Bloons TD 6/Version Differences

This is a sub-page of Bloons TD 6.

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.

To do: Versions 21.0 to 37.0 and 39.0 to 40.0

This needs some investigation. Discuss ideas and findings on the talk page. Specifically: see below In older versions, the background music would speed up on higher rounds. When was this removed? Are there any known differences between version 1.0.1 (the version released to certain YouTubers a few days before launch) and 1.3? If so, those would be worth documenting on a prerelease page. Console version differences?

Version 1.3

The original release. Yes, really, the first version was 1.3.

Version 1.5

Released on 18 June 2018. This was the first version released in Hong Kong, as, bafflingly, the game somehow missed the release date in that region. Consists of stability improvements and several bug fixes, mostly pertaining to glitchy interactions between towers.

Version 1.6

Released on 21 June 2018. Consists of bug fixes (largely to Monkey Knowledge) and the removal of a few "regrow farming" exploits that were missed during playtesting.

Version 1.7

Released on 28 June 2018.

• CHIMPS mode now rewards end-of-round cash like in most other modes.
• The Banana Farmer can now collect crates from Monkeyopolis.
• Replaying Daily Challenges no longer counts toward Daily Challenge-related Achievements.
• Load time improvements across the board, especially for the Powers menu.
• Bug fixes and performance improvements.

Version 1.8

Released on 29 June 2018. Fixes a single bug where the game would occasionally award the player with the wrong amount of Monkey Money for completing a game.

Version 2.0

Released on 23 July 2018. The first content update to the game.

• The 5th Hero, Captain Churchill, has been released. A preliminary icon and a full set of text for Churchill have existed in the game since launch, both of which have been updated to reflect alterations made to the Hero's design and upgrades since.

Launch	2.0+

• Churchill's original icon shows a rather drastic change in his design: his helmet was originally green instead of brown, his goggles were all-black instead of brown with green lenses, the barrel on his tank's gun was green instead of gray, the antenna on his tank didn't have a cap, and both his hat and the side of the tank's turret body had banana-themed emblems on them. Additionally, Churchill himself lacked a scar and had beady brown eyes instead of green eyes.
  • In addition to Churchill's used textures, this update also added some early Churchill textures, which match this early icon much more closely than the final textures do.

Level	Launch	2.0+	Notes
3	Armor Piercing Shells: Shots can pop Black Bloons and do extra damage to Ceramic or higher for 5 seconds.	Armor Piercing Shells: Shots can pop Black Bloons and do extra damage to Ceramic or higher for 10 seconds.	Armor Piercing Shells was buffed to last for 10 seconds instead of 5 in the final version.
14	Machine Gun pops 2 layers per bullet.	Machine Gun and Main Gun pop 2 layers per shot.	This upgrade increases the damage of both his Main Gun and Machine Gun in the final version, instead of just the Machine Gun.
20	MOAB Barrage shells do massively increased damage per hit.	MOAB Barrage shells and Main Gun do massively increased damage per hit.	MOAB Barrage was buffed to also increase the damage of his main attack for the duration of the ability at level 20 in the final version.

• A new intermediate track has been introduced: Firing Range. The text for this track has existed since launch.
• Patch notes are now able to be viewed in-game from the title screen. Previously, all patch notes were delivered exclusively via Reddit posts and on the developers' (now dead) forums.
• A news/events menu has been introduced.
• The Wizard Monkey's Soulbind upgrade, which was widely regarded as the single worst upgrade in the game by far, has been outright replaced with a completely different upgrade: Prince of Darkness. This upgrade uses the same portrait, icon, and model as Soulbind, but instead of sacrificing towers, the tower acts as a much stronger version of the Necromancer.
• All game modes now have their own medals. Before this, only Easy, Normal, Hard, and Impoppable had medals.
  • Tracks now display special borders if all medals are collected for them. A gold border is granted if the player has the Ruby (red) CHIMPS medal, while a black border is granted if the player has the Hematite (black) CHIMPS medal.
• Half Starting Cash mode has been replaced with Half Cash mode, which halves all cash earned instead of just starting cash.
  • Half Cash is unlocked after Double HP MOABs instead of before it due to the enormous jump in difficulty.
  • A new pop-up message appears when starting a game in Half Cash mode.
• Freeplay mode received unknown tweaks to make it "more interesting".
  • Fortified Purple Bloons no longer appear in Freeplay mode, rendering them unused.
• Continues now scale based on the round, costing more Monkey Money and providing more cash in higher rounds.
• Monkey Knowledge can now be toggled off via an option in the Monkey Knowledge menu.
• New animations have been added for removing objects. Before this update, removable objects would simply poof out of existence when removed.
• The cost of removing the statue on Rake has been increased from $350 to $1000.
• A few voice clips that Obyn was oddly missing (namely, the voice clips that warn of incoming MOAB-Class Bloons) have been implemented. However, he would not receive voice clips for popping MOAB-Class Bloons until version 10.0.
• The icons for the pre-existing Heroes have been updated. The original icons were mistakenly using earlier versions of their artwork.

Launch	2.0+

• Quincy's outline was lighter and he was positioned slightly further back.

Launch	2.0+

• The lighting on Gwendolin was different (being noticeably darker than the final version), her outline was darker, and her eyes were redrawn.

Launch	2.0+

• The shading on Obyn was very different and less defined, and his hands, horns, and the pattern on his head were slightly different.

Launch	2.0+

• The lighting on Striker Jones was different, his cap had a slightly different emblem, and his fabulous mustache was smaller and didn't obscure his mouth. This early version can also be seen in a teaser image posted on Twitter before launch.

• Balance changes and a ton of bug fixes, which can be viewed here.

Version 2.1

Released on 30 July 2018. Consists of bug fixes, mostly pertaining to Half Cash mode.

Version 3.0

Released on 23 August 2018.

• The 6th Hero, Benjamin, has been released. A preliminary icon and a full set of text for Benjamin have existed in the game since launch, both of which have been updated to reflect alterations made to the Hero's design and upgrades since.

Launch	3.0+

• Benjamin's original icon is slightly different: he was facing right instead of left, his hairstyle was different, and he had sunglasses in his level 1 form.
  • These differences closely match his appearance in concept art.

Level	Launch	3.0+	Notes
4	Generates $200 per round instead of $150.	Generates $150 per round instead of $100.	This upgrade generates less cash in the final version. The early text suggests that Benjamin would have generated more cash at level 1 than in the final version as well.
8	Income increased to $300 per round.	Income increased to $250 per round.	This upgrade generates less cash in the final version.
9	Bank hack increased to 8%	Bank hack increased to 12%	Bank Hack has a more significant upgrade in the final version.
10	Downgrades all newly spawned Bloons by 1 rank. Cash per pop from affected Bloons is double. Lasts 10 seconds.	Downgrades most newly spawned Bloons by 1 rank. Cash per pop from affected Bloons is double. Lasts 10 seconds.	The description for Syphon Funding at level 10 was changed to say "most" instead of "all", though it's not clear if this was a nerf to exclude BADs or just a correction.
11	Income increased to $350 per round.	Income increased to $300 per round.	This upgrade generates less cash in the final version. All cash generation upgrades after this are the same as the final version.
18	Bloon Trojan can affect DDT Bloons.	Bloon Trojan can affect BFB and DDT Bloons.	This upgrade was changed to allow Bloon Trojan to affect BFBs, but it's not known if Bloon Trojan was originally able to affect BFBs by default or not, making it unclear if this change is a buff or an accommodation to a Bloon Trojan nerf at lower levels.

• A new advanced track has been introduced: High Finance. The text for this track has existed since launch.
• A new Magic Monkey Knowledge upgrade has been introduced: There Can Be Only One. The text and icon for this upgrade have existed since launch.

• An option to respec Monkey Knowledge has been introduced, which costs 2000 Monkey Money.
• The lives cap has been raised from 1000 to 5000, though towers that generate lives are 95% less efficient after reaching 1000 lives.
• The Powers menu now has a tab to view the player's Insta-Monkey collection.

  • Frozen Over (beginner)
  • Haunted (intermediate)
  • Dark Castle (expert)

The text for all three of these tracks has existed since launch.

• A new music track has been introduced, which currently only plays on Frozen Over.
  • The track was originally named Winter is Coming on the official soundtrack, but was renamed to Winter Nights with the release of the Jukebox in version 17.0.
  • Internally, this track is named MusicCoopA-MusicCoopC, suggesting that it was originally intended for Co-op mode.
• Two new Powers have been introduced: Tech Bot and Energizing Totem.
• A new skin has been introduced for Quincy: Cyber Quincy.
• The main menu and all tracks have been given a Halloween reskin.
• A new holiday event-exclusive game mechanic has been introduced: collectibles will spawn on the track, which can be collected by the player, and after collecting at least 20, the player can activate a special ability that wipes out lots of Bloons.
  • In the case of Halloween, candies are the collectibles of choice, and the ability summons ghosts to run over the track.
• The 5-5-5 True Sun God (Avatar of the Vengeful Monkey) and its mini-Sun Avatars have new portraits. Before this update, they had the same portraits as the regular True Sun God and the regular Sun Avatar, respectively.
• A very large amount of assets pertaining to Co-op have been added to the game files in this update, though Co-op would not be introduced until version 11.0. A preliminary icon for Co-op has existed since launch, which has been replaced in this update.

Launch	5.0+

• The original Co-op icon is very clearly a placeholder, consisting of a rough-looking render of two Dart Monkeys.

• 13 new Achievements, all relating to Co-op, have been introduced, though they would all go unused until version 11.0:

• Respecing Monkey Knowledge now forces the game to save.
• Powers and Heroes no longer count against Achievements that require using specific tower classes, those being First Monkey First, War Monkeys, Abracadabmonkey, and Unsung Monkeys.

Version 5.1

• The 6th Military Monkey, the Mortar Monkey, has been released. A full set of text for this Monkey has existed in the game since launch, which has been updated to reflect alterations made to the tower's upgrades since.

Path	Tier	Launch	6.0+	Notes
3	4	All special Bloon properties are destroyed off each Bloon struck by the shattering shells.	Shattering shells strip all special bloon properties off all but the biggest bloons.	The description was changed in the final version to state that larger Bloons are unaffected, though it's not clear if this was a nerf or just added for clarity.

• Two new tracks have been introduced:
  • Moon Landing (intermediate)
  • Quad (expert)

The text for both Moon Landing and Quad has existed since launch.

• Three new Military Monkey Knowledge upgrades have been introduced:
  • Extra Burny Stuff
  • Budget Battery
  • Paint Stripper

Text and placeholder icons for all three of these Monkey Knowledge upgrades have existed since launch. The placeholder icons have been replaced in this update:

Launch	6.0+

• A new skin has been introduced for Gwendolin: Scientist Gwendolin.
• The description for the Decorated Hero Achievement has been changed to be more accurate:

Launch	6.0+
Get all medals for all Beginner maps	Get 36 difficulty medals on Beginner maps

• The background music for Dark Castle has been changed from Sunset Samba to Tribes and Tribulations.
• Balance changes and bug fixes, which can be viewed here.

Version 6.1

Released on 20 November 2018 exclusively for the iOS version. Fixes a frequent crash bug that only affected older devices, specifically those using an Apple A8 chip or earlier such as the iPhone 6, iPod Touch 6, and iPad Mini 3.

Version 7.0

Released on 12 December 2018 as a Christmas-themed update.

• The 7th Hero, Ezili, has been released. A preliminary icon and a full set of text for Ezili have existed in the game since launch, both of which have been updated to reflect alterations made to the Hero's design and upgrades since.

Launch	7.0+

• Ezili's original icon shows a few significant design changes: the pattern on her forehead was different, her eyebrows were square-ish instead of circular, her eyelids had small notches above them, and her hairstyle was different. Additionally, in the original icon, she was facing to the left, while in the updated icon, she's facing to the right.

Level	Launch	7.0+	Notes
5	Ezili's attack does far more damage to MOAB-Class Bloons.	Increased attack speed.	Swapped with level 8 in the final version.
8	Increased attack speed.	Ezili's attack does far more damage to MOAB-Class Bloons.	Swapped with level 5 in the final version.
20	MOAB Hex destroys MOAB-Class Bloons twice as fast.	MOAB Hex works faster and can destroy BAD Bloons.	The upgrade to MOAB Hex was nerfed to deal less damage over time, but was also changed to allow it to affect BADs. It's not known if MOAB Hex was originally able to affect BADs by default or not, making it unclear if this change is a buff or an accommodation to a MOAB Hex nerf at lower levels.

• Two new tracks have been introduced:
  • Alpine Run (beginner)
  • Peninsula (advanced)

The text for both Alpine Run and Peninsula has existed since launch.

• Races have been introduced.
  • Trophies have also been introduced, though they wouldn't serve a purpose until version 19.0.
• The game's app icon, main menu, and all tracks have been given a Christmas reskin.
• The holiday event-exclusive game mechanic returned.
  • In the case of Christmas, presents are the collectibles of choice, and the ability summons a sleigh to run over the track.
  • Due to negative feedback, this event system never returned after this update. All future holiday events would use the Collection Event system introduced for Easter in version 10.0.
• New options have been introduced for Advanced Challenges only: disabling selling, disabling Powers, and disabling Continues.
• Balance changes and bug fixes, which can be viewed here.

Version 7.1

Released on 13 December 2018. This was the first version released for Windows. Fixes a single oversight where ultra-widescreen devices would display the menu for Powers during Races, as Powers are supposed to be disabled in Races.

Version 8.0

Released on 31 January 2019.

• A new intermediate track has been introduced: KartsNDarts.
• Captain Churchill has received the new Sentai Churchill skin.
• Reverse mode now causes Bloons to spawn in reverse order for each round. For example, round 13 on Reverse mode will now spawn Green Bloons before Blue Bloons, rather than the other way around.
• MOAB-Class Bloons now use 3D models (first used in Bloons Adventure Time TD) rather than 2D images.
  • This change also applies to the Zombie MOABs and Zombie BFBs summoned by the Prince of Darkness.
• All abilities that generate cash, such as Supply Drop, now must undergo their full cooldown time after purchasing. All other abilities still only need to undergo 1/3rd of the full cooldown time before they can be used.
• Balance changes and bug fixes, which can be viewed here. The following balance changes went undocumented:
  • Total Transformation: Ability initial cooldown removed.

Version 8.1

Released on 8 February 2019.

• Several changes have been made specifically to the Windows version:
  • Key bindings can now be customised.
  • New key bindings have been added:
    • "Send Next Round (Races)" (Shift + Space by default)
    • "Activated Ability 1-12" (Number keys, -, and = by default)
    • "Send Test Bloon" (Ctrl + ~) by default) (Why the key bindings screen refers to the Ghost Bloon as the "Test Bloon" is unknown)
  • Some default key bindings have been changed:
    • "Send Bloon" hotkeys for Sandbox mode have been changed from Number keys, -, =, O, P, [, ], and \ to Ctrl + Number keys, Ctrl + O, Ctrl + P, Ctrl + [, Ctrl + ], and Ctrl + \.
    • The hotkeys for Powers have been changed from Number keys, -, =, [, and ] to Shift + Number keys, Shift + -, Shift + =, Shift + [, and Shift + ].
  • All three "Upgrade Path" hotkeys (<, >, and ? by default, as well as Numpad 1-3) can now upgrade the selected Hero, rather than just the first hotkey.
  • The "Change Targeting" hotkey (Tab by default) now works with the Mortar Monkey.
  • The Esc key (which cannot be rebound) no longer returns the player to the main menu from the game over screen.
  • UI elements that displayed text on "tap and hold", such as the abilities on the Heroes menu, now display on "hover" in this version.
• Bug fixes, which apply to all platforms.

Version 9.0

Released on 4 March 2019.

• The 8th Hero, Pat Fusty, has been released. A preliminary icon and a full set of text for Pat Fusty have existed in the game since launch, both of which have been updated to reflect alterations made to the Hero's design and upgrades since. This is the last Hero with data that has existed since launch.

Launch	9.0+

• Pat Fusty's original icon doesn't show many design changes, although he was originally in a completely different pose.
  • In the original, his arm appears to be glowing orange, which doesn't occur in the final game, but can be seen in concept art, which shows that it would've occurred when using his Rallying Roar ability.

Level	Launch	9.0+	Notes
10	Big Squeeze: Grabs a Bloon no bigger than BFB and crushes it to bits over 5 seconds.	Big Squeeze: Grabs a MOAB, BFB, DDT (if visible), or ZOMG and crushes it to bits over 5 seconds.	Big Squeeze now works on ZOMGs and DDTs at as soon as level 10 in the final version, instead of being unlocked at level 20.
20	Big Squeeze can affect ZOMG and DDT Bloon types.	Big Squeeze can grab several big Bloons at once.	Instead of allowing Big Squeeze to work on ZOMGs and DDTs (which it can do at as soon as level 10 in the final version), this upgrade allows the ability to grab multiple MOAB-Class Bloons at once in the final version.

• A new advanced track has been introduced: Pat's Pond.
• A new skin has been introduced for Striker Jones: Biker Bones (a reference to a community meme).

• The Challenge Editor has been introduced, allowing players to create and share their own challenges, as well as submit them as candidates for Daily Challenges or Advanced Challenges.
• Challenges now use fixed seeds for Apopalypse mode and Freeplay mode, which is generated based on the challenge's parameters.
• Sandbox mode has received two new tools: Reset Cooldowns and Reset Damage Counters.
• The icons for the MOAB-Class Bloons in Sandbox mode have been redone:

Launch	9.0+

• The original icons were likely placeholders that hadn't been accounted for until now, as they all reuse art from Bloons Monkey City (including the icon for the BAD, which was simply a recolor of the icon for Blastapopoulos).

• The difficulty of Freeplay mode has been increased slightly.
• The lanes on Muddy Puddles now alternate with a different pattern: 1 > 2 > 3 > 4 > 3 > 2 > repeat instead of 1 > 2 > 3 > 4 > repeat. This change, combined with all the balance changes made over every update up until now, finally made completing this track on CHIMPS mode possible, albeit barely.
• The damage counters and cash counters on towers now use 64-bit integers rather than 32-bit integers, effectively fixing an issue where damage counters would overflow into the negatives when going into Freeplay mode. However, bafflingly, the developers are still using signed integers instead of unsigned integers for these counters for some reason.
• For the Windows version, "multi-placement" now requires holding down the tower's hotkey instead of Shift.
• Balance changes and bug fixes, which can be viewed here. The following balance changes went undocumented:
  • Perma-Charge: Ability initial cooldown reduced (15 seconds -> 10 seconds).

Version 10.0

Released on 11 April 2019 as an Easter-themed update. The iOS version didn't receive the update until the day after due to issues with Apple's notoriously sluggish update approval process.

• A new intermediate track has been introduced: Spring Spring.
• A new skin has been introduced for Obyn Greenfoot: Ocean Guardian Obyn.
• The main menu and all tracks have been given an Easter reskin.
• A new holiday event has been introduced: the Collection Event, replacing the event system previously seen in versions 5.0 and 7.0. Completing tracks will award the player with a number of collectible items depending on the track difficulty and mode, and the player will be rewarded with random Insta-Monkeys for collecting enough each time.
  • In the case of Easter, eggs are the collectibles of choice.
• One new Achievement has been introduced:
  • Big Bloons: Pat likes hugging Big Bloons even more (hidden, requires winning 10 games using Pat Fusty)
• Big Bloons mode has been introduced, unlocked as a reward for completing the aforementioned new Achievement.
• The setting to toggle Double Cash (if purchased) has been moved to a new "extras" menu within the options menu, which is also the menu where Big Bloons mode is accessed if unlocked.
• Striker Jones' Artillery Command ability has a new animation.
• The Challenge Editor now allows the player to increase the health of Ceramic Bloons up to 2000% instead of only 1000%.
• Balance changes and bug fixes, which can be viewed here.

Version 10.1

Released on 16 April 2019. Consists of bug fixes.

Version 11.0

To do: Add a comparison between the early park path (which is a slightly modified version of its appearance in BTD5 Mobile) and the final park path. Some tracks have been altered in this update to better fit co-op, such as End of the Road.

Released on 3 July 2019 as a (belated) anniversary update.

• Co-op mode has been introduced.
  • All unused assets, text, and Achievements for Co-op that have existed in the game's data since version 5.0 are now used.

• The main menu and all tracks have been given an American Independence Day/Bastille Day reskin.
• A new Collection Event began.
  • In the case of American Independence Day, fireworks are the collectibles of choice.
• Sending rounds in Races now adds them to a queue, rather than each round being sent immediately. Each round is sent with a delay of 0.2 seconds.
• The difficulty of Freeplay mode has been increased significantly.
• New options have been introduced for Challenges: All Camo and All Regrow.
• Daily Chest rewards have been improved slightly.
• The setting to disable line of sight has been removed.
• The game's controls and input system have been substantially reworked:
  • Mortar Monkeys and Heli Pilots now have default targetting positions; the former is set to a short distance from the entrance of the track, while the latter only applies to Patrol mode and is set to two points in the middle of the track.
  • "Half-touch" mode has been introduced: tapping/clicking and holding on the selected tower will hide the upgrade panel while still showing their range, line of sight, and any target markers.
  • Tower placement is more precise.
    • When playing on a touchscreen, towers are less prone to "moving slightly" when letting go after dragging.
  • On the Windows version only, pressing Enter on certain menus, such as tutorial prompts, will act the same as clicking the on-screen button that progresses to the next menu.
  • On the Windows version only, hotkeys can now be used in Drag & Drop mode. Previously, they could only be used in Click & Drop mode for unknown reasons.
• Balance changes, bug fixes, and performance improvements, which can be viewed here.

Version 12.0

Released on 17 September 2019.

• The 4th Support Monkey, the Engineer Monkey, has been released. A full set of text for this Monkey has existed in the game since launch, and a preliminary icon has existed since version 11.0 (used for a "callout" in Co-op mode), both of which have been updated to reflect alterations made to the tower's design and upgrades since.

11.0	12.0+

Path	Tier	Launch	12.0+	Notes
1	5	Creates super-powerful sentries.	Creates super-powerful but highly unstable sentries.	Paragon Sentry was buffed so the sentries generate a powerful explosion upon expiring in the final version.
2	4	Overclock ability: Target Monkey becomes super powered for 60 seconds.	Overclock ability: Target Monkey becomes super powered for a short time.	The duration of Overclock was changed to depend on the cost of the tower in the final version (with more expensive towers having a shorter duration), rather than having a fixed duration of 60 seconds.
3	4	Bloon trap captures Bloons until full. Tap to empty full trap for cash.	Bloon trap captures Bloons until full. Select to empty full trap for cash.	The description for Bloon Trap was altered to account for non-touchscreen players (i.e. keyboard and mouse).
