Core Keeper Patch Notes — April 1, 2026
Aggregated from Steam, cross-tracked with Battle.net coverage on GamePatchNote.
Hey Explorers, we thought it was high time for another community update, especially now that you've had plenty of time to enjoy Void & Voltage. So, let's look back over the month of March and see what we've been up to...
Explorer's Guide Launch!
We launched a brand-new digital download for Core Keeper in the form of our Explorer's Guide. Perfect for beginners and returning Explorers looking for a hand-drawn guide to the underground. The Explorer's Guide features roughly 100 unique illustrations and is packed full of information, tips, tricks, lore, developer comments and more! Pick up your copy here!
1.2.1 Teaser
We showed off a little teaser of some upcoming 1.2.1 content in a video we shared on X! Chest labelling has been a highly requested feature and we're excited to add this in our upcoming Minor Content Update. Check out the video here.
Official Merch Store Launch
Speaking of community requests, it's no secret how much you've been calling out for official Core Keeper merchandise. This is something we've been in discussion about for a long time now, as we didn't want to rush into anything and risk sacrificing quality. After much planning, deliberation, and so many design iterations, we're pleased to report we launched our official merch store with a selection of awesome merch, including hoodies, T-shirts, enamel pins, socks, and a limited-edition Moolin Plush! Visit our store here.

Discord user タモチ, has been taking full advantage of the new decorative items and materials from our Void & Voltage update!
Recruitable Mobs Fan Art!
Carrockate (incredible name) shared an idea for recruitable mobs/temporary alliances along with an amazing sketch to illustrate the idea! What do you think? Would you trust a Caveling Brute enough to team up?
That's a wrap on March's community update! As always, don't forget to follow us on Discord, X, Bluesky, TikTok, Instagram, and Reddit for more Core Keeper news and announcements!
