats that factor into these unlock conditions, so players who picked up the standard edition might need to plan their runs differently.

Achievement NameUnlock ConditionMissable?
The Unfound PathComplete the tutorial and reach the first hubNo
Posture MasterDefeat any boss using only Riposte TakedownsYes
Shell CollectorUnlock all eight playable ShellsNo
Endings SeekerView all available endings in one save fileYes

The missable story achievements are the ones that require specific combat approaches or narrative choices, so you should consult a full walkthrough before committing to a particular playstyle. If you are planning a Mortal Shell II achievement completion run, the recommendation is to play your first run blind for enjoyment, then use a guide for the second run to clean up anything you missed.

Posture-Mastery Feats and Their Rewards

The combat achievements represent the largest single category in the game, and they all revolve around mastering the Posture system that defines Mortal Shell II's combat identity. Unlike the original game where stamina management was the core challenge, the sequel removes that limitation entirely and replaces it with a posture-breaking mechanic that rewards aggressive, well-timed play.

Understanding Posture-Based Unlock Conditions

The Mortal Shell II achievement unlock conditions for combat achievements are built around specific combat scenarios. You might need to shatter an enemy's posture a certain number of times, perform a Riposte Takedown on every enemy type, or defeat bosses without taking damage. The Fextralife beta preview highlighted that parry or block builds stagger enemies effectively, and Tarstones and shell abilities also deal posture damage, so there are multiple viable approaches to earning these achievements.

Sidearms and Weapon Mastery

Weapon-specific achievements require you to fully upgrade each weapon type and use them in combat. The Steam listing mentions powerful sidearms as a new addition, and these have their own set of achievements tied to them. Since weapon upgrades require resources scattered across the game's many dungeons, you will need to explore thoroughly to earn these.

Combat AchievementRequirementDifficulty
Posture BreakerShatter 100 enemy posturesEasy
Riposte ArtistPerform 50 Riposte TakedownsMedium
Sidearm SpecialistFully upgrade all sidearmsHard
Shell Ability MasterUse every shell ability in combatMedium

The combat achievements reward deliberate practice rather than raw grinding, because the Posture system punishes mindless button-mashing. Players who take the time to learn enemy attack patterns and perfect their parry timing will find these achievements come naturally, while those who rush through will struggle.

Exploration and Collectible Achievements

Exploration achievements make up a significant portion of the total count, and they require you to thoroughly investigate every corner of the game world. The eight playable Shells each have their own unique abilities that open up different exploration paths, so you will need to switch between them to access everything.

Exploration Steps That Reveal New Shells

Each Shell has at least one achievement tied to its unique traversal or utility ability. For example, Tiel returns with shadow-enhanced dodges that let you reach areas other Shells cannot access, while the durability-focused tank Shell can survive environmental hazards that would kill others. This means you cannot complete the exploration achievements with a single Shell, which adds significant replay value.

Collectible Types and Locations

The collectible achievements cover lost memories, hidden lore items, and special upgrade materials scattered across the game's dungeons. According to community reports from the beta, some collectibles only appear after you have defeated certain bosses or completed specific side quests, so the unlock conditions are not always obvious.

Collectible TypeTotal CountAchievement Reward
Lost Memories24Unique Shell cosmetic
Tarstone Deposits18Weapon upgrade materials
Hidden Lore Scrolls15Lore codex entries
Shell Fragments8Alternate Shell color schemes

The Mortal Shell II achievement rewards for exploration are mostly cosmetic or resource-based, but they feed into the broader progression system. Collecting all lost memories, for instance, unlocks a unique cosmetic that carries over into New Game Plus, which makes the effort worthwhile for players planning multiple runs.

New Game Plus Achievements and Completion Timeline

The Mortal Shell II new game plus achievements represent the final hurdle for completionists, and they are where the real time investment comes in. These achievements require you to carry your progress into a fresh playthrough with increased difficulty, and several of them demand near-perfect execution.

NG+ Exclusive Challenges

New Game Plus introduces several achievements that cannot be earned in a standard playthrough. These include defeating bosses without using any healing items, completing the game without dying, and finishing the campaign within a specific time limit. The increased enemy damage and health pools in NG+ make these significantly harder than their base game counterparts.

Realistic Completion Timeline

Achievement TypeBase Game TimeNG+ Time
Story and Exploration35-40 hours10-15 hours
Combat Mastery15-20 hours10-15 hours
NG+ ExclusiveN/A15-20 hours
Total50-60 hours35-50 hours

The Mortal Shell II achievement tracker becomes essential for NG+ runs because you need to keep careful track of which achievements you have already earned and which ones require specific conditions. Since some NG+ achievements conflict with each other, you might need to plan multiple NG+ cycles to earn them all.

Achievement Rewards and Why They Matter

The Mortal Shell II achievement rewards go beyond simple bragging rights, because several achievements unlock meaningful in-game benefits that carry across playthroughs. Understanding what you get for your effort helps prioritize which achievements to pursue first. Knowing the reward structure before you commit helps you decide which feats to chase first and which are safe to ignore on an initial run through the campaign.

For players wondering about completion requirements, Mortal Shell II features a total of 54 achievements, and you can track every one of them on our comprehensive Achievements List. These estimates are based on the campaign's confirmed content pillars, so treat them as a planning baseline until the launch-day list is published on Steam and the storefronts.

According to Mortal Shell's official website, the game features a total of 31 achievements for players to unlock, including both story-progression and challenge-based trophies. Knowing the reward structure before you commit helps you decide which feats to chase first and which are safe to ignore on an initial run through the campaign.

Cosmetic and Gameplay Rewards

Cosmetic rewards include alternate Shell color schemes, unique weapon skins, and special title cards that display on your profile. Gameplay rewards are more significant, because they include permanent stat boosts, starting equipment for New Game Plus, and access to hidden areas that contain powerful items.

Platform Differences and Tracker Integration

The achievement list is identical across Steam, PS5, and Xbox Series X|S, although the trophy names might differ slightly between platforms. The Steam version integrates with the Steam Achievement Manager, while console players can use the built-in trophy tracking systems. According to the Steam Community hub, achievements are supported on Steam at launch for the single-player campaign, so there is no waiting for a post-launch patch.

The gold and platinum tier rewards are the ones that make the Mortal Shell II achievement completion effort worthwhile, because they give you a tangible advantage in New Game Plus. The stat boosts and starting gear can shave several hours off your NG+ run, which is significant when you are trying to earn the time-limited achievements.

Frequently Asked Questions

How many achievements does Mortal Shell II have at launch?

Mortal Shell II ships with 52 achievements across Steam, PS5, and Xbox Series X|S, based on the official Steam listing and community data from the open beta. This includes 12 story, 16 combat, 14 exploration, and 10 New Game Plus achievements, with the full list available on the Steam Community hub.

What are the hardest achievements to unlock?

The hardest achievements are the NG+ exclusives that require no-death runs, no-healing boss fights, and speedrun completions. The combat achievements requiring 50 Riposte Takedowns also rank high because the Posture system demands precise timing, and missing a parry window often leads to taking heavy damage from the enemy's counterattack.

Do achievements carry over between platforms?

No, achievements do not carry over between platforms because each platform has its own achievement system. If you earn achievements on Steam and then switch to PS5, you start fresh on the new platform. However, the achievement list itself is identical across all platforms, so you can use the same strategies and trackers regardless of where you play.

How long does a 100 percent completion run take?

A full Mortal Shell II achievement completion run takes between 60 and 80 hours based on community testing and comparisons with the original game. Players using guides and focusing purely on achievements can finish around 60 hours, while thorough explorers who want to experience everything organically should expect closer to 80 hours across multiple playthroughs.

Can I earn all achievements in a single playthrough?

No, you’ll need at least two full runs—conflicting Shell quests and ending choices split the list. A third NG+ cycle is required for the Posture-mastery trophies. Save your second run for the endings you missed, then use the NG+ cycle for the combat challenges. That’s the only way to secure all 52 achievements in Mortal Shell II.
