Ability now increases attack speed and pops by 100% for all Monkeys for 20 seconds.
~ BTD6

Homeland Defense is the final upgrade of Path 2 for the Monkey Village in BTD6. It allows the ability to increase attack speed and pops of ALL towers on screen by +100% for 20 seconds, as opposed to the local +50% attack speed and pierce bonus from the Call to Arms ability. The cooldown stays the same at 60 seconds. It costs $34,000 on Easy, $40,000 on Medium, $43,200 on Hard, and $48,000 on Impoppable.


  • To make the most of Homeland Defense, this upgrade is best used among large quantities of powerful towers that rely on high attack speed and high pierce boosts. Fortunately, the advantage comes from the fact that Homeland Defense ability affects globally to all towers on screen.


Homeland Defense is a very powerful support tower when there are a large number of powerful towers on screen. Like Call to Arms, it is best used in combination with towers that have relatively low pierce and/or attack speed but are more powerful in groups. Again, treat this upgrade as an upgraded emergency ability against potentially difficult rounds.

However, the Homeland Defense ability has only 1/3 uptime, as its ability lasts for only 20 seconds and the cooldown is 60 seconds. As such, this upgrade is usually only seen in late-game runs, but it is sometimes used in certain 2MPC runs.

  • This does NOT stack with Call to Arms. Instead, it overlaps any active Call to Arms, thereby cancelling them out until Homeland Defense ability expires or Homeland Defense is sold.
  • Homeland Defense's ability cannot be reactivated until it expires, unlike Call to Arms, where multiple can be activated at once.
  • Between Version 9.0 and 18.0, the old description was "Ability affects ALL Monkeys and for 20 seconds." but was since changed to clarify the boosted ability bonuses.
