Multiplayer
In a first for the series, Days of Ruin includes online multiplayer over Nintendo's Wi-Fi Connection service, as well as a feature for players to share their own custom map designs and download maps made by others. Over 150 premade maps are included in the game for use in local multiplayer, and designed for two, three, and four-player matches. Multiplayer games can be played with only one DS game card: each player can pass the game to the next player when it is their turn.
