American Truck Simulator Update 1.3 going into Open Beta

The Open Beta of Update 1.3 for American Truck Simulator is available on Steam.

And yes, if you are keen to explore it even before the update is officially released for everybody,

the testing version contains the much anticipated Arizona DLC!


Here is out little marketing blurb for Arizona: Drive through the streets of 15 new cities including the largest city and capital,

Phoenix, and visit the distinctive southern centers Flagstaff and Tucson. Discover a section of the famous Route 66 with its key landmarks.

Cross the Colorado river over unique bridges and explore many wonderful vistas and famous landmarks within this region.


The Arizona State is not the only new feature of 1.3 update of course.

The list of changes and fixes is much longer, here is a recap of the key ones:

  • New accessories added to 579 a T680 (bullbars, deflectors, sideflares, etc).
  • Default air horn added to all trucks (attribute air_horn in sound accessory).
  • New engine sound of W900 (air intake).

You can find the beta in the public_beta branch on Steam.

(Steam client → LIBRARY → right click on American Truck Simulator → Properties → Betas tab → public_beta - 1.3 public beta).

A word of caution: make sure to back-up your profile and save game data before experimenting with beta builds!

Please keep in mind that this is still only a test version of the update,

it's perfectly ok for you to wait and stay away from it until it's stable and final.

If you are curious though and want to assist us in polishing it, we greatly appreciate your help.

Please report any bugs on our forum.

We added another portion of Highway 101, which leads from San Rafael to Eureka.

Highways surroundings is composed by typical redwood forest. We have also added new city of Ukiah hosting supermarket and farm depot.

Last but not least, yesterday we released the public beta version of SCS Workshop Uploader tool,

that is compatible with latest game updates. More details here
