The Phi Mod allows multiplayer interactions between players’ colonies such as chatting and sending resources from one player to another.
Phi Mod features
With the Phi Mod you can connect to the global default server or host your own server to play with your friends. It doesn’t matter whether you are playing via Steam or not.
New features are added with every update, but currently the Phi Mod will allow you to perform the following multiplayer actions:
- Chat with the connected players in real time.
- Send pods containing items from your colony to other players. They will receive the items on their own colonies.
- [Experimental] Send your own colonists to another player’s colony.
How to play RimWorld multiplayer with the Phi Mod
After enabling the Phi Mod, load a game and a new button named “Server” will be available at the bottom-right of the screen to open up a chat. This chat will list all the players that are available on the server.
Click on the nickname of another player to send items to him.
How to set up your own RimWorld Multiplayer server
Download the server setup file and place it anywhere on your computer. Launch PhiServer.exe using a shell (so you get the server logs in case of an error). The server can also be hosted on a Linux server (longwelwind.net is hosted on a Ubuntu Server machine) using mono.

You can enable multiplayer on previously saved games, but it is recommended to back up the save file before attempting to use the Phi Mod.
