3DBE is a game around engineering and constructing. Creating ingenious architecture and mechanics in a physicalized world by combining materials like beams, ropes, interactive hydraulics and street segments. Construct one of the endless possible constructions and make them move, maybe through a selfmade world or space created in the leveleditor. In a mission campaign you will have to drive a truck over the bridges just made before. Bridges in the meaning to connect one point to another. This could be a bow bridge over a river, a crane to lift the truck up a mountain, a cable car to bridge a canyon or whatever is possible to realise with a limited amount of credits. So its important to build wise to get stability, -otherwise you could see an impressive collapse of the construction. To make that possible, you get an easy of access and strong 3D editor.
robots are not really the main part of the game. I mean not of the campaign, you can do what you want, this just shows a bit of what you can do if you want.
