The V Rising Dedicated Server is the server application for the game V Rising (Steam, Playstation 5).
There is a server packaged with the client, which runs in the background when you start a local private game from within the game client, but these instructions are for when you want to download and run your own dedicated server.
There are currently four (4) different versions of V Rising, and therefore also of the V Rising Dedicated Server. Follow the below link for the version you are interested in.
