Features
Cooperative survival focus
Survival depends on team play: share resources, split tasks and coordinate via voice to solve puzzles and manage encounters.
Voice-reactive entities
AI threats respond to sound, light and movement; vocal noise can reveal your position and trigger dangerous behavior.
Environmental puzzles
Explore abandoned camps and liminal corridors to find clues and solve puzzles that require cooperation and environmental interaction.
Sanity system
Darkness, isolation and supernatural events affect sanity; staying near light or heat slows sanity loss and influences the environment.
Tesseract Afterlife
Death leads to a surreal Tesseract realm that changes how the game continues for that character, altering post-death play.
Windows Early Access and extras
Available in Early Access on Windows (released Jun 17, 2026). Supports single-player, online co-op, Steam achievements and Family Sharing.
