Advance Wars: Days of Ruin

Advance Wars: Days of Ruin (titled Advance Wars: Dark Conflict in Europe and Australia) is a turn-based strategy video game for the Nintendo DS handheld game console. It is the fourth and latest installment in the series and was released in North America on January 21, 2008; in Europe on January 25, 2008; and in Australia on February 21, 2008. It was planned for release in Japan as Famicom Wars DS: The Lost Light (ファミコンウォーズDS 失われた光) but this version was cancelled after several delays. The game is preceded by Advance Wars: Dual Strike, Advance Wars 2: Black Hole Rising, and Advance Wars.

Advance Wars: Days of Ruin was intended to have a darker atmosphere and more serious tone in contrast to the previous installments in the series, and features a new storyline independent of the previous games. Set amidst a post-apocalyptic world, the story focuses on the Rubinelle 12th Battalion, one of the surviving remnants of the military of the country of Rubinelle, which had been locked in a century-long war with its rival, Lazuria, prior to a devastating global meteor shower. In the aftermath, the Battalion devotes itself to saving any other survivors of the disaster, despite the shattered nations renewing their war against each other and an uncurable disease ravaging both sides. Meanwhile, a mysterious faction with unknown motives takes advantage of the destruction and pushes both sides deeper into conflict from behind the scenes.

A terrible asteroid strike has left the planet devastated. Few survivors remain and the world is in chaos. Toxic clouds are choking out the food supply. New diseases strike without warning. Terror runs rampant as people do whatever necessary for their own survival.

One small band fights to restore human dignity in a world gone mad...but the mission seems impossible. Their own country is being led by madmen. Their former enemy thinks only of revenge. Worse, behind the scenes works a mad scientist with unbelievable power, dreaming of eliminating the human race once and for all.
