Hello everyone, sorry for the late upload, Youtube failed when I tried at first. Also, the end was cut off by my game crashing but nothing of note happens afterwards.
But with that aside, here's how to beat the Professor Evil Challenge in Bloons TD Battles:
(Note, use the eco boost whenever it is off-cooldown.)
1. Buy 2 3-0 dart monkeys set to last and work towards a 3-2 ninja.
2. Use the tower boost 18 seconds in.
3. Work towards getting a 2-2 Sniper in strong.
4. Use a tower boost for the camo zebras.
5. Enjoy your free 500 medallions!
I hope this guide has been helpful for you. If you have any other solutions, feel free to comment them (heck, they might be better than mine!).
And to wrap things up, PlEaSe ReMeMbEr To LiKe, SuBsCrIbE aNd CoMmEnT and have an economical day!
