This is a wonderful app I just came across, frankly it deserves a more 5 star ratings & reviews. Look for it at google play, hte name of the app is Joy Of Demolition 2. Try it, it's free.
If you are still not convinced then take a look at the trailer, find it at youtube, just type in Joy of Demolition 2.
Absolutely insane graphics for a free app.
You would have to be daft not to get this one.
