You've often heard it said that "music saves lives". Well, in this new Android game, they do mean that literally, or at least, digitally. BeatDefense is a fusion of a missile arcade game and Dance Revolution, but this time for your fingers. You need to defend your city by getting rid of all the missiles that want to eradicate everything, all with the power of rhythm. But don't worry, you're not supposed to dance your way out of trouble. You just go with the beat.
