Freezing (Tower)

The Freezing (also called Freeze) towers slow down the enemies in their range. They can be bought at the Global Upgrades screen for 250 Green Papers.

Appearance
It is a blue circle with a hole in the middle. In that hole is a rotating vent with a slightly lighter shade of blue.

Strategy
These are excellent support towers. As they level up, they increase the length of the Tesla's chain lightning and increase the duration of the Venom's poison. They can slow down the quick speed of the Fast and Jet enemies and can slow the Armored and Strong enemies' speed to a snail's pace. They can't slow down Icy or Bonus enemies, however, and their slow is reduced against Fighters. Upgrade their Freezing Percentage and Range first, then either Freeze time (how quickly freeze takes effect) or Defrost time (delay for freeze to wear off upon leaving the tower's range) depending on what you're having trouble with (Freeze time if you're encountering lots of Fast enemies, and Defrost if you need to "fill the gap" between this Freeze and the next).

The slowing effect of multiple Freeze towers does not stack; however, the freeze time will.
