Core Keeper Playtest is a playtest associated with Core Keeper, an underground mining sandbox adventure. The parent game casts players as explorers awakening in a forgotten cavern, where uncovering its secrets shapes an open-ended journey. The playtest is a separate test product, so the parent game’s full feature set should not be assumed to be included.
Core Keeper’s documented design combines resource gathering, crafting, base building and exploration across a dynamically evolving subterranean world. Players can mine for materials, make tools and equipment, develop skills, and explore distinct biomes tied to the setting’s hidden history. Combat adds another strand: the parent game features monsters, mini-bosses and legendary Titans, with loot and character development supporting expeditions deeper underground.
Beyond delving and fighting, the game’s sandbox encompasses gardening, fishing, cooking, animal care and customization of a personal base. Its underground world also extends into areas such as the Sunken Sea, where players can build a boat, and supports solo play or online cooperative exploration. This breadth gives Core Keeper a distinctive blend of survival-adventure systems and creative home-building, with discovery and player-directed activity at its core. Playtest content may differ from the parent game.
