Are worlds procedurally generated in Core Keeper?

Yes! Each world is unique and procedurally generated. You can also specify a seed for reproducible worlds to share with friends.

Does my Core Keeper progress save automatically?

Yes, world progress, player inventories, and all buildings are saved automatically to your dedicated server.

How much RAM do I need for a Core Keeper server?

Core Keeper is lightweight - 2GB RAM works for small groups (1-4 players), and 4GB for full 8-player servers. Larger explored areas with many entities may need slightly more.

Can I transfer my existing Core Keeper world to a server?

Yes! Upload your save files through our file manager or SFTP. Your world progress, buildings, and explored areas will transfer to the server.

How long does it take to set up a Core Keeper server?

Your Core Keeper server is ready in about 1-3 minutes after ordering. The download is small (~1GB) and we configure everything automatically. Just set your world seed and start mining!

Is there cross-platform play in Core Keeper?

Yes! Core Keeper supports crossplay between Steam and other platforms, so all your friends can join regardless of where they purchased the game.

How do I reduce lag on my Core Keeper server?

Core Keeper servers are generally stable, but very large explored areas can increase load. Restart the server periodically, ensure you have adequate RAM (4GB for 8 players), and avoid excessive entity spawning in one area.
