About the Demo
WELCOME TO MORTAL SHELL II
The Mortal Shell II Open Beta grants access to the opening hours of the full game, from the Prologue into the first explorable region.
Players will begin the Harbinger’s journey by possessing fallen Shells and venturing into an early section of the open world. Along the way, you can cleanse beacons, explore optional dungeons, take on hidden mini-bosses and challenges, then press onward toward Magdalena, the Lady of the Woods.
This is an in-development build, so you may encounter bugs, performance issues, or other rough edges as we continue polishing the game. We appreciate your patience and encourage you to report any issues through our dedicated Discord channel:

PROGRESS CARRY-OVER
Play the Mortal Shell II Open Beta to unlock The Flayed Harbinger, an exclusive cosmetic reward available to claim in the full game at launch.
Players who progress beyond the Marrow Keep will also unlock the option to skip the Prologue in the full game.
To preserve the balance of the full release, beta save progress will not carry over in full. Currency, weapons, Shells, collectibles, and other items discovered during the Open Beta will reset at launch.
ARISE, HARBINGER
Awaken as the Harbinger, a prophesied being sent to reclaim the blessed Ova of the Undermether from the zealots and abominations that now guard her unborn kin.
In the Open Beta, players can discover Tiel, the Acolyte, one of Mortal Shell II’s eight playable Shells. Seek his remains, possess his flesh, awaken his innate abilities, and uncover the secrets buried within him.
