When Did the Mortal Shell II Open Beta Start?

Open beta launch dates

The Steam date comes from the Steam store page (release date "5 Jun, 2026") and the official announcement "Now Available: The Mortal Shell II Beta" (June 5, 2026). The console date comes from the PlayStation Store (Release 7/31/2026), the Xbox store page ("31 Jul 2026"), and the official news post "Mortal Shell 2's Open Beta Starts Today" (July 31, 2026).

Fextralife lists the Steam beta as "released on June 6, 2026." The difference is treated as a timezone artifact — June 5 in the US is June 6 in some regions — with the official June 5 date used here.

Start times and timezone details

No official announcement gives a specific start clock time for the open beta on either platform; the official sources confirm launch dates only. Time-of-day evidence comes from observable signals:

• PlayStation published its "Beta Available Now" trailer on July 31, 2026 at 06:00 PDT, the morning of the console beta launch (YouTube metadata).
• A major live stream of the Steam beta began on June 5, 2026 at 20:27 PDT, the evening of the Steam launch (YouTube metadata).

These signals are consistent with the beta going live on June 5 (Steam) and July 31 (consoles) in US time, but they are not official start times.

Full game release times (context)

Pages that rank for "open beta time" mostly document the retail release schedule rather than the beta. Those times apply to the full game and are included here for context.

Game Rant reports a simultaneous global launch on August 20, 2026 at 9:00 AM ET, with Devout Edition advance access beginning on August 17 at 1:00 PM UTC (up to 72 hours earlier). Game8's timezone table gives the same August 20 unlock at 13:00 UTC, and a Steam community post lists the Devout Edition as "6am PDT 8am CDT 9am EDT 1pm [UTC]" on August 17. The conversions agree (9:00 AM EDT = 13:00 UTC).

These times come from third-party guides (Game Rant, Game8) and a Steam community post; official news confirms the August 20 worldwide release and the 72-hour early-access framing but not the exact clock times.

Platform differences

The Steam (PC) beta launched first, on June 5, 2026, and was listed as a demo (type=demo) on the Steam store. The PS5 and Xbox Series X|S betas launched together on July 31, 2026.

Fextralife notes the beta "can be accessed for a limited time." The open beta ended before the full release; the official sources do not document a specific end date or end time.

Current status

The Mortal Shell II open beta is over. The full game released on August 20, 2026 and is the current version; there is no open beta to join or download.
