The story of crossed destinies and a broken love in a world torn apart. All of them will try to survive the horror of the trenches following their faithful canine companion. In Valiant Hearts: The Great War, the lives of all these characters are inextricably drawn together over the course of the game. Friendship, love, sacrifice, and tragedy befall each one as they help each other to retain their humanity against the horrors of war.

I use IOS Mavericks and works well. I strongly recommend this game.
