Great app if you love to watch ads. Technically, you don't need to watch any - but you won't get far if you don't. Good graphics when building tanks, lousy action when in the campaigns. No strategy involved, just roll along and wait until you get killed. Prices for building a tank are totally unrealistic - it costs more to build the Tiger than has ever been made by all of humanity. Download this if you're out-of-your-mind bored and love to watch the same ads over and over.
