Senjo no Valkyria Duel

Valkyria Chronicles D, also known as 戦場のヴァルキュリアドユーエル, or Senjou no Valkyria DUEL, is a mobile game released only in Japan. It was a free browser-based/iOS game, with radically different gameplay, focusing more on character management of war troops similar to sports team management simulations. It was released on July 26, 2012 and shut down on April 22, 2015.

The characters within this game feature many of the characters from the series of Valkyria Chronicles games, as well as the inclusion of new and exclusive in-game characters from its spin-offs.
