After nearly two years in Steam Early Access, Soulmask has officially launched version 1.0, described by developers CampFire Studios and Qooland Games as a "complete reinvention of the game itself." The update introduces substantial changes including a new onboarding flow, refreshed combat mechanics, tribal AI system, and settlement management features. Players can now access the Mask Knowledge Base encyclopedia without leaving the game.

The 1.0 version expands with three distinct game modes: Survival for the classic challenge, Tribe Mode for civilization building and political threats, and Warrior Mode for combat-focused players with tougher enemies and durable weapons. The update also introduces the Mask Mimicry Ascension system, expanding the capabilities of the game's masks beyond previous limits and adding more endgame content.

Coinciding with the 1.0 launch is the "Shifting Sands" Egypt DLC, free for the first month after release. Players can explore Egyptian deserts, ruins, and oases while facing Sand Bandit factions and their ancient technology. After defeating the Egyptian crocodile deity Sobek, players gain the ability to build flying ships that serve as moving bases, which can be linked to form flying fortresses and shared via Steam Workshop.
