Bloons TD 5

MOAB Madness is one of the special missions in Bloons TD 5.
Your mission is to survive a wave of 50 MOABs with the given $50,000.

This might sound difficult at first but there is a really easy way to do this.
You will need to level up your Monkey Ace tower so that you unlock the Ground Zero ability before attempting this.

What you want to do is place two Monkey Ace towers on the map and upgrade both of them with Pineapple Present, Spy Plane, Operation: Dart Storm and finally Ground Zero.

Start the wave and wait for as many MOABs to be on screen as possible and then hit on your controller to activate Ground Zero ability. It will wipe most of the MOABs from the screen. Now you don't need to worry about the cooldown because you placed two of the Monkey Ace towers so you have 2 uses for the ability.

Wait for the rest of the MOABs to be on the screen and use the ability again and you are done!

Here is a video of me doing it:

If you have Super Monkey upgrades unlocked this one is easy. Put a Monkey Village in range of the first corner, then put one Super Monkey on the inside of the first corner, and another directly above. Upgrade both to Plasma and Robot (2 left path upgrades and 3 right path upgrades), and start the wave.
