Zombie Nation

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.

The head of the samurai Namakubi hears of Shura falling into Darc Seed's clutches. He then heads to the United States to destroy Darc Seed, free the American people from the looming zombification and reclaim the samurai sword Shura.

Résumé

1999. What appeared to be a harmless meteorite crashing in the Nevada desert has turned out to be Darc Seed, an evil alien creature with horrible powers. By shooting strange magnetic rays, Darc Seed had turned the helpless nation into zombies and had brought the Statue of Liberty to life to do his dirty work. These rays had also given him control over many deadly weapons, but none were more powerful than the legendary samurai sword, Shura. When the great head of the samurai, Namakubi, heard that the sword had fallen into evil hands, he set off immediately for the United States. For only he possessed the strength and knowledge needed to recapture the magical sword and free the U.S. from the evil clutches of Darc Seed.
