Force vs Force

"Juggernaut does +2 damage per shot to MOAB-Class Bloons"

- In-game description

Force vs Force is an upgrade in the Primary Monkey Knowledge tree introduced in the initial version of Bloons TD 6. When Force vs Force is activated, Juggernaut's projectiles and Ultra-Juggernaut's sub-projectiles deal a bonus +2 damage to MOAB-Class Bloons. To unlock Force vs Force, the player must have 5 Monkey Knowledge points invested in the Primary Monkey Knowledge tree, and the 'Crossbow Reach' MK unlocked.

Summary
Force vs Force enables Juggernaut and Ultra-Juggernaut to be more reliable against MOAB-Class Bloons, as they both specialize in Ceramic popping power than MOAB-Class Bloon popping power, which makes them very bad choices for late game. Ultra-Juggernaut's main attack doesn't have any bonus damage, but the projectiles spawned by the main attack do have the bonus damage.

Tips

 * On maps like Moon Landing, the constant bouncing in the crater or other good Juggernaut spots can quickly pop MOAB-Class Bloons in the earlier rounds.
 * This is even better with Ultra-Juggernaut, because of the amount of Juggernaut balls the main attack produces, which do have +2 MOAB damage.
 * This MK is not necessary to unlock if the player wants to get to the better Monkey Knowledge (More Cash, Bonus Monkey!, etc.), as no Monkey Knowledge requires Force vs Force as of Version 30.0.
