The last hope of Earth, the Macross, begins to wage a lonely war; but what hopes can one ship have when facing against an entire alien race?
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 battleship Yamato - a rusty relic of World War II. Can the crew of the Yamato make it to Iscandar and back before the extinction of all life on Earth?
Both are old sci-fi space opera adventure type animes, and in both the protagonist are fighting aliens off from taking over and destroying the earth. If you liked one you will most likely like the other.

Kei must now journey to find a way to restore time and space, try to make his way home, and avoid being caught by the Chilam army.
Macross and Orguss share virtually the same key staff, from director, to character and mechanical designers, to composer, to writers, etc. And above all they have a similar vibe with some serious drama here and there tossed in with a little fun comedy at times, and you'd almost believe they're set in the same universe. All in all Orguss feels like it makes a better unofficial sequel to Macross than any of the official sequels Macross ever got.
