Construction-Simulator 2015 turns construction work into a vehicle-focused simulation, placing players in control of machines from LIEBHERR, STILL and MAN. Jobs range from excavating a house foundation to pumping concrete into factory walls and positioning large roof trusses with a mobile crane. The world is freely navigable, with towns, fields and a highway providing a varied setting for the work.
The driving and operating model has a practical distinction: excavators can be steered with two joysticks using SAE controls, while players can switch between arcade and pro controls. A dynamic mission system connects jobs to a growing construction business, with success leading to larger contracts and additional office locations. The game also supports custom vehicles and construction sites through its Construction Kit, giving players a way to make and share their own content.
Construction-Simulator 2015 can be played alone or cooperatively. In multiplayer, up to four workers can tackle missions together, splitting tasks such as digging and hauling, or spend time in the open world. The host leads a shared construction company, and more experienced groups can work across several sites at once.
