In addition to the game itself, the iOS and Android versions of the game feature an interactive comic Valiant Hearts: Dogs of War.
Valiant Hearts follows five characters that are drawn together by one common cause: reunite a young German soldier with his lost love. Taking place between 1914 and 1918 during the outbreak of World War I, the characters must make their way across the war-torn battlefields. Each character can solve a different set of puzzles, such as Emile using a bone as a makeshift lever, and Freddie using wire-cutters to bypass dangerous obstacles.
The game's art style resembles a hand-drawn, comic book style. With exaggerated character designs to create contrast to the war-torn environments.

Walt - A doberman pinscher, who interacts with each of the characters during their adventures.
