Mortal Shell II

Mortal Shell II is a dark fantasy action role-playing sequel developed by Cold Symmetry and published by Playstack. Released on August 20, 2026, for PC (Steam), PlayStation 5, and Xbox Series X/S, the game expands upon the original's atmospheric soulslike foundation by introducing a high-tempo unrestricted combat system without a traditional stamina bar, eight diverse playable warrior Shells, deep socketable Tarstone customization with over 75 unique modifiers, and a vast interconnected open world encompassing shattered landscapes, bone-carved citadels, and over 60 multi-tiered dungeons. Players embody the Harbinger, an entity born from the crashed celestial Undermether, embarking on a perilous quest to reclaim scattered divine Ova and purge the spreading eldritch corruption across Fallgrim and the Marrow Keep.

• Unrestricted Fluid Combat: The sequel eliminates the traditional stamina bar entirely, transitioning to a high-tempo combat philosophy where aggression, fluid combos, agile repositioning, and precision hardening timing dictate survival.
• Eight Playable Shells: Discover and inhabit 8 distinct fallen warrior Shells (including Tiel the Acolyte, Proxima the Broodseeker, Sester Genessa the Wayward, and Lazlo the Justiciar), each featuring tailored stat profiles, active Shell skills, and unlockable memory perks.
• Dynamic Hardening & Posture Shatter: Turn your physical form instantly to unbreakable stone mid-swing, mid-air, or during recovery to deflect crushing blows and stagger foes, building up posture break meters for devastating execution ripostes.
• Tarstone Infusion Matrix: Collect and equip up to 10 Tarstones across five functional categories (Support, Combat, Infusion, Ability, Fragile) to heavily customize weapon properties, status afflictions, critical modifiers, and passive perks.
• The Undermether & Celestial Ova: Explore a sprawling, interconnected dark fantasy world with over 60 dungeons to reclaim the stolen Ova of the fallen celestial Undermether, purifying corrupted sacred grounds.
• Mether's Pulse & Mether's Breath: Tap into divine eldritch energy fueled by combat Resolve to mend wounds on the fly or unleash cataclysmic elemental bursts that wipe out enemy hordes.
• Dual-Form Transformable Weaponry: Wield versatile combat instruments like the Axatana (shifting between twin axes and a massive nodachi) and heavy ranged siege weapons like the Ballistazooka Mark II.
