War of the Monsters is a 3D fighting game developed by Incognito Entertainment, released in 2003 for PlayStation 2 and later made available on PlayStation 4. Drawing inspiration from classic giant monster films, the game features ten distinct creatures battling across ten fully destructible urban environments. Combat takes place on a large scale, with players trading uppercuts, body slams, and character-specific special attacks while contending with active military opposition. The environments serve as arsenals in themselves — steel girders, radio antennae, building rubble, tanker trucks, and army tanks can all be grabbed, thrown, or used as improvised shields. Structures can be toppled onto opponents, and certain stages trigger large-scale environmental hazards such as tidal waves and earthquakes. The combination of interactive surroundings and roster variety gives the game a sandbox quality that sets it apart from conventional one-on-one fighters.
The plot is set in the 1950s where a fleet of alien flying saucer warships invade the Earth, causing massive damage. The scientists of the world's nations manage to create a series of secret weapons, which, when activated, let loose shock waves that short-circuit the saucers and cause them to crash. Unfortunately, each flying saucer is fueled by a green radioactive liquid, which leaks out from destroyed crafts as they crash. Through this, the fuel infects creatures, humans, and robots, creating a war between the monsters. The player acts as one of these monsters and battles against the rest in fictional cities across the globe and the remaining UFOs.
