Shoots a blob of sticky glue that slows Bloons down by 50%
~ In-game Description

The Glue Gunner is a Primary-class tower in Bloons TD 6 that shoots glue which slows down Bloons. The tower retains its name and role from the Bloons TD 4, and 5 game generations, with significant additions. It did not receive any teasers prior to release, but it was first shown when the game was available to select YouTubers several days before BTD6's official release date.

Initially, the Glue Gunner shoots a non-damaging glob of glue every 1.0s, sticking onto one bloon per glob. Glue can soak through up to 3 non-blimp layers (more with Glue Soak), slows the affected bloon by 50%, and the slowdown effect lasts up to 11 seconds. Various upgrades increase the potency of the glue, including a corrosive formula, splatters of glue, and slowdown of MOAB-class bloons. All glues are governed by a glue prioritization system; "stronger" glues are prioritized first and can override any weaker glues, with some exceptions.

It costs $235 on Easy, $275 on Medium, $295 on Hard, and $330 on Impoppable.


The Glue Gunner holds a large cannister of glue on its back, and the monkey holds the nozzle and trigger with its right and left hands, respectively. He looks not too different compared to his BTD5 counterpart outside of having the general BTD6 art style. There are minor differences to the Glue Gunner's visual appearance, however.

Visually, the Glue Gunner looks very similar to its BTD5 counterparts, but with minor differences. The tube connected to the hose now has a greener colour and shadings, which makes it more realistic. The yellow glue container now has an extra mini rope which acts as a strap for the monkey to wear it like a backpack, there appear to be screwed on the metal band around the container, and the hose is spewing glue in the artwork but it shoots a blob in other games' art while the gameplay itself is still the same. Otherwise, there are little changes, if any to the tower.

The Glue Gunner has gained a significant overhaul of buffs that make it viable across a variety of different roles. As an unupgraded tower, its basic glue shots can now soak through 3 layers of bloon instead of just 1 and can be applied to MOAB Class bloons, provided MOAB Glue or Corrosive Glue is purchased. Upgrading to Glue Soak allows the soaking of all layers, just like the original version. Upgrading it to Corrosive Glue or higher can also damage MOAB-Class, enhancing its use in gameplay capabilities, but it cannot slow them down without the MOAB Glue upgrade.

Path 1 increases the power of the glue's penetration potential and deadliness. Glue Soak allows glue to soak all bloon layers, forcing the bloons to undergo the glue status forever until unglued. Corrosive Glue slowly corrodes any affected bloons every few seconds, and can now target and stick onto MOAB-class bloons with half glue duration and no slowdown. Bloon Dissolver is formulated into a much more powerful solvent, increasing its corrosion rate for stronger cleanup against regular bloons. Bloon Liquefier once again improves the solvents in the glue by increasing the corrosion rate of the glue and affecting additional bloons too. Lastly, The Bloon Solver provides the ultimate toxic mixture of sticky green glue, spraying out splashes of the most corrosive solvents at super fast speeds.

Path 2 deals with increasing the distribution of glue. Most of these upgrades along this path involve increasing the rate of applying glue by means of extra pierce to each shot. Bigger Globs allows each shot of glue to hit one more bloon per shot. Glue Splatter converts the glue into a splash of glue, for an even greater amount of pierce. Glue Hose increases the attack speed of the Glue Gunner to distribute the glue even faster. Glue Strike adds an ability that drops a quick rain of glue over the whole screen, making all affected bloons vulnerable to extra damage while glued. Glue Storm further improves of its ability by creating a persistent storm of icky sticky glue.

Path 3 specializes in improving the stickiness of the glue. Stickier Glue is now on a separate upgrade path, and begins this path by improving the lifespan of the glue. Stronger Glue improves the slowdown of the glue from 50% to 75%, for even slower bloons. MOAB Glue modifies the glue into a bubblegum-like substance that can stick to and slow MOAB-class bloons, although with a weaker slowdown effect and duration. Relentless Glue increases potency of the glue by allowing bloons directly glued by the Glue Gunner to drop blobs of glue onto the track for other bloons to pick up. The strongest, most unstoppable glue comes from the Super Glue, greatly reducing the speed of all affected bloons to an extremely slow speed.

One significant note is the Glue Gunner's major weakness to BADs, due to not applying any slowdown effect onto them regardless of upgrades. Besides this, the Glue Gunner is a highly versatile support-oriented tower across a wide variety of different aspects.

The Glue Gunner is classed as a Primary Monkey.

Target Priorities[]

The base Glue Gunner uses the standard target priorities: First, Last, Close, Strong. Many of the Glue Gunner's alternate attacks have target priorities that are integrated into the Glue's own target priorities. Glue Gunners will not attack bloons glued by their own glue attacks and will instead prioritize gluing new ones, except in the Super Glue's case, where it will attack any bloon that isn't immobilized rather than glued.

  • First: Targets the first bloon visible within its range.
  • Last: Targets the last bloon visible within its range.
  • Close: Targets the closest bloon visible within its range.
  • Strong: Targets the strongest bloon visible within its range.

Alternate attacks have a different set of target priorities:

  • Glue Strike and Glue Storm target all bloons on screen.
  • Relentless Glue's track blobs always target onto bloon track lanes every time an affected bloon is popped.

Glue Prioritization System[]

In Bloons TD 6, there is a glue prioritization system. This system tells the Glue Gunner if it should ignore a bloon with a different glue or apply its own glue on it. Bloons can have multiple glue types, but some effects are dictated by the last applied glue, so the prioritization system is made in an attempt to let bloons become applied with a more valuable glue, which should reduce the possibility for potentially disadvantageous glue synergies.

Before around Version 25.0, the glue prioritization system worked like this:

Note: Data gathered during version 15.1

Glue gunner priority sytem chart (old).png

After the release of Version 25.0, which appeared to have reworked the glue prioritization system, the system works more like this:

Glue gunner priority sytem chart (new).png

Bloon speed depends on the last applied glue until it expires (x-4-x Glue Strike and x-5-x Glue Storm abilities will not affect the speed of already glued bloons), damage effects can stack as long as they are of different path 1 tiers (2-x-x Corrosive Glue , 3-x-x Bloon Dissolver and 4-x-x Bloon Liquefier), however, both x-x-5 Super Glue and 5-x-x The Bloon Solver will remove any current glue on the target (this won't take away the x-x-4 Relentless Glue, Glue Strike and Glue Storm effects).

Special Crosspathing Interactions[]

Special Crosspathing Changes
  • 2-0-5 Super Glue: Super Glue damage-over-time becomes 1 damage every 2.0s instead of 1 damage every 2.3s
  • Glue Storm + Path 3: Glue Storm ability glue lasts for 48 seconds on the affected bloon with Stickier Glue and slows by 87.5% with Stronger Glue.
  • 5-2-0 The Bloon Solver: increases pierce by +5, for a total of 11 pierce.
  • 0-2-5 Super Glue : increases pierce by +5, for a total of 11 pierce, and converts attack to be a splash.
Other Important Notes
  • Glue Gunner + Corrosive Glue: Adding Corrosive Glue to any upgrade allows targeting of MOAB-class
  • Corrosive Glue and/or MOAB Glue: Glue effects last half as long on MOAB-class bloons regardless of which upgrades are bought
  • Glue Soak: Even with upgrades that allow sticking of MOAB-class, such as 1-0-3 MOAB Glue, Glue Soak does not soak through MOAB-class bloons. This also includes upgrades that add corrosion to the glue.
  • Relentless Glue + Path 2: Pierce buffs do not directly affect the glue track blobs.

The Bloon Solver recently received a small functional rework buff, this follow-up buff will make the stepping stones to it a little easier on saving.
~ Ninja Kiwi
  • Buff 4-x-x Bloon Liquifier price reduced from $6,500 → $5,500.
Glue Strike currently allows for 240 crosspath to hit MOABs with 042 being more Ceramic focused but losing the Glue Soak from top path hurts against lower layers, so we've increased the base amount of layers glued by Strike & Storm so that it won't expire on non-MOABs so quickly. Additional changes are a follow up reduction to The Bloon Solver's price and a small increase to MOAB Glue's price due to dominance in conjunction with MOAB Press.
~ Ninja Kiwi
  • Buff The Bloon Solver price reduced from $24,000 to $22,000.
  • Buff 0-4-x Glue Strike ability layers glued increased from 3 to 6.
  • Buff 0-5-x Glue Storm ability layers glued increased from 3 to 9.
  • Nerf MOAB Glue price increased from $3200 to $3400.
Adjustments to top-path upgrades to make each step more noticeable. Very small nerf to the slow amount on MOAB Glue as it has for a long time held a dominating spot in MOAB support, but this same amount has been returned to the previous value at Tier 4. We are still looking at future improvements here, including reworking the priority tree of glue stacks.
~ Ninja Kiwi
  • Buff Bloon Dissolver price reduced ($2,700 → $2,600).
  • Buff Bloon Liquifier pierce increased (1 → 2).
  • Nerf MOAB Glue slow amount on MOABs reduced (0.625x → 0.75x). Remains at 0.625x for Relentless Glue.
More tweaks with the intent of viable stepping stones toward The Bloon Solver. Due to quirks with game state interactions temporarily preventing more nuanced changes, we have decided to leave MOAB Glue's slow amount on MOABs as it was previously, coming back to Relentless later. However xx4 Relentless Glue will still layer over the top of it.
~ Ninja Kiwi
  • Buff Bloon Dissolver costs less ($2,600 → $2,500).
  • Buff Bloon Liquefier costs less ($5,500 → $5,000).
  • Buff MOAB Glue MOAB slow effectiveness changed from 0.75x back to 0.625x (i.e. now slows blimps by 37.5% again).
  • Nerf [undocumented bug] Super Glue can no longer re-apply glue onto the same bloon or blimp until the glue wears out.
Super Glue currently fits a role of essentially a weaker Ice Impale that is also much more expensive (and, well, worse). For now the cost has been cut substantially to keep their function and value balanced.
~ Ninja Kiwi
  • Buff Super Glue price reduced from $35,000 to $28,000.
  • Buff [undocumented] Super Glue will now re-apply glue to glued bloons without the "Slowdown Stuck" status effect. Still does not re-apply glue to "Slowdown Stuck" bloons
    • This was listed as a bug fix that was said by NK as "xx5 Super Glue can now re-target Bloons that is has [sic] already Glued after stun expires"
Acidic Mixture Dip did nothing for Glue Gunners but alchemist would waste it on them
~ Ninja Kiwi
  • Buff Acidic Mixture Dip can no longer be thrown at Glue Gunners, which never gained any meaningful effect from it.
Since glue gunners can't work together as we all want them to and we could not bite that off for this update, for now have decided to do more for the top and middle paths themselves.

Bloon Solver's single target power feels like it ramps slowly on larger targets, and while it is mainly a grouped cleanup, we decided to give a nudge here with bonuses to large targets to help with higher round falloff.

~ Ninja Kiwi
  • Buff Bloon Liquefier DoT deals +1 damage to ceramics
  • Buff Bloon Solver DoT deals +1 damage to MOAB-Class
Glue Strike doesn't seem to hold up to any other option in a similar role, so we've doubled down on its support factor with a new role and are hoping for more synergy to emerge there.
~ Ninja Kiwi
  • Buff Glue Strike ability now weakens Lead Bloons, allowing them to take sharp damage
  • Buff Glue Strike bonus damage taken while glued increased from 1 → 2
  • Buff Glue Storm bonus damage taken while glued increased from 1 → 2
  • Nerf Super Glue now re-applies to glue to "Slowdown Stuck" bloons
    • Note: Considered a nerf because this causes blimp descendents to clog pierce instead of focusing on other blimps that were unaffected by the "Slowdown Stuck" status effect.

Bug Fixes and General Changes[]

  • 2-x-x Corrosive Glue upgrade will now last the correct duration on MOABs.
  • Buff x-2-5 Super Glue with Glue Splatter now correctly has more pierce (5 → 6).
  • Change 2+-x-x Corrosive Glue will now correctly apply Glue Soak to bloons when replacing a weaker glue that is already on a bloon.
  • Glue Gunner should now work correctly on Chutes.
  • Buff x-2-5 Super Glue with Glue Splatter should correctly stun all regular Bloons.
  • Nerf x-5-x Glue Storm ability no longer glues MOABs without 2-x-x Corrosive Glue.
  • Glue Storm description updated to reflect previous changes.
  • Buff 4-1-0 Bloon Liquifier can now correctly pierce through 3 Bloons, not just 2.
  • 4-x-x Bloon Liquifier description has been updated with more detail.
  • x-4-x Glue Strike description has been updated with more detail.
  • Buff Super Glue can now re-target Bloons that is has already glued after "stun" expires.

  • Buff 2xx Corrosive Glue and above now allows the top path of Glue Gunner to be targeted by Acidic Mixture Dip
  • Nerf Super Glue now targets "Slowdown Stuck" bloons again
    • Written by NK as "xx5 Super Glue can target Glued Bloons again"


When attacking:


Official artwork[]



  • In BTD6, a glued bloon can be glued by another glue gunner.
  • Path 1 upgrades improve its ability to pop bloons while Path 2 upgrades improve its ability to glue multiple bloons at a time. Path 3 focuses on slowing bloons down even more, as well as gluing MOAB Class Bloons.
  • Tier 2 upgrades make the body of the glue gunner almost completely covered. At tier 3 the face gets covered.
  • In Bloons TD 6, each 5th tier upgrade has a different suit. In Path 1, the monkey wears a green Class-B hazmat suit with a gas mask connected with an oxygen tank meaning the fumes are very toxic. In Path 2, the monkey wears an orange mask with two windows for eyes. In Path 3, the monkey wears a black (sort of metallic) Class-C hazmat suit.
  • In BTD6, by the end of path 1, the glue becomes green, by the end of path 2 the glue remains yellow, and by the end of path 3, the glue becomes pink.
  • In BTD6, the monkey has noticeably darker fur than other monkeys.
  • In BTD6, the Glue Gunner is the only tower that changes poses from Tier 1 to Tier 2.
