Acorn Assault, a turn-based game with a match-3 combat system, has just dropped down to $0.99. This is the lowest price this game has ever been. Acorn Assault was specifically designed for the Fire TV and is not a port of a mobile app. This game has no ads or in-app purchases, so you’re getting the full uninterrupted experience. The game is compatible with all Fire TV and Fire TV Stick models, but does require a game controller to play.
