This game has a prerelease article

This game is still under active development.
Be aware that any unused content you find may become used or removed in the future. Please only add things to the article that are unlikely to ever be used, or went unused for some time. If they do get used, please remove them from the page and specify in the edit summary!

This article is a work in progress.
...Well, all the articles here are, in a way. But this one moreso, and the article may contain incomplete information and editor's notes.

Bloons Tower Defense 6 is, unsurprisingly, the sequel to Bloons Tower Defense 5. But this time, it's in 3D!

To do:

There are several freeplay rounds with custom layouts that are functionally impossible to reach (such as round 10,000, which always has 100 Fortified BADs).
There are some oddities with the Ice Monkey that suggest that it was originally planned to be a magic-class tower instead of a primary-class tower:
- Some of its weapons are flagged as belonging to a magic tower instead of a primary tower.
- The game forcibly crashes if a tower is given an upgrade combination that is normally impossible (such as 3-3-3), but the Wizard Monkey, Druid, and Alchemist won't cause a crash if at least two of the paths are tier-2 or below (such as 3-2-2), because these towers are meant to work with the Monkey Academy's Wizards Library upgrade. However, this trait is also shared by the Ice Monkey, suggesting that this tower was also planned to be affected by Wizards Library.
More unused graphics and models that got taken out in version 24.0.
Document the prototype builds have been uncovered, such as builds 71 and 102.
See if there is a better image of Sniper Monkey's concept art.
Assets and other data unique to Bloons TD 6+ (the Apple Arcade version) are also found in the game files of original BTD6.
An unused quest dialogue for Race Mode appears in the CSV file for version 36.0.

Unused Tracks

Monkeys in Space

This track was allegedly cut from the final game because one of the founders of Ninja Kiwi, Stephen Harris, does not like space maps. It was going to be Intermediate difficulty. The model for the track was removed in version 24.0, while the textures and thumbnail for the track only existed in early builds.

BTD1

As the name suggests, this is a recreation of the track from the very first Bloons Tower Defense game. This was most likely used for testing. The thumbnail for the track only exists in builds from early 2018, though the thumbnail itself seems to be a remnant from an even earlier build. In the early 2018 builds, the map model included several decorative objects for testing purposes, such as houses, flowers, and a windmill, the models of which were later used for other maps such as Monkey Meadow and Town Center.

Test Maps

There are two additional test tracks, TestMap and TestWaterMap, both of which have the same path layout as BTD1. TestWaterMap has a mask (defined area for tower placement, such as the path or the ground) entirely of water, while TestMap has no mask at all.

Unused Graphics

Extreme Icon

An icon for the Extreme track category, which was previously seen in BTD5. Interestingly, while this icon is not used anywhere in-game, the official Ninja Kiwi Discord server used to use this icon as an emote.

Hero Level Badges

HeroLevelBadge01
HeroLevelBadge02
HeroLevelBadge05

Seven different icons exist for Hero levels, but only icons 3, 4, 6, and 7 are used in-game, leaving icons 1, 2, and 5 unused.

Instamonkey Icons

Some of the instamonkey icons feature tower designs are different from the final designs.

Moderately different from final, featuring minor differences such as the orange stripe on the gun being longer, the googles being sharper, and the addition of a bipod on the bottom of the gun. It's armor is also seemingly orange instead of grey.

Elite Defender Buff Icons

BuffIconSniperLeakxx5
BuffIconSniperDistancexx5

Buff icons for the Elite Defender's passive abilities. These have existed since version 12.0, but have never been used.

Jungle's Bounty Buff Icon

BuffIconDruidx4x

A buff icon for the Jungle's Bounty. It was never used.

Monkeyopolis Buff Icon

A buff icon for Monkeyopolis. It is unused as this upgrade gives no buffs outside the ones its component upgrades give.

Early Beast Handler Buff Icons

BuffIconBeastHandlerFish
BuffIconBeastHandlerDino
BuffIconBeastHandlerBird

Early beast buff icons for the then-upcoming Beast Handler tower which briefly existed in version 34.0. After the release of the Beast Handler on version 36.0, these icons were replaced by white silhouettes of the beasts on purple circles to better fit the Beast Power-based merging mechanic.

Relic Knowledge Buff Icons

BuffIconAirAndSea
BuffIconFlintTips

Two buff icons for two Relic Knowledge Points that are present in the game. However, the buff icons themselves are not seen in-game.

Paragon Power Totem Buff Icon

A buff icon for Paragon Power Totems. Their increasing in a paragon's degree is indirect, although the presence of an icon may suggest they served a different purpose earlier on.

Fortified Bloons

This needs some investigation.
Discuss ideas and findings on the talk page.
Specifically: These bloons were functional at one point, but were removed in a later update. When were they removed?

	Red	Blue	Green	Yellow	Pink	Purple	White	Black	Zebra	Rainbow
Fortified
Regrow Fortified
Camo Fortified
Camo Regrow Fortified

Fortified variants used to exist for every Bloon type in the game, but only Lead, Ceramic, Golden, and MOAB-class Bloons can be fortified in the current version of the game. Fortified Purple Bloons could appear in freeplay mode at launch, but this was removed in version 2.0. These Bloons were made non-functional in an unknown version, and their graphics were removed in version 24.0.

Shielded Bloon

This overlay texture was added to the game's files in version 24.0, but was never used. It may have been intended as an ability of the Golden Bloon, possibly as a nod to Bloons Super Monkey 2 where it was always protected by a shield.

A very similar graphic would later be used for the Shielded Bloons in Bloons Pop!.

Early Churchill Texture

Early	Final

Early textures for Captain Churchill. These textures are less polished than the final textures, and they bear a striking resemblance to his appearance in an early render. These textures don't fit Churchill's model or UVs in the final game, which indicates that Churchill also had a different model at one point.

Early Crate Textures

The Support Chinook's texture map contains placeholder textures for crates. The cash crate texture uses the icon for NK Coins, the currency formerly used on Ninja Kiwi's website, while the lives crate texture reuses a heart icon from BTD5.

There are also early supply drop crates found in the Sniper Monkey's texture map in a Bloons TD 6 prototype, which are rougher than the final. Interestingly, there features what seems to be the Sniper Monkey's concept art! Unfortunately, it is covered up and low quality. From what little can be seen, the crates in the concept art are identical to the early crates, the snipers the upgrades use are below them, and an Operation: Dart Storm is above to the left, deploying the supply crate. There is also slight design changes of the guns; the gun for Even Faster Firing has a different design, having only one orange stripe instead of 2.

Early Dartling Gunner Textures

LaserCannon
LaserCannonPlasma
DartlingPlasmaBeam
DartlingPlasmaHead
PlasmaAcceleratorBeamBody
RayOfDoomBeamBody
DepletedBloontoniumDart
HydraRocketPod
RocketStormRocket
MADRockets
Buckshot
PlasmaBuckshot

An assortment of projectile textures and visual effects that were originally intended for the Dartling Gunner. These were added to the game's files in version 9.0, but were removed in version 12.0. The Dartling Gunner was later released in version 22.0, but the projectile textures it now uses are completely different, leaving these early designs unused.

Rocket

ProjectileRocket, AAMissileSprite, TankShellDouble, TankShellTrebble

This weird-looking texture for a rocket projectile has three duplicates. Most likely a placeholder texture, given its ubiquity. Removed in version 24.0.

Bullet

Bullet

The same graphic as the above, but grayscale and with the bottom half cut off for some reason. Also removed in version 24.0.

Early Monkey Ace Projectiles

DartSprite
DartGreenSprite
FighterPlaneSprite
PineappleSprite
BomberAceSprite
GroundZeroSprite
TsarBombaSprite
SpectreSprite

A number of early, strange-looking textures for the Monkey Ace's projectiles.

Blue Shuriken

SeekingShuriken, SharpSeekingShuriken

A blue shuriken. It seems that the Ninja Monkey would have used this when upgraded to Seeking Shurikens, rather than using the regular shuriken textures, as it does in the final. Similarly, a second texture was supposed to be used for having both Seeking Shurikens and Sharper Shurikens at the same time, but is also unused and, oddly, is completely identical to the blue shuriken. Both were removed in version 24.0.

Unused Audio

Marine walkie-talkie sounds

Two sounds associated with the Marine ability for the Special Poperations Heli Pilot. They were removed in version 22.0 due to unknown reasons.

(Source: Bloons Wiki)

Beast Handler sounds

The Beast Handler has many sounds that are associated with beasts of a specific terrain type or size. However, two sounds, namely a sound for small land beast placement and a sound for medium water beast upgrade, are unused.
