SCS Software said about the release:

From large cities to small humble villages in the countrysides, truckers will also be able to drive on roads which lead to scenic coastlines alongside the Black Sea. These regions also offer a large variety of industries for players to deliver to and from; including farms, logging companies and the mining industry.
