Monkey Fort

"The Fort increases the popping power of all nearby towers by 1."

- Official Description

 is the first upgrade on path 2 for the Monkey Village. It increases the pierce of each tower in its radius by 1. It is most effective on towers with low pierce, but its efficiency decreases the higher pierce tower has.



Effect
Monkey Fort will increase the pierce of all nearby towers by +1. This has the greatest proportional effect on fast-attacking and/or multi-projectile towers with low pierce, with the best examples being Super Monkeys and Tack Sprayers.

Affecting

 * Dart Monkey
 * Boomerang Thrower
 * Glue Gunner (its projectile can pierce bloon)
 * Bomb Shooter (Frags)
 * Ninja Monkeys (Flash Bomb)
 * Monkey Bucaneer (Grape Shot)
 * Monkey Apprentice
 * Dartling Gunner
 * Heli Pilot
 * Spike Factory (Added spike on each pile).
 * Monkey Engineer

Not Affecting

 * Ice Monkey (~Infinite pierce)
 * Tack Shooter's Ring of Fire.
 * Sniper Monkey
 * High Energy Beacon
 * Bloonchipper
 * Monkey Farmer Pro
 * Beekeeper
 * Monkey Engineer's Bloon Trap
 * Road items (with the exception of road spikes on Bloons TD 5 Mobile allowing them to pop 11 bloons instead of 10)
 * Banana Farm
 * Abilities of any tower or agent except the MOAB assassin ability missile

Summary
Monkey Fort increases pierce for all nearby towers. It has the best effect on towers with fast attack speed and/or shoot multiple projectiles per shot.

Tips

 * Even if the Monkey Fort is combined with a tower that cause effects in the impact like the Glue Splatter or the Bomb Tower, Mortar Tower, it still increases the popping power by 1. (In Glue Splatter's case, +1 splats) However, since those tower themselves already have very high popping power, they're buffed very little.
 * Monkey Fort turns a Super Monkey into half of a 1/0 Super Monkey that only shoots one projectile (even though it doesn't pop frozen bloons), making this upgrade worthwhile if the player's Super Monkey(s) are in radius of it.

Differences Between BTD5 Flash and BTD5 Mobile
Monkey Fort now duplicates explosive projectiles and several other types of projectiles. The following projectiles affected are: Glue Splatter, Cannon Ship bombs, Flash Bombs, Glaive Riccochet, Hydra Rocket Pods, Apprentice Fireballs, Spectre bombs, Apache Dartship rockets, and the MOAB Assassin ability missiles.

Trivia

 * This is the only upgrade for the Monkey Village that does not give it a radio tower.
 * The fort is missing on the BTD5 artwork when looking at the Towers section in the main menu. It appears as normal in-game.
 * If a Spike Factory is in a Monkey Fort's radius, it'll create spikes that pop one more bloon and appear with an extra spike.
 * In Version 4.3.1 in Bloons TD Battles Mobile, the Monkey Fort has been nerfed so that it no longer duplicates Glaives from Glaive Riccochet, and in version 4.9 it no longer duplicates Ninja's Flash Bombs, Buccaneer's Cannon Ship bombs, and Glue Gunner projectiles.
