Many games were presented at E3 2014—some looking intense; some looking scary; some looking visually stunning; and some looking like a hell of a lot fun. But none looked quite as beautifully depressing as Valiant Hearts: The Great War.

The game is set during World War I, mixing exploration, action, and puzzles in a 2D adventure. It’s inspired by letters written during the Great War, and you’ll relive historical battles playing as four different characters joined by a faithful canine companion.

You can watch the trailer for Valiant Hearts below.
