Heat and Cold

Heat and Cold is another Gameplay Mechanic that has many effects. It is neutral, meaning that it doesn't only buffs/nerfs towers, but bloons too.

Many tracks have a default temperature setting, but you can't change it.

Warm
Mostly during Day, the track will be warm, it as no effect on towers nor on bloons. It is pretty much the BTD we all know.

Hot
Meanwhile, burning and hot tracks (Solar Core, Sunset Hill, etc.) will have some effects (WARNING: Heat Resistant Towers/Bloons are immune):

Towers

 * Lose 1 HP every 2.5 seconds.
 * Monkey Towers shoot 20% slower.
 * 9% Chance to instantly die every 4 seconds.
 * -50% Chance to evade attacks.

Bloons

 * Popped by 1 layer every 3.4 seconds (Burn effect).
 * Move 10% slower.
 * 14% Chance to be jammed.
 * Non-Boss Bloons have a 9% chance to instantly die every 4.3 seconds.

Cold
Some tracks will feature low temperature (The Rink, Monkey World, etc.). These are the Cold effects (WARNING: Cold Resistant Bloons/Towers are not affected):

Towers

 * 3% Chance to be frozen for 4 seconds. Refreshed each 4.65 seconds. Deals 2 HP damage.

Bloons

 * 3% Chance to be frozen for 3.5 seconds. Refreshed every 4.9 seconds. (That's a really low chance!)
