How to play ATS 1.56 on Steam
If your mods don't work on the latest version yet, SCS Software keeps previous game versions on Steam so you can keep using them. No password needed.
- In your Steam Library, right-click American Truck Simulator and open Properties.
- Open the Betas tab and pick
temporary_1_56from the drop-down (it shows as “1.56.x for incompatible mods”). If you can't see it, restart Steam. - Wait for Steam to download that version and open the game.
Before switching versions
- Back up your profiles (the
Documents/American Truck Simulator/profilesfolder, orsteam_profilesif you use Steam Cloud): a save made on a newer version may not load on an older one. - Steam Workshop mods always download in their latest version. They'll only work on 1.56 if their author includes a package for that version; if not, download the older file by hand from the official source listed on each mod page.
- DLC released after 1.56 may not work on that version.
- This option only exists in the Steam version of the game.
