~ In-game description

Quad Darts is the first upgrade on the first path for the Heli Pilot in Bloons TD 6. The Heli Pilot now shoots 4 darts per volley instead of 2. These four darts count as two separate twin-dart attacks, not one integrated quad-dart attack, and both dart attacks always attack simultaneously.

This upgrade costs $680 on Easy, $800 on Medium, $865 on Hard, and $960 on Impoppable. If this tower is nearby Level 6+ Rosalia's workshop, this upgrade costs $??? on Easy, $760 on Medium, $??? on Hard, and $??? on Impoppable.

Quad Darts shooting quad darts

Heli Pilot with Quad Darts receives a total of four guns, the two added guns on the sides of the helicopter. The four guns technically count as two separate twin-gun attacks, with the positions locked into different spawn points and forcefully shooting simultaneously with each other.

All crosspaths of Quad Darts receive a total of four guns, consistent with the name of the Quad Darts upgrade.

Targeting Priorities[]

Quad Darts utilizes touch-based mobility and self-mobility to move around the screen with different flight targetings. Its main attack shoots straight movement projectiles, which originate from the Heli Pilot with its independent range like an ordinary tower.

  • Follow Touch / Follow Mouse: Moves to where the player taps. On desktop versions, Follow Touch instead becomes Follow Mouse, which will make the Heli Pilot move to wherever the cursor is currently at.
  • Lock In Place: Stops the Heli Pilot where it is when the Target Priority is selected. Can be adjusted to choose a different locked location.
  • Patrol: Patrols between two spots chosen by the player. Can be adjusted to choose different points.
  • Pursuit: Equivalent to the target priority First, except the Heli Pilot will follow in front of the bloons while shooting them. It is unlocked with the purchase of the second upgrade on the first path, with the same name as the target priority. Once upgraded to the respective upgrade, it automatically switches to this target priority.

The Heli Pilot's main attacks always default on First based on the range of the helicopter's weaponry.

Generally, Quad Darts is used as an early-game upgrade when using the base Heli Pilot. Similarly to the lower tier, the base Heli Pilot finds most use on long tracks and maps where the infinite range is appreciated.


  • For the middle path Heli, the Quad Darts path offers more early-game damage and the ability to buy the next upgrade, Pursuit. Otherwise, try to go for Faster Darts and Faster Firing as they will boost the effectiveness of Downdraft and the Marine from Special Poperations.
  • For MOAB Shove, it may be better to not buy Quad Darts so that it can stall blimps for longer, but for Comanche Defense and Comanche Commander this crosspath will be the best as they are DPS-oriented and can obtain camo detection from external means.
  • Note that Quad Darts attacks actually count as two independent twin gun shots, not one quad gun shot. So an Alch buff can be consumed on Quad Darts twice as fast as a Heli without that upgrade.

Version History[]

Balance Changes[]

Quad Darts has not been changed since it was first released, but it is now more expensive compared to its BTD5 counterpart.

Initial release
  • NERF Quad Darts costs more ($600 → $800)
Heli Pilot manages on pursuit far too easily without any need to consider Bigger Jets unless camo or downdraft is required. For more crosspath variety than just 'camo' we moved more of the base Heli speed out and back into Bigger Jets with an overall buff to Bigger Jets. This should allow Bigger Jets to scale a little better than other helis through early speed ramping. [...]
~ Ninja Kiwi, referring to base Heli flight speed versus Bigger Jets
  • NERF Affected by base Heli flight speed nerf versus Bigger Jets crosspathing

Bug Fixes and General Changes[]

Extra Notes (Version History)[]


Official artwork[]


  • When the entire list of BTD6 tower upgrades are listed alphabetically, the Pursuit upgrade comes right before Quad Darts.
  • Quad Darts is the only returning Heli Pilot upgrade below Tier 3 to be more expensive on initial release.
