Roll your game back to 1.1

Satisfactory Update 1.2 just dropped, but the mod loader (SML) and our mods aren't ready for it yet. The server is staying on the last 1.1 build (v1.1.2.2) so we can keep playing modded. To join, your PC copy needs to be on 1.1.2.2 too. Follow the steps below — take your time, it's not hard.
  1. 1

    Stop Steam from auto-updating the game

    In Steam, right-click Satisfactory → Properties → Updates and set "Only update this game when I launch it."

  2. 2

    Open the Steam console

    Press Win + R, type steam://open/console, and press Enter. A new CONSOLE tab appears in Steam — click it.

  3. 3

    Download the 1.1.2.2 files

    Paste this into the console and press Enter. It downloads about 12 GB — there's no progress bar, so just wait. If it errors out, run it again.

    download_depot 526870 526871 1858885725837604498

    When it finishes it prints a path like ...\Steam\steamapps\content\app_526870\depot_526871\ — that folder is where your downloaded files landed.

  4. 4

    Back up your current install

    Right-click the game → Manage → Browse local files to find your install folder, then make a copy of it somewhere safe — just in case something goes sideways.

  5. 5

    Clear out the install folder

    In your Satisfactory install folder, delete everything except these (leave them exactly as they are):

    • Manifest_DebugFiles_Win64.txt
    • Manifest_NonUFSFiles_Win64.txt
    • Manifest_UFSFiles_Win64.txt
    • the FactoryGame\Configs\ folder
    • the FactoryGame\Mods\ folder
  6. 6

    Copy the 1.1 files in

    Copy everything from the downloaded depot_526871\ folder into your install folder. If Windows asks about overwriting, choose to KEEP the existing files — do not overwrite those three Manifest_*.txt files. Keeping them is what stops Steam from re-updating you to 1.2.

  7. 7

    Install the mod loader for 1.1

    Grab the SML-only profile below, then in Satisfactory Mod Manager (SMM) import it and select it. Let it install SML for 1.1.

  8. 8

    Launch and connect

    Start the game (through Steam or SMM), open Server Manager, and connect to:

    factory.purplehax.com:7777

Before you start

You need to own Satisfactory on Steam (Windows). We're not handing out game files — you download them straight from your own Steam account. The big number in the command is just a public Steam reference (a manifest ID), not a copy of the game.

Important

  • Do not click "Verify integrity of game files" in Steam — that undoes all this and re-downloads 1.2. (It's also exactly how you go back to 1.2 on purpose later.)
  • Once SML and the mods are updated for 1.2, we'll all move back to 1.2 and none of this will be needed anymore.
