Transformers: Earthspark - Expedition

Autobot Bumblebee, under the leadership of Optimus Prime, tries to stop the evil Mandroid, who is trying to destroy the Earth. The hero goes in search of ancient Cybertronian technologies scattered around the world so that the antagonist cannot take possession of them. In the game you can explore three open locations (mountains, desert and snowy valley) in the form of a Transformer or a car into which you can transform at any time.
