Core Keeper

Core Keeper is a mining sandbox adventure for 1–8 players. You awaken as an explorer in a long-forgotten cavern and shape your journey by harvesting resources and relics, crafting tools, building a base and exploring a world that evolves as you uncover it. You can play solo or explore with others.

Explore the underground

The underground has diverse biomes, each with its own ecosystem and long-forgotten lore. Explore the living walls of the Clay Caves and the crystal caverns of the Shimmering Frontier, uncover the secrets of the Cavelings and find remnants of ancient civilizations. Build a boat to travel across the Sunken Sea or race across the Desert of Beginnings.

Mine and craft

Harvest precious resources and hidden gems, then craft tools and equipment to help you survive. These include pickaxes, fishing rods, shovels, traps, bombs and mortars, as well as advanced tools such as the Obliteration Ray. Automated machinery can streamline mining, smelting and storage. Level up your skills and unlock powerful weapons as you explore deeper.

Build and make a home

Build a base from a variety of materials and customisations, whether you want an adventurer’s lair or a cozy underground cottage. Customize your character’s appearance and choose from armor and outfits to suit the moment. You can also grow a garden, fish, master recipes, and raise and care for animals.

Battle the Titans

Fight monsters and mini-bosses as you sharpen your combat skills and spend talent points to improve your abilities. Plan your approach to confront the legendary Titans, who hold secrets about the underground world. Find rare and powerful loot and use it to power up the Core.

Play together

Online co-op supports 2–8 players and allows players to drop in and out. Explore at your own pace, trade with merchants, hatch companions, design a base, automate resource gathering, host a dedicated server, play music on instruments and celebrate the seasons.
