I wrote a guide to setting up an alternative to using a dedicated server. This allows any player to host at any point. The core idea behind this revolves around using git to automatically sync worlds. Player A: Runs a launch .bat - Pulls the latest from the repository - Valheim is launchedPlayer A: Starts a server with the synced world Player B: Launches Valheim from Steam Player B: Joins the Game Player C: Joins the Game Player D: Joins the Game All Players play as much as they want Player A: Closes the game - Pushes the world’s changes to the repository To start another session, any of the players can follow these steps.
