RimWorld has no multiplayer of its own, so your RimWorld server runs a multiplayer mod. Every player keeps their own colony on one shared planet, and players can trade with, visit and raid each other. Your server runs one of two mods, shown as the game of your server in Bropanel, so follow the section for yours.

Your server	Players need
RimWorld Together	RimWorld 1.6 on Steam, with the RimWorld Together and Harmony mods
Open World	RimWorld 1.4 on Steam, with the Open World, Harmony and HugsLib mods

Tip

We recommend RimWorld Together. It is updated regularly, while Open World was abandoned in 2023 and only works on RimWorld 1.4.

Connecting to a RimWorld Together Server

Installing the Mod

1
Subscribe to RimWorld Together and Harmony on the Steam Workshop.
2
Start RimWorld, click Mods, and turn on both mods.
3
Put Harmony at the top of the list, then Core and any DLCs, then RimWorld Together.
4
Close the mod list and let RimWorld restart.

Every player needs the same RimWorld Together version as your server. Your server installs the newest release when it restarts and Steam keeps the mod up to date, so restart your server after a new RimWorld Together release. If a player sees This server requires version, restart your server, then have the player restart Steam so it updates the mod.

Joining With the IP Address

1
Log in to Bropanel and select your RimWorld server.
2
Copy the server IP address and port from the Overview page, for example 123.45.67.89:25555.
3
Start RimWorld and click Direct Connect on the main menu.
4
The first time, create your RimWorld Together account with a username and password.
5
Enter the IP address in IP and the port in Port, then click Connect.
6
If your server has a password, enter it when asked.

Note

The first player to join sets up the world for your server. Until that is done, other players see Server is currently being set up! Join again later!.
