Downstream (BTD6)

Downstream is an Intermediate track introduced in the Version 4.0 update on 12th September 2018.

Description
The track consists of a river alongside a looped stone path crossing said river a number of times. Bloons start from the top, loop around twice, and then exit towards the right of the screen, following the stone path.

Two rock piles can be removed for $350 each. They do not block Line of Sight limits, but they do prevent towers from placing on until they are removed.

Strategies
TBA

Trivia

 * This is the first track in BTD6 not to feature a new Hero.
 * This track is the first track to be named after an already existing track name without being related to the original track at all.
