Combat of Giants: Dragons, known as Battle of Giants: Dragons in North America, is a video game in the Combat of Giants series developed by Ubisoft Quebec and published by Ubisoft for the Nintendo DS. It was released on September 29, 2009 in North America and on October 2, 2009 in Europe. In the game, an extensive war between dragons and humans caused the Lord of all the Dragons, Ninnurtu, to gather the noble Ebebu dragons and the foul Salmu dragons and combine their powers to create Tammabuku, their own world in which they could have peace. However, the Salmu dragons stole the gems of the Ebebu dragons which were the power source of all the dragons and Ninnurtu was left powerless from creating the world. The player, the last Ebebu dragons, has to win back all of the gems stolen by the Salmu dragons and continue Ninnurtu's legacy as the Lord of all the Dragons.
The gameplay is divided into two parts: Exploration and Gameplay. Exploration mode allows the Player to freely roam in an area to complete objectives, unlock certain areas, and fight Salmu dragons. When the Player gets too close to an opponent dragon, the Combat mode is triggered. Combat mode is a turn-based fight where the Player can either attack, block or dodge to gain Dirga necessary to use Special Attacks from the gems. Each copy of the game comes with a booster pack containing cards. There are "dragon" cards and "gem" cards. The dragons are based on the dragons that you fight within the game in terms of appearance and names. The gem cards have 15-character codes that can be entered into the game to acquire powerful Gold gems.
