Valiant Hearts: The Great War is inspired by letters from the First World War and a number of other historical materials. A fictitious story, the game is nevertheless based on real historical events and sites, such as famous battles like the Battle of the Marne or the Battle of the Somme on the Western Front.

An amazing collection of World War I memorabilia collected by members of the game's production team, such as correspondence sent to the front, medals, and others objects, have also served as important sources of inspiration.

Some team members even have direct family connections to WWI soldiers.
