LONDON, UK – June 12, 2021 – Sold Out and Pugstorm are delighted to announce Core Keeper, a new mining sandbox adventure coming to Steam Early Access later this year.

Drawn towards a mysterious relic, you are an explorer who awakens in an ancient cavern of creatures, resources and trinkets. Mine relics and resources to build your base, craft new equipment, survive, and power up the Core. Defeat giant monsters, discover hidden secrets, farm crops, cook new recipes and explore a procedurally generated underground world in a mining sandbox adventure for 1-8 players.

For the first look at Core Keeper, watch the brand new announcement trailer or check out an extended look at gameplay, where animator Sven Thole and game designer David Lindqvist give players an in-depth look at the game’s systems and exploration-based gameplay.

Power up the Core - Build workbenches and generators to craft new equipment and technology, create your base, and power up your Core.

Craft items & equipment - Customise your explorer and craft new items, armour and equipment to venture further into the cave.

"We have had the concept of Core Keeper in the back of our minds for a long time now and are excited to finally reveal the game today,” said Sven Thole, CEO & Animator at Pugstorm. “We’ve had a lot of fun playtesting the game within the development team and are looking forward to welcoming the community into the world of Core Keeper in the future."

Core Keeper’s blend of mining, farming, crafting, base-building and co-op adventuring has all the hallmarks of a modern favourite, so we can’t wait to see the community’s response when the game launches in Steam Early Access later this year,” added Vincent Coates, Product Manager at Sold Out.

Core Keeper will be available on PC via Steam Early Access in 2021, and can be added to your Steam Wishlist now. For more information on Core Keeper, follow @CoreKeeperGame on Twitter and join the discussion on Discord.
