The plot of Zombie Nation takes place in 1999, when a meteor known as "Darc Seed" (Eva in the Japanese version) crashes in the Nevada desert. Darc Seed/Eva then shoots magnetic rays and turns the people of the United States into zombies. Darc Seed/Eva also brings the Statue of Liberty to life to follow its commands. The magnetic rays also allow Darc Seed/Eva to control many deadly weapons, including the most powerful weapon of all—the legendary samurai sword Shura.
