Atom Traffic Cars 3D is a three-dimensional arcade racer set in space. The player controls a futuristic ship moving across three traffic lanes. The goal is to avoid collisions with enemy ships and collect atoms. You must travel a distance of ten thousand light years. Collected atoms can be used to unlock new ship models in the hangar. The game ends either with the ship's destruction or successful mission completion. The pace constantly increases due to the growing game speed.
