In Real Construction Simulator 3D, you will have to operate heavy construction machines such as excavator simulators, dozer, dumper truck, heavy snow excavator, heavy crane, crane excavator, forklift, and other heavy construction vehicles. You will have to do this in order to build houses and other buildings. The game is based in the city, where you will have to build houses and other buildings, as well as a security wall around the city. The main task is to construct the wall in such a way that it will be strong enough to prevent intruders. You will also have to do this in time so that the president of the United Nations will not send the task to another builder.
