Every planet or sector that players are on runs as its own playfield server process. The number of occupied playfields decides the load more than the player count. | Feature | **Small crew** Up to 4 players | Recommended **Community** Up to 10 players | **Large** Up to 20 players | **Big scenario** More players or Reforged Eden | | --- | --- | --- | --- | --- | | Memory (RAM)Each occupied playfield runs in its own process, so memory grows when players spread across the galaxy. | 8 GB | 12 GB | 16 GB | 24 GB+ | | CPU coresSeveral playfield processes run at once, so more cores help as players spread out. | 2–4 | 4 | 4–6 | 6+ | | Disk spaceThe server download is about 19 GB; saves and scenarios come on top. | 35 GB | 40 GB | 50 GB | 60 GB+ | | Reserve playfieldsSrv\_ReservePlayfields keeps spare playfield servers ready so players do not wait when they warp. | 1 | 1–2 | 2 | 2+ | | Typical use | Friends in the default galaxy | A community on one scenario | A busy public galaxy | Large scenarios such as Reforged Eden | - ### Small crew Up to 4 players Memory (RAM)Each occupied playfield runs in its own process, so memory grows when players spread across the galaxy. 8 GB\ CPU coresSeveral playfield processes run at once, so more cores help as players spread out. 2–4\ Disk spaceThe server download is about 19 GB; saves and scenarios come on top. 35 GB\ Reserve playfieldsSrv\_ReservePlayfields keeps spare playfield servers ready so players do not wait when they warp. 1\ Typical use Friends in the default galaxy - Recommended ### Community Up to 10 players Memory (RAM)Each occupied playfield runs in its own process, so memory grows when players spread across the galaxy. 12 GB\ CPU coresSeveral playfield processes run at once, so more cores help as players spread out. 4\ Disk spaceThe server download is about 19 GB; saves and scenarios come on top. 40 GB\ Reserve playfieldsSrv\_ReservePlayfields keeps spare playfield servers ready so players do not wait when they warp. 1–2\ Typical use A community on one scenario - ### Large Up to 20 players Memory (RAM)Each occupied playfield runs in its own process, so memory grows when players spread across the galaxy. 16 GB\ CPU coresSeveral playfield processes run at once, so more cores help as players spread out. 4–6\ Disk spaceThe server download is about 19 GB; saves and scenarios come on top. 50 GB\ Reserve playfieldsSrv\_ReservePlayfields keeps spare playfield servers ready so players do not wait when they warp. 2\ Typical use A busy public galaxy - ### Big scenario More players or Reforged Eden Memory (RAM)Each occupied playfield runs in its own process, so memory grows when players spread across the galaxy. 24 GB+\ CPU coresSeveral playfield processes run at once, so more cores help as players spread out. 6+\ Disk spaceThe server download is about 19 GB; saves and scenarios come on top. 60 GB+\ Reserve playfieldsSrv\_ReservePlayfields keeps spare playfield servers ready so players do not wait when they warp. 2+\ Typical use Large scenarios such as Reforged Eden Eleon publishes no server hardware figures; these starting points count one process per occupied playfield and grow with large scenarios. ## Scenarios, playfields and administration The dedicated server reads its settings from a dedicated.yaml file and starts playfield servers as players need them. ### dedicated.yaml Server name, password, player limit, public listing and save folder, plus the game name, mode, seed and scenario. ### Workshop scenarios Point CustomScenario at the scenario folder; SharedDataURL lets players download its shared data from a link. ### Playfield servers Each occupied planet or sector runs as its own process; Srv\_ReservePlayfields keeps spares ready. ### Empyrion Admin Helper The admin tool that comes with the server; use it while the server is stopped. ### Easy Anti-Cheat EACActive switches EAC on or off; EAC only works on Windows servers. ### DLC content EnableDLC: true makes the Dark Faction scenario and other DLC content available on the server. ## Set up your Empyrion server Four steps from the first choice to the first warp. 1. ### Pick a scenario and size The default galaxy or a Workshop scenario: choose the size with the table above. 2. ### Pick a location Choose the one closest to your players from our 20 game server locations. 3. ### Write dedicated.yaml Set the server name, password, player limit, game name and scenario, then add your admins with the Empyrion Admin Helper. 4. ### Join the galaxy Players find the server in the multiplayer browser or join with its address. ## Other game servers you might like [See every game](https://hyperdc.com/game-server-hosting) [See all survival servers](https://hyperdc.com/game-servers/survival-game-servers) ### Space Engineers Persistent worlds with PCU limits, mods and console crossplay.

[Contact us](https://hyperdc.com/contact-us) [Open a ticket](https://hyperdc.com/support/new-ticket) ### Which ports does an Empyrion server use? The GamePort set in dedicated.yaml and the next three ports, over TCP and UDP; most setups use 30000 as the game port. The Telnet port, 30004 by default, is for local administration and should never be opened to the internet. ### How do I set the player limit and password? In the ServerConfig section of dedicated.yaml: Srv\_MaxPlayers for the limit, Srv\_Password for a private server and Srv\_Public to choose whether it appears in the server list. ### Can I run a Workshop scenario like Reforged Eden? Yes. Copy the scenario into the server’s scenarios folder under a simple folder name and set that name as CustomScenario in dedicated.yaml. For large scenarios, Eleon recommends SharedDataURL, a link to a zip of the scenario’s shared data that players download. ### What are playfield servers? Every planet or space sector with players on it runs as its own process, EmpyrionPlayfieldServer. That is why memory grows when players spread out. Srv\_ReservePlayfields keeps spare processes ready for the next warp. ### How do I add admins? With the Empyrion Admin Helper (EAH), which comes with the dedicated server. Eleon’s guide says to use it while the server is stopped. ### How do I enable the Dark Faction DLC? Set EnableDLC to true in dedicated.yaml. It is needed for the Dark Faction scenario and other DLC content. ### Can I turn Easy Anti-Cheat off? Yes. EACActive in dedicated.yaml switches EAC on or off. Keep it on for public servers; EAC only works when the server runs on Windows. ### Does the server run on Linux? Not officially. Eleon supports the dedicated server on Windows; some players run it on Linux, but EAC does not work there. ### Can I play the experimental version? Yes. The server has an experimental branch, which in October 2026 carries version 1.20 while 1.19 is the public release. Players must use the same branch as the server. ### Where are the saves? In the SaveDirectory set in dedicated.yaml, in a folder named after GameName. Give every game its own GameName so saves do not overwrite each other. ## Ready to claim your galaxy?
