# How to Configure Your Empyrion: Galactic Survival Server (dedicated.yaml) (/docs/empyrion-galactic-survival/server-config)



import { File, Folder, Files } from 'fumadocs-ui/components/files';

Empyrion uses `dedicated.yaml` (YAML format) in the server root.

PvP vs PvE [#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 [#ports]

| Port  | Protocol | Purpose                 |
| ----- | -------- | ----------------------- |
| 30000 | UDP      | Game traffic            |
| 30001 | UDP      | Game +1 (internal)      |
| 30004 | TCP      | Telnet (localhost only) |

Scenarios [#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) [#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.
