Omega Land

Omega Land is where Advance Wars: Dual Strike takes place. It is unclear where each territory is set, though it is believed to have Orange Star in the middle, Blue Moon in the Southeast, Green Earth in the Mideast, Yellow Comet in the Northeast, and Black Hole to the west.

Although the Black Crystals are turning Omega Land into a desert, it is possible that there were already existing deserts, such as the Red Rock Desert, which would likely become a wasteland.

In Advance Wars: Dual Strike, Omega Land is once again invaded by the "Black Hole" army, which is led by a new and mysterious CO. Omega Land has thoroughly regenerated since the Macro land wars, which took place not long before. It is revealed that Black Hole is draining energy out of the Earth to create and heal new units using a device called "The Black Obelisk". Upon completing the campaign, the Black Obelisk is destroyed and Omega land ceases to decline.
