The underground is just teeming with untold secrets, so we’ve created this official guidebook for explorers who really want to get to grips with all things Core Keeper. From the start of your adventure all the way to late-game content, you’ll find everything you need to know alongside official lore drops, top tips, fun facts, and 100 hand-drawn illustrations.
Whether you’re setting out on your first expedition or you’ve been with us since day one of Early Access, you’ll discover a wealth of knowledge and information in the Explorer’s Guide – including detailed information on the underground’s various creatures, biomes, and resources. We even reached out to our community members and ambassadors for top-tips for your adventures and build recommendations!
To top it all off, we've included a bunch of original concept art and official key art alongside the Explorer's Guide. We hope you enjoy looking back over the artwork and ideas we've conceptualised over the years.
