Pierce

Popping Power, also called Pierce, is how many bloons a tower's projectiles can pierce through. 1 popping power=1 bloon pierced. Most towers have an upgrade that increases popping power. In addition, the Monkey Village's Monkey Fort upgrade increases most nearby towers' popping power by 1.

In BTD5 the Monkey Lab offers a popping power upgrade up to a total Popping Power increase of 20% for all towers. The way this appears to work is that each tower will have that percentage chance to fire a projectile with increased popping power. A 0/0 Dart Monkey will have a 20% chance to pierce 2 bloons instead of 1. A 0/2 Dart Monkey will have a 20% chance to pierce 8 bloons instead of 4.

In Bloons Monkey City, the amount of Popping Power can be influenced by Monkey Knowledge Packs. When a specific rank regarding "pierce" of a tower is unlocked, the Popping Power may increase by either an integer, a percentage, or by an "every X^th shot" (where "X" is an integer).
