Play the role of a mad scientist and breed giant monsters to destroy cities around the world. To attack a city, choose one of the available destinations in the map room. Your task in each city is to make sure that no building is left standing by activating your monster's abilities. You can earn additional cash by earning medals and collecting the skulls of dead humans. This cash can be used in the research lab to unlock new parts for your monster. You can change your monster's parts by accessing the workshop.
