With better graphics, gameplay, sound, and controls, this is a great update to the classic Rescue Raiders game from the mid-80s. You wont be able to solve this game by just blasting everything in site - youll need strategy and a steady hand to protect your ground units and solve each mission. I love that you can control the game either via the accelerometer or the touch screen - choose the interface that you are better at. Well worth the price for the full version!
