How Long Is Mortal Shell II? Story and 100% Playtime

Plan 25 to 30 hours for Mortal Shell II's story and 40 to 50 for a completionist run, with clear reasons your playtime may vary.

Quick answer

  • 1Plan about 25 to 30 hours for a first story-focused Mortal Shell II run.
  • 2A normal run with regular detours and optional dungeons can land around 30 to 40 hours.
  • 3Use 40 to 50 hours as the current completionist target, with roughly 60 hours possible for exhaustive exploration.
  • 4Boss retries, route knowledge, build strength, and how often you leave the main path create the largest swings.

How Long Mortal Shell II Takes

Mortal Shell II takes about 25 to 30 hours for a first run focused on finishing the main story. Current completed-review estimates span 20 to 30 hours, so treat 25 to 30 hours as a planning range, not a timer.

Completion goalCurrent planning rangeWhat that assumes
Focused story25 to 30 hoursFollow major objectives and keep optional detours limited
Story plus regular exploration30 to 40 hoursCleanse extra Beacons, enter appealing dungeons, and search for useful gear
Completionist40 to 50 hoursPursue most dungeons, Shells, weapons, memories, and hidden discoveries
Exhaustive discoveryUp to roughly 60 hoursSearch every region carefully and absorb substantial retry or cleanup time

These are launch-period estimates, so individual results will spread as more players finish the game. A reported early completion took about 35 hours with heavy exploration and still left discoveries behind, which fits the middle of this range.

What the Story Estimate Includes

The 25-to-30-hour target assumes a first playthrough that keeps moving toward major objectives while taking enough nearby content to maintain a workable build. It allows for normal navigation, required fights, some equipment improvement, and a reasonable number of boss retries.

It does not assume that you clear every landmark visible from the path. Mortal Shell II uses a compact open world with more than 80 dungeons, so a player who enters every discovered branch is pursuing a different goal from a player who wants the ending efficiently.

The open beta covered an early slice of the journey. Its runtime cannot be multiplied into a reliable full-game total because the complete release adds broader regions, optional routes, build growth, and fights with highly variable retry time.

How Exploration Changes the Estimate

The world rewards wandering with new Shells, weapons, upgrades, story fragments, and curiosities. Reviewers found large regions around the central hub and side areas that were easy to enter without planning. Every optional turn buys discovery at the cost of a faster ending.

Exploration time grows through several separate tasks:

  1. Finding and clearing optional dungeons.
  2. Searching hidden passages and distant landmarks.
  3. Collecting the eight Shells and testing their playstyles.
  4. Finding and improving the sixteen melee and ranged weapons.
  5. Unlocking each Shell's memories and reading the extra story they reveal.

You can stop after the discoveries that strengthen your current build and still finish within the story range. Searching each region systematically moves the run toward 40 hours before achievement cleanup begins.

Completionist and Achievement Planning

Use 40 to 50 hours as the current target for a broad all-content run. One completed review estimates that a completionist route can take roughly twice its 20-to-30-hour story figure, which leaves room for a thorough run to approach 60 hours.

An achievement-specific completion time is still unsettled on release day. An English trophy roadmap lists its platinum duration as pending post-launch confirmation. Players who care about every achievement should therefore reserve at least the completionist range and expect the final requirement list to decide whether cleanup or another run adds more time.

For a lower-cost plan, finish the story while recording incomplete regions and obvious locked routes. Then use post-launch achievement data for targeted cleanup. That avoids spending hours on speculative tasks that may have no achievement attached.

What Changes Your Playtime Most

VariableLikely effectPlanning advice
Optional dungeon frequencyAdds steady exploration and combat timePick a rule, such as clearing only dungeons beside the current objective
Boss retriesCan add hours at a single wallChange Shell, weapon, or upgrades before repeating an unchanged attempt
Route knowledgeReduces wandering and backtrackingUse landmarks and cleared Beacons to divide each region
Build strengthStrong combinations shorten difficult encountersCount upgrade detours as time saved later when the route remains nearby
Lore and memoriesAdds deliberate reading and Shell developmentBudget this separately if story discovery is part of your goal
Guide useShortens searches and missed-item cleanupSave detailed checklists for the cleanup phase if you want a blind first run

The most efficient story run still needs enough exploration to support its build. Skipping every side route can send you into later fights underprepared, turning saved travel time into repeated boss attempts.
