Nintendo's turn-based military strategy series continues with Advance Wars: Days of Ruin. As the ominous subtitle suggests, the game takes place on a ravaged Earth with civilization teetering on the brink of despair. Meteorites have all but wiped out modern-day conveniences and amenities, with the tattered remnants of two former superpowers vying for control. One vows to protect Earth's survivors, while the other intends on finishing them off. In addition to a bleaker setting filled with sepia toned cut-scenes, Days of Ruin offers four-player online support via Nintendo Wi-Fi Connection. Solo commanders can embark on a story-driven campaign spanning 26 missions, gradually unlocking additional training missions as well as map editor for custom scenarios.
