Ubisoft has released the first developer diary for their upcoming adventure game, Valiant Hearts: The Great War.

Featured above, you can feast your eyes on the dev diary that is focused solely on the art and the emotions they hope to ignite within you during the game. The story within Valiant Hearts is set within the tragedies of World War I, and it’s centered around a small group of unlikely allies who are just trying to survive.

One of the greatest challenges of the game is the very fact that the entire game is based on the first World War, and that most games simply opt for the second World War. In order to give the story more emotional impact, fictional characters with backstories inspired by real occurrences were created.

Valiant Hearts: The Great War is coming out on PC, PlayStation 3, PlayStation 4, Xbox 360 and Xbox One on June 25th.
