Desert Challenge

Desert Challenge is a Nearly Impossible Track in BTD6. (Available in Co-op Mode, and Unlocked at Rank 92)

Overview
hot, dry, cliffy terrain. Located in the desert. There are four cliffs with four paths (one each cliff). As you notice below the track picture, there are two colored red S and E and two colored blue S and E. This means that the bloons will travel first on the red ones. After you've finish a single round, They will travel to the blue ones next to red, vice versa.

Even though the track has a lot of spaces to build towers and agents, it's still a Nearly Impossible Track because the paths are separated and the bloons change paths every round.

You can still beat this track through your hard work and skills. Just think of a plan to finish the track. When you had finished the track, you can earn a lot of Monkey Money and Awesome Points!

In Co-op Mode, Your ally have two different paths. You too, have two different paths.
