Bloons TD 5

This achievement is fairly simple. You can find this mission in the main menu by going to challenges, then to special missions. There you will find the covert pops mission. I was rank 30 when attempting this.

Here is the video of my play through.




Start out by placing a spike factory towards the bottom of the map. This will be good enough to get you thru the first few waves. Then place a ninja monkey in the center. refer to my video on how I upgraded him. The most important part is the monkey apprentice with the monkey sense upgrade. This way you can take care of the lead balloons. Add a few more upgrades to the apprentice as you get the cash to do so.

As you earn more cash, add a few more ninja monkeys and upgrade the right side once, and the left side fully. Also upgrade the spike factory to drop spikes quicker in case some of the balloons happen to sneak by.

Sit back and enjoy your easy gs!

If you are having trouble following how I go about my upgrades, feel free to watch this guide where I breakdown my preferred tower upgrades.


Thanks and good luck!
