Advance Wars: Dual Strike

On the heels of its last defeat, the nefarious Black Hole Army has fallen under the control of a deadly new commanding officer. He has sent its new COs to attack the nations of Wars World once again, and it’s up to the allied armies of Orange Star, Blue Moon, Yellow Comet and Green Earth to put an end to Black Hole once and for all.

Advance Wars: Dual Strike is the third installment in the Advance Wars series (first on DS media). Advance Wars is the international title of the Wars video game series, which dates back to the Family Computer game Famicom Wars in 1988.
The storyline is a continuation of the previous series and is set in the new location of Omega Land. Black Hole has returned under the leadership of a new commander who seeks to give himself eternal life by draining the energy of Omega Land. The Allied Nations struggle to overcome this threat and are eventually joined by several former Black Hole commanding officers in an effort to save the land.
