Core Keeper is a co-op sandbox adventure set in a vast underground world where you mine, build, and survive around a mysterious ancient Core. Dig through procedurally generated caverns, uncover biomes and relics, and turn scattered resources into a thriving base. Face towering bosses, craft powerful gear, and automate your outpost with rails and electricity. Farm, fish, and cook to gain buffs, level up skills through play, and restore the Core’s power to unlock new areas and technologies. Play solo or with up to 8 players for a cozy yet challenging blend of exploration, survival, and base-building.
Explore sprawling underground biomes to discover resources, secrets, and new challenges. Mine ores, gems, and ancient loot to craft tools, weapons, and structures. Build and expand a secure base around the Core, restoring its power to unlock new zones and systems. Craft and upgrade armor, tools, and gadgets, then automate logistics with rails and electrical circuits. Fight creatures and thematic bosses using melee or ranged weapons while leveling combat and utility skills. Team up in online co-op to divide roles, share resources, and tackle tougher areas together.
