DNA Track



The DNA Track is a Extreme Track unlocked in Rank 57. Why? Because it has the shortage of towers and the criss-crossing of the track. You could play this for 50 MM.

Overview
It shows a microscopic view of a DNA. 2 paths criss-cross each other. The red path starts above and ends below. The blue path starts below and ends above. Sometimes, bloons change paths and reverse it's pathway. That is what makes it so hard.

Tower Placement
You can only place tower at the colored germs.
