In Core Keeper, a mining sandbox adventure, players are drawn toward 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.

Pugstorm and Fireshine Games are excited to invite Steam players to check out Core Keeper for free this weekend, letting explorers begin their underground adventure ahead of the game’s 1.0 launch next week.

Available from 6pm BST today until August 26th, Core Keeper’s Steam Free Weekend lets players discover the award-winning sandbox adventure for free, with the option to select Classic Worlds for complete access to the current Early Access version of the game and – for the first time ever – 1.0 Worlds to get an early look at some of the exciting new content coming with next week's 1.0 Update.

Discover the new Mage and Warlock combat playstyles and check out the powerful new world generation tool, one of the major new features coming with Core Keeper’s 1.0 Update, to customise your worlds with various parameters and geometry. Get a head start on your new 1.0 World, building your base, gathering resources, levelling up your character, exploring diverse biomes, and taking on the opening bosses ahead of the game’s full 1.0 launch next Tuesday, August 27th.

Anybody who purchases the game will be able to carry over any worlds, characters and game progress made during the Steam Free Weekend to the full 1.0 release when it launches on August 27th. (Please note: Players are strongly recommended to start with 1.0 Worlds to continue story progression following the launch of the 1.0 Update. Classic Worlds are included in the Free Weekend to experience Core Keeper's full Early Access content, but will not support critical content introduced with next week’s 1.0 Update.)

Players who currently own Core Keeper on Steam Early Access will also be able to access the new world generation feature and combat playstyles during the Steam Free Weekend, giving them a head start to build new 1.0 Worlds and discover new features ahead of the 1.0 Update.
