Advance Wars: Days of Ruin, also known as Advance Wars: Dark Conflict in Europe, is a turn-based tactics video game developed by Intelligent Systems and published by Nintendo for the Nintendo DS in 2008. Set in a post-apocalyptic world, it represents a departure from the bright atmosphere of previous titles in the series.

It combines classic strategy gameplay with a darker, more serious narrative.
