Arctic Wind

Arctic Wind is the final upgrade for the Ice Tower in BTD4. With this upgrade, bloons slow to about one third of their original speed due to the cold of Arctic Wind. Arctic Wind does not slow down MOAB's or BFB's but will slow Ceramic Bloons. This makes them near useless in later rounds as there are alot of bfbs and moabs and the snap freeze will only affect some of them.

Appearence
This is the only upgrade of the ice tower that changes its appearence. The ice tower gets bigger, but the middle stays the same. The outside is shaped like jagged rocks, just a little darker in color than the middle. The bigger appearence affects the range, so the range gets larger.

How to Use

 * 1) One of the good ways to use this tower is to use it against mobs of bloons. Even the bloons that can't be frozen will be slowed down to let the other towers do their work. So the Arctic Wind should be placed at the beginning of the tracks. In the late levels, even Arctic Wind can have a high pop count.

Trivia

 * Even through the Arctic Wind slows Camo Bloons, it can't attack them. (Unless there is a Monkey Beacon upgraded to Sonar Beacon and up in the area)
