Valiant Hearts is Ubisoft's action/puzzle game set during World War I, and the latest dev diary puts the spotlight on the setting, characters, and a dog.

In the video below, the team members discuss the comic book-inspired visuals (which run on the Ubi Art framework, like Rayman Legends and Child of Light). They also talk about trying to make an emotional impact on the player, and how the different playable characters' stories tie together.

In addition, Ubisoft also released a couple of new screens, which you can see in the gallery below.

Valiant Hearts: The Great War releases on June 25 on PlayStation 4, Xbox One, PlayStation 3, Xbox 360, and PC.
