Bloons Tower Defense 5 - Hard Mode (Death Valley / Track 15)

You will need Dart Training Facility for this to work, set Glue Gunner to aim Strong. If you don't like Ground Zero (Ace 2-4) you can go for Artic Wind (Ice Tower 3-2) instead. I personally prefer Ground Zero because when things get tough you can just blow up the whole map. Enjoy!!!
