How to Configure Your Empyrion: Galactic Survival Server (dedicated.yaml)
Complete Empyrion dedicated.yaml reference — server name, players, EAC, telnet, scenarios, and playfield system.
Empyrion uses dedicated.yaml (YAML format) in the server root.
File Structure
dedicated.yaml
⚠️ YAML is whitespace-sensitive — use spaces, not tabs. Wrong indentation breaks the file.

Srv_Name | "" | Server name in browser |

PvP vs PvE
Empyrion uses a playfield-based system — each planet/orbit has its own PvP/PvE setting in its playfield.yaml. This is controlled by the scenario, not a single global toggle.
Ports
| Port | Protocol | Purpose |
|---|---|---|
| 30000 | UDP | Game traffic |
| 30001 | UDP | Game +1 (internal) |
| 30004 | TCP | Telnet (localhost only) |
Scenarios
Empyrion's primary mod system. Popular scenarios:
- Reforged Eden / Reforged Eden 2 — massively expanded galaxy
- Project Eden — expanded vanilla
Set via CustomScenario in dedicated.yaml. Scenario folders go in Content/Scenarios/.
EAC (Easy Anti-Cheat)
Server and client must match — if server has EAC on, players must launch with EAC enabled. Some scenarios recommend disabling EAC.
