This second OMSI 2 download pack is all about utility vehicles in OMSI 2. The Download Pack Vol. 2 contains a total of nine different utility AI vehicles awaiting deployment on a diverse selection of OMSI maps, ranging from refuse collection trucks to multifunctional light trucks. Each boasts different repaints, and some also have their own animations (flashing warning lights or rotating brushes) and their own special sounds. The utility vehicles are not directly drivable, but they make the traffic on each map much more realistic.
With the OMSI 2 Download Pack Vol. 2 AI vehicles, modern maps look even more realistic and virtual driving comes another step closer to driving in real traffic conditions.
