Your ship in Battle Universe 2D will fly through outer space, which will be too cramped due to the large number of different cosmic bodies: meteorites, asteroids, and then alien ships will be added to them. All this is rushing towards your ship and you either have to dodge or destroy what is flying towards you. By pressing the mouse button you activate the cannon on board the ship so that it can defend itself. In the upper left corner you will find your standard of living and the number of accumulated coins. They can be collected and received as a trophy after destroying an alien ship in Battle Universe 2D.
