Mortal Shell 2 発売: プラットフォームと価格

What launched, and when

Mortal Shell II launched worldwide on August 20, 2026, developed by Cold Symmetry and published by Playstack. It is a standalone sequel — a complete premium release rather than an Early Access or episodic launch — and it shipped simultaneously on PC (Steam), PS5 and Xbox Series X|S.

The official website carries the launch messaging, including pages localised into Simplified and Traditional Chinese, and the official launch trailer was published alongside release.

How the launch window went

SteamDB records an all-time peak of approximately 44,486 concurrent players on August 23, 2026 — the first weekend after launch, which is a healthier curve than a day-one spike followed by a collapse. A 24-hour peak around 23,527 was recorded at the time this page was verified, indicating the player base held rather than evaporating.

Critically, the reception has been broadly positive: Mostly Positive on Steam at roughly 78% positive across about 5,608 reviews. Reviews describe the game as a confident step forward for the series, with the Shell system still the standout feature and the world described as dense, readable and rewarding to explore.

Day-one patch and Balance Patch 1

Pre-release coverage noted that a day-one patch was expected to target several technical issues present in review builds — camera behaviour, lock-on drift and related problems.

Since launch, Balance Patch 1 has shipped. It is confirmed to cover economy changes, boss and enemy nerfs, weapon buffs and Tarstone buffs, and to roll out on both PC and console. That is four of the five major progression systems adjusted within the first week, so expect build advice written at launch to be outdated already.

Known issues at launch

The community bug megathread that opened at global release covers crashes, NVIDIA shader-cache guidance, controller issues, missing rewards, quest softlocks and combat bugs, along with workarounds. The two most widely reported gameplay problems are:

• Camera spinning, which players fix by exiting to the main menu and reloading the save.
• Lock-on drift, where attacks rotate clockwise around the locked target and miss — including ripostes. Switching from immersion mode to action mode usually resolves it.

Neither is universal, and both were expected to be addressed by patching. See the Crashing page for the full troubleshooting checklist.

Was there pre-release access?

A community thread describing a full completion refers to Advanced Edition access, which confirms a pre-release build was distributed to some players. That is not a public beta, and no public demo has been confirmed by any official source.

What is not part of the release

• No co-op or multiplayer. Steam lists the game as single-player only, with offline achievements.
• No PS4 or Xbox One version. Confirmed — the release is PC, PS5 and Xbox Series X|S only.
• Game Pass: not currently available. Confirmed against Xbox and PC Game Pass listings.
• PS Plus: not confirmed. No official catalogue evidence either way.
• Mod support: not confirmed. No official tools announcement — note this is "unconfirmed", not "no".
• Public demo: TBD. Note that an open beta is confirmed, which is a different thing.

NG+ and post-launch support

NG+ exists, which matters for anyone planning a completionist route: bond-gated milestones can be finished on a second pass rather than optimised into one run.

Balance Patch 1 has shipped on PC with console rollout following, and the notes confirm a larger patch is already in testing. Patch support began within the first week of launch, which is a strong signal for the game's longevity — and the reason every page here carries a last-verified date.

Where to play

The safest place to buy is the official Steam page, or the platform store for PS5 and Xbox Series X|S. When buying keys from third-party resellers, check region locks, additional fees and seller reputation before activating.

Still unconfirmed

Regional unlock times (deliberately left as TBD — a wrong unlock hour is worse than none), edition contents, pre-order bonuses, any collector's or physical edition, PS Plus inclusion, and the full verbatim Balance Patch 1 changelog. All TBD.
