With a different take on the tower defense genre, Amazon’s first foray into making games is fun, if you’re playing on a tablet and not a phone. The goal of the game is to fight back waves of enemies attempting to reach your base on a set path. But instead of building towers strategically in their path, your goal is to launch planes to fight them off. You control the aircraft’s flight path by drawing a line with your finger, which can cause the plane to switch directions when it hits a wall or you can draw a continuous circle to stay put. It’s a more hectic strategy experience than placing and upgrading turrets—a refreshing change for the tower defense genre. The biggest issue with Air Patriots is that the experience feels crammed when confined to a smaller screen, such as an iPhone or Android smartphone. With so much happening on the screen, this game seems better suited for a larger smartphone or tablet.
