In the year 2199, unrelenting attacks from the planet Gamilus have forced all life on Earth into underground dwellings and raised radiation levels to near-toxic levels. The only way to clean up all this harmful radiation is by using the Cosmo Cleaner, which the Queen of the planet Iscandar has generously offered to humanity. Unfortunately, Iscandar is 148,000 light years away, but Earth only has one year before rising radiation levels make it uninhabitable! The only vessel capable of making the journey is the Yamato - a spaceship equipped with advanced technology and modeled after the famous WWII battleship. Can the crew of the Yamato make it to Iscandar and back before the extinction of all life on Earth?
At first this might seem like an odd match, being that Dairugger is a straight Mecha title, but they share a great deal in common.
Much like Yamato, Dairugger has a ton of ship to ship combat.
Both have earth forces both in the 22nd century fighting aliens out to take your species out. And like many good alien forces, they have a g in thier name. One is Galviston, and the other Gamilos. There is also the need to go to the alien homeworlds to resolve the issue.
