Core Keeper is an underground sandbox adventure where players mine, build, fight, and farm in a mysterious subterranean world. This cooperative survival game supports up to 8 players working together to explore procedurally generated caverns, defeat ancient bosses, and uncover the secrets of the Core.
Whether you are hosting your own server or joining friends, connecting to your world is incredibly simple. Let us get you and your squad connected for some underground exploration!
The unique Game ID can also be seen in the Esc menu while you are actively connected to the server. You can share this ID with your friends to let them join quickly!
Step 1: Access Your Server Panel
- Navigate to the MintServers Dashboard at
https://mintservers.com/dashboardand log into your account. - Click on your Core Keeper server from the list and select Open Game Panel.
Step 2: Locate Server Connection Details
Core Keeper handles connection details a little differently than most games. Instead of a standard IP and Port on the console, it generates a specific text file containing your server credentials.
- Navigate to the Files tab on the left-hand menu.
- Locate and click on the
GameInfo.txtfile to open it in the editor. - Copy the server information from this file, including the IP, port, and password.
Step 3: Launch Core Keeper and Join
- Open Core Keeper on your computer and wait for the game to fully load to the main menu.
- From the main menu, choose the Join Game option.
- Paste in the IP, port, and password you copied from Step 2 into their respective fields.
- Click Join. Your Core Keeper client will connect to the server, and you can begin your underground adventure!
🛠️ Troubleshooting Connection Issues
- Server Offline: Ensure your server is actually running and shows as "Online" in the MintServers game panel before trying to connect.
- Typo in Details: Double-check that you copied all information correctly from the
GameInfo.txtfile without accidentally adding any extra spaces. - Password Issues: Verify the server password matches exactly. Passwords are completely case-sensitive!
- Server Full: Make sure the server isn't full (Core Keeper has a default maximum of 8 players).
- Version Mismatch: Check that your local Core Keeper game is fully updated and matches the version currently running on the server.
