Astral Breaker, an action-puzzle game similar to Tetris, has just gone free for a limited time. The game usual costs $1.99 and features both a single player and multi-player mode. The game may already be in your library as it went free for a few days in early July. But if not, then go grab it before the sale ends. Remember, you don’t need to fire up your Fire TV to purchase apps. You can purchase them from the Amazon website and select “Cloud Only” as your device. This way you can get in on a deal and install the app later at your convenience.
