Razor Rotor blades rip up Bloons on contact, including Lead and Frozen Bloons.
~ In-game description

Razor Rotors is the third upgrade of Path 1 for the Heli Pilot in Bloons TD 6. It allows the Heli Pilot's sharp rotors to hit bloons on contact, popping and dealing 2 damage every 0.75s within a radius of 35. The Razor Rotor attack can also pop Lead Bloons and Frozen Bloons. Razor Rotors have 10 pierce per cycle.

Starting from Version 31.0, the Pursuit targeting is modified to set the Heli to follow much closer to the bloon, approaching much closer to the bloon while still advancing slightly ahead of the bloon, and is exclusive to this Tier 3 upgrade to highlight the razor rotor attack.

This upgrade costs $1,485 on Easy, $1,750 on Medium, $1,890 on Hard, and $2,100 on Impoppable.

Description[]

Appearance[]

Razor Rotors adds the eponymous rotors to the Heli, adding a light grey sharp edge to the end of each rotor. It also extends the wings outward and adds a red stripe to both of them, and gives the Heli a sharper nose.

Path 2 crosspathing adds an additional yellow and green tail rotor, then paints the ends of the wings yellow.

Path 3 crosspathing adds a yellow or green chevron to each wing.

Mechanics[]

Razor Rotors gains the eponymous attack, which functions as a source of Contact Damage, dealing 2 damage with up to 10 pierce every 0.75 seconds; the Rotors are also Normal type, able to pop any bloon type.

It additionally has a unique mechanic involving Pursuit: the Heli Pilot now moves much closer to the front of the first bloon, therefore allowing the Razor Rotors to deal their damage more consistently with Pursuit active.

Costs[]

Strategy[]

Summary[]

Razor Rotors provides some extra grouped popping power that the Heli Pilot may tend to lack in its earlier upgrades. Compared to other anti-lead options, Razor Rotors is quite expensive, but with the extra damage buff in Version 24.0 it is quite effective as area-of-effect with mobility.

Tips[]

  • Razor Rotors is best used when not in Pursuit Mode. Instead, it is better off to micromanage the Heli Pilot by manually flying the Heli Pilot over the target bloons, especially Lead Bloons.
    • Compared to BTD5 Mobile, Pursuit Mode is not nearly as negative when paired with Razor Rotors. In BTD6, setting a Heli Pilot on Pursuit will make it follow just in front of the bloons.
  • Crosspathing does not benefit the Razor Rotors attack, with exception of 3-2-0 for camo detection. Use whatever crosspath helps the Heli Pilot's other attacks, or 3-2-0 for hitting Camo Leads.

Version History[]

The strength of Razor Rotors was initially similar to how it was in BTD5 when it was first released in BTD6. It was buffed later on to improve its blade reliability when interacting with Pursuit targeting, and gained extra damage to make it more worth the price as an area-of-effect with mobility. Since Pursuit had previously felt counterintuitive for Razor Rotors, Pursuit was reworked exclusively for Razor Rotors to go much closer to the bloons.

20.0
[...] On the opposite end of the spectrum, Pursuit Razor Rotors has underperformed due to distancing itself far too much, so we increased the range of this attack slightly.
~ Ninja Kiwi
  • Buff Razor Rotors razor blade range increased (33 → 35).
24.0
Razor Rotors doesn't synergize well with it's own T2 and is kinda the dunce of T3 Helis
~ Ninja Kiwi
  • Buff Razor Rotors blades deal more damage (1 → 2).
31.0
Previously Razor Rotor’s used to make the heli pursue for a further distance & this caused it to often fail to reach Lead Bloons with the rotor attack that could pop them. This overall seemed like a design flaw so that back-off distance has been moved up to the T4 instead.
~ Ninja Kiwi
  • Change Razor Rotors set on Pursuit now flies much closer to the targeted bloon in front. Does not apply to Apache Dartship or Apache Prime.
    • Buff This is an overall buff to T3 Razor Rotors, whose main purpose is to utilize the razor rotor.

Trivia[]

  • In BTD6, the Razor Rotors Heli Pilot will intentionally tilt towards the bloons to shred bloons. Similar behavior occurs for Apache Dartship and Apache Prime.
