In the single-player game, G-Force scientists have cracked Godzilla`s genetic code from samples obtained during the Vortaak invasion. Scientists have refined the code to grow super-enriched "Godzilla-Matter" - a virtually indestructible substance with the exact physical properties as Godzilla`s radioactive back spikes. The Vortaak learn of the Godzilla Matter and strike Monster Island in an attempt to steal G-Cells and seize control of Earth`s monsters.
As Godzilla, the player awakens and fights to stop the UFOs from stealing G-Cells, and to free his fellow monsters from captivity. Throughout the game`s missions, Vorticia sends waves of monsters, UFOs, mind-controlled military and earth-threatening devices at Godzilla, who must fight to defeat the enemies and find the hidden G-Cells before the UFOs can steal them.
The epic battle for Earth will range across the globe in more than a dozen massive, destructible city environments, including San Francisco, Los Angeles, Tokyo, Osaka and New York. Environments have been enhanced and enlarged, featuring hills, oceans, harbors and mountains. All structures in the game have advanced destruction mechanics, enabling them to be partially damaged or completely destroyed through multiple impacts. Striking larger buildings will produce dynamically generated gouges that expose the internal skeletal structure before they eventually crumble to the ground.
