Advance Wars

Advance Wars is a turn-based strategy video game developed for the Game Boy Advance by Intelligent Systems and published by Nintendo in 2001. It was released in the USA on September 10, 2001, but put on hold in Japan and Europe due to the following day's terrorist attacks in the USA. Although released in Europe in January 2002, neither GBA game was released in Japan until the Game Boy Wars Advance 1+2 compilation on November 25, 2004.

The story of the Advance Wars campaign begins with the nation of Orange Star in a war against the neighbouring country of Blue Moon. As a tactical adviser for Orange Star, the player follows the war effort through all four countries over the course of the game. In the end, it is revealed that the enigmatic Black Hole Army, under the command of Sturm, is the true enemy. Using a CO doppelganger clone of Andy, Sturm stirred up war among the four countries in order to confuse, weaken, and eventually conquer them. Once this is revealed, the four countries unite to drive Black Hole out of their land.
