Creating an Abiotic Factor server at RespawnHost
This guide takes you from ordering to your first join on your own Abiotic Factor server — including every launch parameter the server understands. At RespawnHost the server is installed and ready in under 90 seconds.
The tech behind it
The Abiotic Factor dedicated server is a separate server tool on Steam (app ID 2857200), downloadable anonymously via SteamCMD — you don’t need the game itself (app ID 427410) on the server. The server binary is AbioticFactorServer-Win64-Shipping.exe; Windows is the officially supported platform. The developers maintain the official server docs on GitHub (DFJacob/AbioticFactorDedicatedServer).
At RespawnHost all of this comes preinstalled — you only configure via the panel.
Step 1: Order the server
- Open the Abiotic Factor order page.
- Pick fixed package (flat monthly price) or Pay-Per-Use (per second, only while the server runs).
- Pick a package (from 2 GB RAM) and a location (Germany/Frankfurt or USA/Salt Lake City), then complete the order.
Step 2: Understand the launch parameters
The server is configured entirely via launch parameters — managed as startup variables in the panel:
| Parameter | Meaning |
|---|---|
-PORT=7777 | Game port (UDP) |
-QueryPort=27015 | Steam query port (UDP) |
-MaxServerPlayers= | 1–24; officially recommended is 6, the server warns above that |
-SteamServerName= | Name in the server list |
-ServerPassword= | Join password |
-AdminPassword= | Password for admin rights (see the admin guide) |
-WorldSaveName= | Name of the world folder (default “Cascade”) |
-SandboxIniPath= | Alternative path to SandboxSettings.ini |
-AdminIniPath= | Alternative path to Admin.ini |
-PlatformLimited=PC|Playstation|Xbox | Restrict crossplay to specific platforms |
-LANOnly | LAN only (port 14001) |
-MultiHome= | Bind to a specific IP |
Additionally recommended: -log -newconsole -useperfthreads -NoAsyncLoadingThread.
Warning
Never use -NOSTEAM — the server won't be reachable via Steam.
Step 3: Ports
Abiotic Factor uses two UDP ports:
| Port | Purpose |
|---|---|
| 7777 | Game port |
| 27015 | Steam query port |
At RespawnHost both are already set up — port forwarding is only a topic when self-hosting.
Step 4: Start and connect
- Start the server in the panel.
- In game: open Multiplayer → server browser and search for your
-SteamServerName— or connect directly via IP (IP:port from the panel). - Enter the
-ServerPasswordif set — done.
Frequently asked questions
How many players fit on an Abiotic Factor server?
-MaxServerPlayers= accepts 1–24. The game is officially designed for 6 players — the server warns above that, and balancing plus performance aren’t built for more.
Does the server run on Linux?
The officially supported binary is the Windows one (AbioticFactorServer-Win64-Shipping.exe). At RespawnHost you don’t need to worry about the operating system.
Where do I configure game rules like loot or hunger? Not via launch parameters, but through the world’s SandboxSettings.ini — fully explained in the sandbox guide.
Can PS5 and Xbox players join?
Yes, since 1.0 crossplay works on dedicated servers too. With -PlatformLimited= you can restrict it if desired — details in the savegame & crossplay guide.
