How to Change Max Players on Your Space Engineers Server

Set the player limit on your Space Engineers dedicated server.

The default Space Engineers player limit is 4. Most servers run 8–16 players.

Stop your server

Go to Console in the XGamingServer Panel and stop the server.

Open the config

Click Files in the sidebar and open SpaceEngineers-Dedicated.cfg.

Change MaxPlayers

Find and change:

<MaxPlayers>16</MaxPlayers>

MaxPlayers also exists in Sandbox_config.sbc (the per-world config). For an existing world, you may need to update it there as well — the world-level setting takes priority.

Save and start

Click Save Content and start from Console.

Performance Impact

Each additional player adds load from:

Physics simulation for their grids
Network sync traffic (controlled by SyncDistance)
Entity tracking and AI

If lag increases at higher player counts, lower SyncDistance, reduce TotalPCU, or lower MaxFloatingObjects. See the server configuration guide for all performance settings.
