HQ Retro School Bus – it’s a very detailed 1970s school bus in two different versions – clean and abandoned rusty. Both models have a carefully crafted exterior and interior, animated arm-door, separated wheels, and steering wheel with the pivots correctly aligned. Also, this pack includes the rigged drivable version of the bus, so you can drive it in your level.
