Downstream (BTD5)/Strategies


 * Use Tack Sprayers placed in the top island for early rounds.
 * Placing an Arctic Wind on each of the three islands can slow down bloons for almost the entire length of the track.
 * Placing 3-4 Dart Monkeys on the first island will help for the first levels.
 * Do not rely on Spike Factories unless you are in Reverse Mode, because there are 4 exits to cover.
