Another (paid) DLC for the American Truck Simulator is now available for Linux on Steam: "Oklahoma".

From the grand American highways running through the hills of dusk-red rock to leading cities bustling with culture, landmarks, and businesses, Oklahoma is a diverse state shaped by its history and industries.

Located in the south of the country, "The Sooner State" generally tends to have a reputation of being a rather arid place, however, it’s much better to avoid judging this book by its cover. The state is home to wonderful state parks, several natural marvels, and historical places full of mysteries and legends. But those who are looking for something more practical instead will find their purpose as well since the local road network and a strong economy driven by natural gas and oil production will keep every trucker properly busy.
