A group of 50 ft tall Kuiju Monsters have suddenly emerged from the depths of the sea and began attacking major cities around the world. In response, the USA Air Force quickly dispatches a team of its most advanced combat mechs to confront the threat. The mechs are 50 feet tall and heavily armed, making them a formidable force against the gargantuan sea creatures. The ensuing battle is a spectacle to behold, as the mechs unleash a barrage of projectiles and energy weapons at the Kuiju Monsters, all while trying to protect innocent civilians caught in the middle.
