I package our game so i have a MyGame.exe style result and directory.  
Then make a shortcut and add command line arguments…

MyGame.exe ?listen -server -log -LANPLAY PORT=7776

It runs and the log port shows, and the logs show it is listening on port 7776 just fine.

The problem is it also pops up a full viewport of the game nad a player is active in it.

How do I force no player and headless?

I see the posts on building a server from scratch, but shouldn’t -server just do this?

The argument **listen** has you start a client that also acts as a server. I believe you simply have to remove that argument if you want just a dedicated server.

Turns out that it is a case of RTFM.

Hey there, in order to put the game into headless mode, you need to include the arguement -NullRHI along with the

```
MyGame.exe ?listen -server -log -LANPLAY PORT=7776

```

This would look like

```
MyGame.exe ?listen -server -log -NullRHI -LANPLAY PORT=7776

```

Now, in order to be able to run the game without a player, I believe you may need to override the GameMode and specify there for something like spectator only?

But I don’t believe this is what you’re looking for. I believe that you are looking for something like this guide: [A new, community-hosted Unreal Engine Wiki - Announcements - Unreal Engine Forums](https://wiki.unrealengine.com/Dedicated_Server_Guide_%28Windows_%26_Linux%29)
