Core Keeper server hosting
Underground co-op for up to 8 friends. Players join with a Game ID, no port setup.
What you get
- Game ID shown in the console
- World name, seed and mode from the panel
- Low memory use
- A free 10-slot Mumble voice server to go with it (one per account)
No ports, no router settings
The server runs on our machines, not yours. It gets a port of its own on our address, so there is nothing to forward on your router, nothing to leave open overnight, and your home connection is never handed out to players. Your upload speed stops being the thing that decides how many people can join.
