GoCrazyTank app for iPhone and iPad
Go! Crazy Tank is a simple game for your leisure times.
Make the tank move straight forward and fire by tap the screen or leave it spinning at a certain speed. Try to fire as much enemy cars as you can and avoid to crash into them.
May be one tank is too simple to you, a double tank option is here too! But be careful, your bullet may kill your friend tank as well.
Simple and fun.
