Valiant Hearts: The Great War, the critically acclaimed puzzle-adventure game, has just gone on sale for $0.69 when you factor in the Amazon Coin reward. This is the first time this game has dropped below its regular price of $4.99. It is on sale for $0.99 with a 30 coin reward. It has received great critic reviews across the board. The poor Amazon rating is a result of stability issues the game has on Fire tablets. I haven’t had a chance to play it so I don’t know if the issues extend to the Fire TV. Be warned that buying the game only unlocks the first of four chapter, with each additional chapter costing about $3 depending on the coin reward offered.
