How to Make an Abiotic Factor Server in 2026

How do you create a dedicated Abiotic Factor server, hosted or on your own PC? SteamCMD, ports, and RunServer config, step by step.

Published on 27 août 2026

Want your lab team to keep exploring the facility together on a persistent world, without one person always having to host? A dedicated Abiotic Factor server runs independently of any one player's game session. Here's how to set one up, both ways.

The two ways to create an Abiotic Factor server

Option 1: host with a provider

You rent an Abiotic Factor server from a specialised host. It runs 24/7, comes with a panel for files and backups, and includes DDoS protection. This is the simplest option for anything beyond a quick test — see our [Abiotic Factor server cost guide](/en/guides/abiotic-factor/abiotic-factor-server-cost) for real prices from €6.99/month.

Option 2: run the server on your PC

You install the dedicated server tool via SteamCMD and run it at home. Free on the software side, but your PC needs to stay on, you expose your home network, and you configure port forwarding and the RunServer script yourself.

Which option should you choose?

For anything beyond 1-2 players testing things out, go with a host. At under €7/month for the full 6-player cap, it removes the always-on requirement and the manual configuration entirely.

Creating an Abiotic Factor server with a host (recommended)

Choose your plan based on player count

Abiotic Factor caps at 6 players. For 1-3, an entry tier is enough. For the full 6, compare NitroServ's single €6.99/month plan against Minestrator's MyBox 8 (€13.99/month) in our [hosting comparison](/en/games/abiotic-factor).

Order and access the panel

After ordering, you receive panel access by email. Your server appears in Stopped status, ready to configure.

Set your server name, password and player cap

Most panels expose the key launch flags directly: server name, an optional password, and max players (up to 6).

Start the server and connect

Start it from the panel, then connect in-game via the server browser or direct IP if your host provides one.

Add yourself as an admin

Abiotic Factor manages admin rights through an Admin.ini file with your SteamID listed under [Moderators]. Check your host's panel for a shortcut to edit this, or access it via FTP.

Creating an Abiotic Factor server on your own PC

Install SteamCMD

Download SteamCMD and extract it to a folder, e.g. C:\steamcmd.

Download the dedicated server tool

Run: steamcmd +login anonymous +force_install_dir "C:\AbioticFactorServer" +app_update 2857200 validate +quit. The Abiotic Factor Dedicated Server Tool is Steam AppID 2857200.

Open your ports

Abiotic Factor uses UDP 7777 for game traffic and UDP 27015 for the Steam query port by default. Forward and allow both through your firewall.

Create a RunServer script

In (Server Install)/AbioticFactor/Binaries/Win64/, create a text file with launch flags, for example:

AbioticFactorServer-Win64-Shipping.exe -log -newconsole -useperfthreads -NoAsyncLoadingThread -MaxServerPlayers=6 -PORT=7777 -QueryPort=27015 -ServerPassword=YourPassword -AdminPassword=YourAdminPassword -SteamServerName="Your Server Name"

Add admins and launch

Add your SteamID to (Server Install)/AbioticFactor/Saved/SaveGames/Server/Admin.ini under [Moderators], then run the script. Keep the console window open — closing it or sleeping the PC ends the session for everyone.
