Ubisoft announced that the console game Valiant Hearts: The Great War is coming to iOS devices on September 4, 2014. The game is a puzzle adventure title that follows a German soldier named Karl and his wife Emile in World War I. Emile must team up with Freddy, an American volunteer in the French army, and Anna, a Belgian student, to take down the German leader Baron Von Dorf.
The game was partly inspired by "letters and postcards of Félix Chazal, a French solider and great-grandfather to Yoan Fanise, a Valiant Hearts producer at Ubisoft Montpelier," according to Touch Arcade. The letters are featured in the game along with real-world facts about the Great War. Valiant Hearts is also powered by Ubisoft 's UbiArt Framework game engine.
