Special AP darts inflict more damage to MOAB-Class Bloons.
~ BTD6

Armor Piercing Darts is the fourth upgrade in the 3rd Path for the Monkey Sub in BTD6. It increases the amount of overall damage to MOAB-class bloons, mostly through the main dart but also through its Airburst Dart attack too. The main homing darts fired by the Monkey Sub to deal +1 damage to all bloons as well as deal another +2 bonus damage to MOAB-Class Bloons. Its Airburst Darts will deal only +1 damage to MOAB-class bloons, but together the main dart and the Airburst Darts can cause up to 10 damage to MOAB-class bloons per shot.

It costs $2550 on Easy, $3,000 on Medium, $3240 on Hard and $3600 on Impoppable.


  • When combined with other Armor Piercing Darts Subs and a Sub Commander, it becomes a massive Anti-MOAB force, even in later stages of the game.
