In this detailed guide, we will explain exactly what version 1.39 includes, how to perform a safe and legal American Truck Simulator 139 download full, the differences between legitimate and pirated copies, and why updating to this version might (or might not) be the right choice for you.

Method 1: Steam (The Official Method)

American Truck Simulator is a Steam-native game. Valve’s platform allows you to roll back to any previous version using the "Betas" tab. Here is how to get version 1.39 legally: American Truck Simulator 139 Download Full: The Ultimate

Step-by-step guide:

Own the base game: Purchase American Truck Simulator on Steam (it frequently goes on sale for $4.99).
Open Steam Library: Right-click on "American Truck Simulator" in your game list.
Select Properties: Go to the "BETAS" tab.
Choose the beta: In the dropdown menu, select "temporary_1_39 - 1.39 for Legacy Mods".
Steam will download: Steam will automatically revert your game files to version 1.39. This is a "full" download of the 1.39 build.
Block automatic updates (optional): To prevent Steam from updating back to 1.40+, set the game to "Only update this game when I launch it" and always launch via the .exe file directly.

Does this include DLC?
The base 1.39 download includes the core game. To get the "full" experience, you must own the DLCs separately. However, Steam often sells "bundles" that include Oregon, Washington, Utah, and Idaho. You can purchase these, then revert to 1.39. The game will recognize your paid DLC even on the older version. Method 1: Steam (The Official Method) American Truck

Option 3: "Full Download" Repacks (HIGH RISK ⚠️)

You will see sites offering "ATS v1.39 full cracked + Colorado torrent." While these exist, we strongly advise against them. Risks include:

Malware: Crypto miners and ransomware hidden in cracks.
Corrupted saves: Pirated versions often desync and destroy 100-hour profiles.
No mod support: Workshop mods will not work with cracked EXEs.
No Convoy multiplayer.

Verdict: Use the Steam Beta method. It costs nothing extra if you own the game, and it guarantees integrity.

Fix: Delete the file immediately. Run Windows Defender Offline scan. Then buy the base game on a Steam sale (usually $5) and use the legitimate Beta branch.

4. Save File Format Changes

From a technical standpoint, 1.39 introduced changes to the save file format. This is often a point of friction for players managing mods or trying to load older saves into a newer game version. Version 1.39 necessitated that modders update their mods to be compatible with the new data structures, weeding out many abandoned mods in the process.
