Kaiju Wars is a 2D turn-based strategy game developed by Foolish Mortals Games. The game is set in Floatio city, where the player assumes the role of the mayor in charge of defending the city against the attack of five different types of kaiju. The game consists of a campaign mode and a local versus mode for two players. In campaign mode, players progress through the globe-trotting fight against kaiju, playing tactical puzzles, commanding dozens of units in large-scale scenarios, and fending off repeated attacks while developing the city economically in city defense missions.

Kaiju Wars offers a variety of features, such as deploying tanks and jets to slow down the kaiju, building sacrificial army bases and airfields to distract them, and deploying experimental weapons like freeze rays and transforming mechas to keep them at bay. Players must also be prepared to evacuate the laboratory using transport trucks, boats, or planes when the kaiju get too close. The game also features Twitch integration, custom maps, and weekly challenges. Overall, Kaiju Wars is a fun and challenging game that will put players' strategic skills to the test.
