New central flight path for maximum map coverage.
~ In-game description

Centered Path is the second upgrade of Path 3 for the Monkey Ace in Bloons TD 6. It adds a new targeting option "Centered Path" that sends the Monkey Ace along a circular path around a point (located at the center of the map by default). It does not matter where the Monkey Ace landing pad is for a Monkey Ace set to Centered Path; by default, they will all loop around the same path, albeit different parts of the loop depending on timing at which the player changes the loop setting.

Starting from Version 27.0, the center of the Centered Path loop can be manually changed per Monkey Ace. This allows it to be locked into a loop anywhere on screen at the player's own will.

This upgrade costs $255 on Easy, $300 on Medium, $325 on Hard, and $360 on Impoppable.



The aircraft gains a full red coating throughout, only leaving out the blue rings on each side of the upper biplane wing.



Targeting Priorities[]

Like all Monkey Aces, Centered Path uses flight patterns as its targeting priority settings. The upgrade Centered Path automatically unlocks the Centered Path targeting option.

  • 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.
  • Centered Path: Flight path becomes a large circular path, centered around the center of the map by default. The center of the flight path can be changed manually. Can be accessed by purchasing the Centered Path upgrade, and once upgraded the Ace defaults to this target priority.
  • 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.

Like most Monkey Aces, Centered Path shoots darts in a zone-like fashion while having Path-Based Mobility.

Centered Path adds an extra flight path that encourages free movement of Monkey Aces, letting them become less limited by placement of the Monkey Ace landing pads. Adequate timing of the Aces to align on the path smoothly might be necessary to optimize this upgrade, but purchasing this upgrade is very helpful on certain maps with good overall central circular track coverage.

The option to choose the center of the loop now makes it possible to make a creative method of Ace micro based on Centered Path repositioning.


  • Besides just being an extra flight option, this upgrade is substantially useful on maps such as Park Path or Pat's Pond, although it is exceptionally more useful on the former due to how much more map coverage is utilized. On Park Path, 0-3-2 Bomber Aces can benefit a lot from this upgrade.
  • Monkey Ace upgrades that benefit the most from this target priority are the Upper Path 3 upgrades (Neva-Miss Targeting, Spectre, and Flying Fortress) and Sky Shredder. While utilizing just the plain middle Centered Path is helpful, a majority of the Centered Path's power comes from extreme micromanagement of the Centered Path centerpoints.
  • In the absence of utilizing extreme Centered Path micro, Upper Path 2 benefits little from this target priority, because the Centered Path upgrade misses out on purchasing Rapid Fire.

Version History[]

Gained a functional change in Version 27.0 to improve fixed mobility and likely to give more reason for this upgrade over just Sharper Darts. In fact, this has lead to higher-skilled Ace micro players to utilize Centered Path as a new form of Ace micromanagement.

  • Buff Monkey Ace dart projectile size increased (2 → 3).
  • Buff Monkey Ace attack cooldown reduced (2.1s → 1.68s).
Now allows you to find your center. Very zen.
~ Ninja Kiwi
  • Buff Centered Path now allows players to set the path's center to be anywhere on the map, much like the Heli Pilot's Lock in Place targeting priority.
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.

  • This upgrade is one of many upgrades spelled in American English. What makes this fact interesting is that Ninja Kiwi is a New Zealand company, despite primarily using British English, especially when "-re" words are normally spelled as "-re" in New Zealand instead of the American "-er" (e.g. "meter" for "metre", or in this case, "center" for "centre").
  • According to the upgrade filename, this upgrade was originally titled Flight Orders. Revealed in an NK blog post, the upgrade was planned to allow the player to create their own flight path. It was changed for being "confusing, visually unappealing and honestly a bit overpowered."
  • The Version 27.0 buff to Centered Path has eventually lead to players in Version 28.3 to do multiple 2MPC completions with Ace with this upgrade. 3-0-2 Fighter Plane came first, followed by 0-3-2 Bomber Ace, and lastly 2-0-2 Ace.
