Godzilla: Save the Earth

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.
