About the game
You build your own vehicles from blocks and take them out into a world that is generated as you go. A vehicle can be a car, a tank, a plane or a mining machine. You gather resources, take on missions for mining corporations and unlock better parts as your standing with them grows.
Co-op comes in two forms, and both take up to four players online. In Co-op Creative you build and test together with unlimited blocks. In Co-op Campaign the group plays the missions together, shares one block inventory and one mission log, and can change each other's vehicles.
It is a toolbox more than a story. It suits groups who like building and testing odd machines. The console versions are cut down in places compared with PC.
