Space Battle Ship Yamato Uchu Senkan

Uchū Senkan Yamato on the WonderSwan Color is an adaptation of the anime series of the same name, also known as Space Battleship Yamato and Star Blazers.

It adapts the story of the original 1974 television series: in 2199, the Earth lies under siege by aliens from Gamila. The surface of the planet has become uninhabitable through bombardment by radioactive meteorites, so the surviving humans live underground. Hope arrives with a message from the planet Iscandar. If humans can somehow travel to Iscandar, they might acquire a device that can cleanse the planet of the radioactive damage. So from the husk of the Japanese WWII battleship Yamato, a powerful new spaceship is built that can fight through the Gamilan blockade and reach Iscandar. Time is of the essence, though: within a year, the built-up radiation will have killed everyone on Earth.
