Important Information About Upcoming Modding Changes (Steam Workshop!)

Greetings Explorers! We know you are all very excited for 1.2, and we can't wait for you to experience this major content update in January. For now, we have something else exciting to share: Steam Workshop and notable modding updates!

(Note that these updates will first be introduced to the ambassador program before being publicly accessible as a beta. Mod creators can learn how to join the ambassador program in the "Closed Beta for Ambassadors" section below.)

[h2]🛠️ Modding Changes[/h2]
Our goal is to make mod creation more accessible for newcomers while also giving experienced creators more powerful tools for deep customization.

Here's a short list of what will be possible with the tools released with 1.2:

  • Easily replace in-game textures and colors for player looks and armor.
  • Reskin and recolor existing non-player sprites: including pets, cattle, workbenches, and most other assets. (Texture packs, anyone?)


Full documentation and a "getting started" guide will launch alongside 1.2.

[h2]đź§­ Steam Workshop[/h2]
We are adding support for Steam Workshop! Initially, it will launch as a closed beta for ambassadors. With the release of version 1.2, the Workshop will be available to both mod creators and players as an opt-in beta.

Our main goal is to improve the tools based on community feedback. Once we are confident it's ready, we will remove the beta and opt-in requirements in a future update.

Starting with 1.2, the modding SDK will include Steam Workshop as a built-in upload option. We will also release a few example mods to showcase the new workflow. To access the Workshop once 1.2 is out, you will need to join a Steam Group. The link and details will be shared in the 1.2 release announcement.

[h2]đź§Ş Closed Beta for Ambassadors[/h2]
As mentioned, the new modding features will first roll out as a closed beta for ambassadors.

If you are a mod creator and would like to sign up, follow the instructions below and mention that you are a mod creator, including links to your previous work. (Mods for other games are perfectly fine to include!)

If approved, you will receive detailed instructions on how to access everything.

[h3]✨ How to Join Our Ambassador Program[/h3]

Core Keeper ambassadors are creators, and we share builds and assets to enable them to create Core Keeper content like videos, livestreams, fan art, and even mods! We love seeing folks enjoy our game, and anything you put out into the world about Core Keeper puts a big smile on the developer’s faces.

Why Become an Ambassador?
As a Core Keeper ambassador, you'll receive early access to new updates and a special creator kit, which includes SFX, music, and exclusive assets. Additionally, you also have an informal line to our developers to share feedback and ask questions leading up to the update you'll be getting access to!

Can Anyone be an Ambassador?
Our Ambassador program is open to applications from all kinds of creators. While we won’t be able to guarantee an invitation for everybody who applies, there’s no strict criteria around what type of creators we're accepting, so long as you're passionate about Core Keeper and love what you do. Whether you're a content creator, mod creator, artist, or something else, if you'd love the opportunity to actively create content around Core Keeper, we’d love for you to apply!

If you're interested in becoming an Ambassador, you can APPLY HERE.

[h2]đź’¬ Feedback & Questions[/h2]
We're best suited to handle feedback and questions over on our official community Discord in the mod creators channel. We will do our best to reply to everyone! You can also tag the developer, Rupas, directly, as he is the one who implemented these changes.

If the mod-creators channel is hidden for you, please check out the opt-in button on Discord here.

We can't wait to see what amazing mods you create! 🙂

Fantastic co-op sandbox Core Keeper is adding an explosive new biome and boss for free

We're spoiled for choice when it comes to the best sandbox games that you can play with friends. But while it's easy to fall back on big names like Minecraft, Terraria, and Stardew Valley, I'd recommend gathering your group for a few sessions of Core Keeper. Launched out of early access in 2024 to a 94%-positive Steam reception, it's a very worthy addition to the collection, and it's about to get even bigger. Developer Pugstorm has just unveiled its next update, Void and Voltage, which adds a new biome, dungeon, and boss to discover, and it'll be arriving for free in January.

Core Keeper's “Void & Voltage” is Launching January 28th 2026!

We’re positively buzzing with excitement to let you know that Core Keeper’s next major content update, Void & Voltage, is coming on January 28th 2026! We had a lot of ambitious ideas for this one, which we’ve added along with plenty of community requested features. Read on to find out what’s coming your way early next year.

[h2]New Biome Beyond the Passage![/h2]
Those of you who have made it to the outermost regions of the underground might have thought that you’d reached the end of the world. Well, that’s the thing about ancient underground caverns…just when you think you’ve explored everything, something new and exciting crops up on the horizon!

Welcome to Breaker’s Reach. This brand-new biome is bristling with untold secrets and inorganic life. Navigating this mechanical world won’t be easy, with Chargers, Patrollers, and Swarmers protecting the valuable resources within, but it’ll be worth the challenge for access to new tools, weapons, gear sets, and crafting materials!

[h2]Meet S.A.H.A.B.A.R[/h2]
We weren’t about to reveal a whole new biome without giving you a cool new boss and mysterious dungeon for you to explore. If you’ve ever wanted to re-create your favourite anime scenes and battle a GIGANTIC robot, then you’re in luck! S.A.H.A.B.A.R is a machine straight out of your nightmares with laser-targeted energy beams and special abilities that’ll put your timing to the test!

[h2]Automation for the Nation[/h2]
With a machinery-focused new biome and more robots than you can shake a Solarite Sword at, you’re gonna have your hands full of mechanical parts. If only there were new and exciting automation features to craft with them…Introducing the Advanced Automation Table, an all-new workbench that’s set to make your lives easier from here on out!

Whether you’re looking to streamline gardening with the new Seed Extractor and Robot Farm Arm, or you’re ready for new and improved salvaging and item disposal, this handy workbench has a whole host of new crafting recipes just waiting to be uncovered. There are oodles of new automation systems and electronics coming to Void & Voltage, such as new generators, critter catchers, proximity sensors, and more!

[h2]“Fire in the Hole!”[/h2]
You can expect lots of new gear with this update, Explorers, including miniguns, mortars, grenades, and even remote detonators. Oh, and did we mention the new flamethrower? You’ll light up the underground with this handheld weapon…just watch out for oil barrels, rumour has it they can get a little explode-y around fire. We’re also adding a bunch of new decorative items, armour sets, new off-hand items and accessories, and an all-new minion and tome. We could spend forever listing all the new additions, but we think it’s much more fun to go out and discover them for yourselves! Be careful, though – we weren’t kidding about the oil.



[h2]Void Sub-Biome[/h2]
There’s something strange occurring in the underground where the very fabric of spacetime seems to warp and tear, creating an otherworldly new sub-biome filled with threatening variations on some familiar enemies. Expect to cross paths with Void Larvae (emerging from Void Coccoons!), Void Cavelings, Void Shaman, and Void Brutes! These enemy variants use a never-seen-before combat mechanic, allowing them to make special attacks such as explosive flames, spinning arcane beams, and lightning orbs! We’re very keen to hear what you think of this all-new system and if it is something you’d like us to continue developing. Keep your wits about you, Explorers. Standard enemy variants aren’t the only things that have crossed the void…beware the Void Hydra!



[h2]And More[/h2]
Echo maps that are used to locate important areas within the world (we know you’ve been asking for this one!), 6 new crafting statues with waypoints, a whole host of new scenes, new achievements, new paintable items, minion improvements, the ability to break previously indestructible items…the list goes on. We’ll share the full patch notes when the update launches on January 28th 2026!

We can’t wait to hear what you think of Void & Voltage when it launches on January 28th. In the meantime, be sure to keep an eye out for more insights and info about the new update over on the official Core Keeper community Discord, X, Bluesky, and Instagram accounts!
