Cargo Shipment: San Francisco returns with a bit unusual Tower Defense style. Trucks, lorries and other vehicles will go around you and you have to load them.
Each depot can load more or less quickly or efficient. It’s up to you, their position or upgrades. The same thing happens to the cars. Each can be faster, slower, bigger so you should use some bonus items and things to slow them down or improve the efficiency of your guys. There are many levels but you have to make money to unlock them.
