Godzilla Unleashed

Plot
The storyline of Unleashed, taking place twenty years after Godzilla: Save the Earth, begins with a meteor shower raining down on Earth, causing climate shifts and earthquakes. Simultaneously, the kaiju of Earth begin to attack cities across the globe as a result of crystals growing on the ground. Factions form among the members of Earth as well as the monsters attacking them, totaling four monster factions. Choices within the story affect later events, including the relationships between Earth factions and the monster ones. The Vortaak, returning from the previous games, choose to invade and use the crystals to seize Earth, but their mothership is knocked into San Francisco bay. It is revealed in the finale that the source of the crystals is from SpaceGodzilla trying to escape the alternate dimension he was imprisoned in at the end of Save the Earth.
