Since February, wannabe truckers have been putting the pedal to the metal in convoys across the country in American Truck Simulator. Now developer SCS Software is putting the finishing touches on update 1.3 that includes the Arizona DLC.

The update, along with a bunch of tweaks and bug fixes, is going into open beta. Players will be able to test out the highways of Arizona, which will have 15 cites including Phoenix, Flagstaff, and Tuscon as well as the famous landmarks along Route 66.

The beta is available through Steam, but no official date for the DLC has been announced. If you like modding for the game, SCS released the SCS Workshop uploader tool yesterday.
