Automatically triggers a powerful missile attack whenever MOAB-Class Bloon spawns from the Bloon entrance.
~ BTD6 description

Pre-Emptive Strike is the final upgrade for Path 2 for the Monkey Sub in Bloons Tower Defense 6. It automatically triggers a MOAB Assassin-esque effect whenever a MOAB-class bloon spawns from the entrance, dealing 750 damage to that blimp upon impact. In addition, its First Strike ability cooldown is reduced from 60 seconds to 45 seconds, and its Ballistic Missile attack deals 11 damage (from 6 damage) to Ceramics and MOAB-class per missile, shot every 0.5 seconds instead of every 1.5 seconds.

It costs $27,200 on Easy, $32,000 on Medium, $34,560 on Hard, $38,400 on Impoppable.

StrategyEdit

SummaryEdit

Following the 18.0 buff, Sub Commander combined with Pre-Emptive Strike is an acceptable combo on easier maps, destroying DDTs while providing damage on other bloons. Despite this, Pre-Emptive Strike still remains extremely costly while still requiring a lot of support for the children bloons created when it fires it's missiles, and not being strong against multiple ZOMG rounds as it cannot deal much damage to them. 

TipsEdit

  • Each missile deals 750 damage, enough to destroy the outer layer of a non-freeplay M.O.A.B, a D.D.T and a B.F.B. Note that it leaves the children unharmed.
    • Starting Round 83, normal BFBs are no longer instantly popped.
  • The triggered special missiles can be fired at an infinite fire rate, always shooting a missile at every M.O.A.B-Class Bloon that spawns from the entrance.
  • Note that the Pre-Emptive Strike missiles will not be able to fully pop Fortified DDTs and Fortified BFBs, since the Fortified DDTs on round 99 have 1,104 health each and Fortified BFBs have healths from 1,500 to 1,902 depending on the round.
  • Regardless of camo detection, Pre-Emptive Strike will still shoot triggered special missiles to DDTs that come from the entrance.
  • Although the Pre-Emptive Strike is extremely powerful at obliterating MOABs that spawn from the entrance, there may be a lot of Ceramics that spawn underneath. Ensure your defense can handle the Ceramics underneath, especially on Rounds 81+.
  • Pair with Sub Commander for far more effective Pre-Emptive Strike demolition. With the double damage to the passive ability, it can take out the Fortified DDTs on Round 99 with ease, assuming standard blimp health.

TriviaEdit

  • This upgrade is one of four x/5/x upgrades to keep the same ability as the preceding upgrade, the others being the Druid, Spike Factory and the Heli Pilot.
  • This upgrade is one of the few Tier 5 upgrades to have multiple appearances from crosspathing. It will have a second gun if there are any upgrades on the bottom path.
  • This, Carpet of Spikes, Bomb Blitz, Elite Defender, Legend of the Night and Commanche Defense are the only upgrades that have automatic abilities. (Pre-Emptive Strike with its triggered missiles, Carpet of Spikes with its periodical Spike Storms, Bomb Blitz with its global destruction when bloons leaked, Elite Defender with its x4 attack speed when bloons leaked, Legend of the Night with its black hole, and Commanche Defense calling backup Comanches)
    • However, it can be seen as an attack especially since it has no cooldown.
      • The latter three's passive abilities are affected by Energizer, but Pre-Emptive Strike does not get affected.
  • Before Version 20.0, the description for Pre-Emptive Strike was "Automatically triggers a MOAB Assassin effect whenever MOAB-Class Bloon spawns from the Bloon entrance" but was changed to "triggers a powerful missle attack" with the typo. The wiki description for the Version 20.0 Pre-Emptive Strike uses the correct spelling, but this was officially fixed by NK themselves in the game by Version 21.0.
