• Core Keeper is currently only released on Steam, but we’re definitely taking into account user feedback when it comes to other platforms. If anything changes, you’ll hear about it on our Twitter page or the official Core Keeper Discord Server.

Currently, Core Keeper is being developed with a focus on online multiplayer. If anything changes or we add any new multiplayer features, we will let you know.

Core Keeper is currently available in English, Simplified Chinese, Thai, Korean, Japanese, Spanish, and German, and we plan on adding more languages by the game’s 1.0 release. In the meantime, players can add their own custom Latin-based languages to the game.

If there is a language you’d really like to see in game, let us know in the Steam Discussions or over on Twitter or Discord!

You’ll need to navigate to your game files for this. These are different to your save files, and the easiest way to access them is to open Steam, navigate to your Games list, then find and right click the Core Keeper game. Select “Properties” from the menu that appears, then navigate to “LOCAL FILES” from the side bar. Click the “Browse…” button, and this will take you to your game files.

You should see a folder called “localization” here, open it and read the “README” file for a guide on adding custom Latin languages to the game. Please make sure you read and follow the instructions in the “README” .txt file before you start this process. Please be mindful not to delete or override the “Localization Template.csv” file when pasting your new “Localisation.csv” file into the “localization” folder.

To join a multiplayer game, one player must act as the host by booting the game, clicking “Start Game” in the main menu, and creating/loading a world. Once in game, the host should bring up the pause menu (ESC key). Here, they will find the game ID in the top-left corner of the screen. This can be copied using the “Copy game ID” button and then sent to the other players. Other players should boot the game, select “Join Game” in the main menu, and then enter the game ID to play in online multiplayer. Please note that the host must be in the world in order to play.

On windows, this can be found in C:\Users[USERNAME]\AppData\LocalLow\Pugstorm\Core Keeper\Steam[STEAM ID]

On Linux, please look to ~/.config/unity3d/Pugstorm/Core Keeper/Steam/[STEAM ID]

(Remember to replace the info in square brackets [like this] with your own, individual username and/or Steam ID).

You will also be able to find the backups folder in this location.

Please be mindful to back up data found within these locations if you inted to move/delete files or folders.

The easiest way to host a dedicated server is to use the Core Keeper Dedicated Server App in Steam. To do this, please follow the instructions below:

1. Launch Steam and navigate to your Steam Library
2. On the left-hand side of the screen, above your games list, you should see the word “GAMES”
3. Click on this to open a dropdown menu, then select “TOOLS”
4. Once “TOOLS” is selected, use the search box below this dropdown menu to find “Core Keeper Dedicated Server”
5. Right click “Core Keeper Dedicated Server” and click “INSTALL”
6. Once this has installed, launch “Core Keeper Dedicated Server”
7. Make sure “Launch Dedicated Server” is selected, and click “PLAY”
8. This should open a command window (cmd.exe), wait a few moments and this should generate a Game ID for you (if it doesn’t, hit the enter key to prompt this)
9. Your server is now running, do not close this command window. If you close this window, your server will continue to run in the background, and you will have to restart your computer to end this process
10. Run Core Keeper and join the dedicated server by entering the Game ID in the “Join Game” menu. You can distribute this Game ID to anyone you wish to play with, and they will be able to access your server while it is running

11. When you are finished running the server, navigate back to the command menu and press “q” to quit. You are now free to close the command window

On windows, this can be found in C:\Users[USERNAME]\AppData\LocalLow\Pugstorm\Core Keeper\DedicatedServer\worlds

On Linux, please look to ~/.config/unity3d/Pugstorm/Core Keeper/DedicatedServer/worlds

(Remember to replace the info in square brackets [like this] with your own username).

The Core Keeper soundtrack is being created by the very talented composer, Jonathan Geer. Find out more about him here: www.jonathangeer.com. Volume one of our soundtrack is available on Spotify here.

You can listen to the full Core Keeper soundtrack as it currently stands on YouTube by clicking here.

Core Keeper is still currently in Early Access, so DLC isn’t something the developers are currently working on.

We don’t have any announcements to make about ultra-wide support right now, but this something we’re considering for the future.

We recently made some major changes to the game’s graphics render pipeline, which we hope will improve performance as a result of less demand on device GPU. That being said, if you are experiencing issues, we recommend closing background apps when playing Core Keeper. You may also want to try going into the game’s options menu and lowering the graphics settings, as this may improve performance. We are doing our best to mitigate performance issues, and we’ll be releasing regular updates/bug fixes to address this, but please bear in mind that Core Keeper is currently in Early Access, and any performance issues encountered will not reflect the final, full version of the game.

We don’t have any plans for this mechanic at the moment, but we’ll let you know if that changes in the future.

Merchants have a specific set of requirements that must be met in order for them to move into your base. Firstly, the room must contain the specific item that the merchant wants, i.e. Slime Oil for the Bearded Merchant. The room must be no bigger than 8×8 tiles with any walls, and it must contain a bed that is not currently already taken by another Merchant. Players cannot be near the room or the Merchant for the Merchant to move in (you must be more than 30 tiles away). It should not take more than a minute for the Merchant to move in if all the requirements are fulfilled.

Players should follow the instructions for creating a room in the question above and should place the Seasonal Calendar in that room to summon the Seasonal Merchant. The room must be no bigger than 8×8 tiles with any walls, and it must contain a bed that is not currently already taken by another Merchant. Players cannot be near the room or the Merchant for the Merchant to move in (you must be more than 30 tiles away). It should not take more than a minute for the Merchant to move in if all the requirements are fulfilled.

As of the Quality of Love update, all of our seasonal events can be accessed at any time through the game’s Gameplay Settings menu. Please note that the addition of the season’s option in the game’s Gameplay Settings menu will replace the previous mechanic of having to set the season under the game’s “Launch Options” in Steam.
