Cool game! It's amazingly easy to play. The entire game control consists of 2 buttons, and some touch screen control to select levels and stuff. It's like putting a classic arcade game to a different dimension. I love that I get to play it in my own home, watching them hover around the TV as my sister watches it. Plus, it's 360 degrees, so it's really immersive. Story line's also cool. Sometimes the director curses about the aliens. It is true, however, that the levels get harder and harder. The swarms of aliens get bigger and bigger, and it gets to be hard to take care of all the aliens at once.
