Targeting Priorities[]

Like all Monkey Aces, Rapid Fire uses flight patterns as its targeting priority settings.

  • Circle: Flight pattern becomes a circular path around the runway.
  • Figure Infinite: Flight pattern becomes the shape of the infinite symbol (∞). As the Monkey Ace flies, it will pass its runway during its flight, specifically at each half of the whole flight path.
  • Figure Eight: Flight pattern becomes the shape of the number 8. As the Monkey Ace flies, it will pass its runway during its flight, specifically at each half of the whole flight path.
  • Wingmonkey: Instead of a fixed flight path, the Monkey Ace will attempt to fly as close to the path as possible, similarly to an Aircraft Carrier Plane. Available only via the Wingmonkey MK.
  • Reverse Flight: Shown by an icon of a reverse aircraft, the Ace will reverse direction of flight. Unlike other target priorities such as Change Hands, there is a cooldown of 5 seconds before being able to reverse flight direction again. It can be coupled with all flight options except Wingmonkey.

Rapid Fire can also receive the Centered Path targeting option when given the 1-0-2 crosspath.

The Rapid Fire upgrade increases attack speed for the Monkey Ace, allowing them to attack more often. Although the timing at which the Ace may deploy weapons may seem like it is disrupted, strictly speaking an attack speed increase is actually overall better for the Monkey Ace, because adding more attack speed will increase the consistency of its attacks too. Therefore, more weapons can be deployed per second, increasing damage potential of the Monkey Ace.


Version History[]

Rapid Fire's base attack speed bonus has been reduced, but overall attack speed with this upgrade is exactly the same. Therefore, it was not nerfed overall, but rather buffed overall because of another buff inherited into the base Monkey Ace.

  • Change Rapid Fire attack rate buff decreased (0.6x → 0.75x). Base attack speed remains the same.
  • Buff Monkey Ace dart projectile size increased (2 → 3).
More of a straight quality of life, Ace has gained a new special toggle button to allow it to turn back and fly in reverse on any selected flight pattern. [...]
~ Ninja Kiwi, referring to Reverse Flight
  • Buff Monkey Ace can now toggle flight direction for any pattern.

  • Despite being the 3rd upgrade in BTD4, it became the first upgrade in each path in BTD5 and BTD6.
  • Prior to Version 23.0, there was a special case for Spectre and Flying Fortress that increased their attack speeds by only +33% instead of +66% for all other upgrades. This has since changed to a plain +33% for all since then.
