Bus Simulator 18 features a sizable map of fictional modern city Seaside Valley, consisting of twelve districts, which is 2.5 times bigger than Bus Simulator 16.[2] The game allows players to drive eight licensed vehicles from four different bus manufacturers including Iveco, MAN, Mercedes-Benz, and Setra ranging from low-floor buses to articulated buses.[3] Like its predecessor, the game also uses a procedural generation system that requires players to complete different missions to unlock new districts. Management-wise, players are able to create their own bus lines, as well as buying, selling and upgrading buses.[4]
