=== [[Freeplay]] ===

{{BTD6 changes

| version = 21.0

| changes = *Stats summary now displays upon Game Over in freeplay

| names = Freeplay

}}

=== Buff Icons ===

* A rather massive behind the scenes overhaul of the Buff Icons system, and they will also not clip out the edges of the map anymore.

=== [[Insta Monkey]] ===

{{BTD6 changes

| version = 21.0

| quote = The Insta-monkey system in BTD6 has evolved a lot since launch, from a farmable mechanic to grant easier wins into more of a collection system. With this, we have found that while the initial intention was to give a nice beefy reward for any win, this has resulted in Tier 3 and 4 insta-monkeys being far too common while Tiers 0-2 are much more coveted with no farmable way to get them. We have decided to work on this by redefining the free reward earned on round 100, instead of being a random chance of Tier 3 or 4 rewards will now follow this logic

| changes = *Beginner maps: Insta reward range Tier 0 to Tier 2

*Intermediate maps: Insta reward range Tier 1 to Tier 3

*Advanced maps: Insta reward range Tier 2 to Tier 4

*Expert maps: Insta reward range Tier 3 to Tier 4

*Round 200 and higher remains at the past Tier 3 to Tier 4 regardless of difficulty

| names = Insta Monkey; Map

}}{{Quote|Following up on the changes in 20.0 in relation to making for smaller and faster updates, additional changes have been made to more efficiently and correctly clean up old bundles when updating before downloading new & changed files}}

* Added Hover/Tap and hold state to all medals on the stats screen

* Odyssey Menu now supports the display of a seasonal theme

* Added in a ‘Loop’ option to the Jukebox for current song

* After having had a name set at least once before, Monkey Names can now be edited from the Player profile page

* Added Search Functionality to the Achievements menu

* Hidden Achievements now appear in the Achievements menu and display progress before being completely unlocked. Description & title will remain hidden until the achievement is earned. You can find these by searching for ‘???’

=== Desktop version ===

* Added a new options toggle to disable the precision ‘Nudge Mode’. With this disabled towers will always snap to where you click during placement

* Your ‘Placement Mode’ is now saved locally per device rather than in your player save

* In addition to ESC acting as a general hybrid back/pause button, the Tilde/Backquote key (~) will now act as an instant uninterruptible pause (unless you lose) that will only open the pause menu, not close it. As with all hotkeys this can be remapped from the options in the main menu.

* Scrolling with the mouse wheel will now move at the correct speed on scroll-able menus that go from side-to-side

* Uninstallation on steam will now open an additional prompt to remove all login information from your machine as well

*{{nerf|Arctic Wind no longer inconsistently slows one of two Zebra children after popping a rainbow|fix=y}}

| quote 1 = While Icicles is quite fun for midgame cleanup, we acknowledge points raised on Cryo Cannon trading off it’s freeze prowess too quickly when the smaller freeze area even with such a fast rate increase still overall makes it struggle to slow as effectively. To counter this a little we have doubled the freeze radius of Cryo Cannon, but also increased damage of both the Ice Balls & Icicles to highlight more the intention of this path swapping to a damage hybrid earlier.

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. Due to overall comparisons between Downdraft’s blowback & MOAB Shove we have also slashed MOAB Shove’s price by 30% to give it & Comanche more of a kickstart

We like choices not requirements so to counter this we have made Burny Stuff scale with top-path damage & shifted a small amount of the speed from Faster Reload onto the base mortar and reduced base accuracy considerably.

We wanted to cover all of the usability issues with this upgrade while also powering it up and expanding more on the mechanic that makes it so unique. We hope this will be enough to make Wizard very useful in a number of ways, but will be keeping a watchful eye on how it plays out.

**{{buff|With 1-X-X crosspath: 47 units → 70.5 units}}

| quote 1 = While Sticky Bomb still has issues we are investigating, this damage buff allows Sticky Bombs to destroy all regular MOABs from round 81 to 100 in a single bomb in standard games whether they are fortified or not. In addition since this damage runs off a timed function, somewhat similar to Alchemist’s Unstable Concoction, we felt that adding a range increase to the Sticky attack similar to Concoction should give a better chance to actually explode before the target MOAB is destroyed by other towers.

+| version = 21.0
+| quote = The Insta-monkey system in BTD6 has evolved a lot since launch, from a farmable mechanic to grant easier wins into more of a collection system. With this, we have found that while the initial intention was to give a nice beefy reward for any win, this has resulted in Tier 3 and 4 insta-monkeys being far too common while Tiers 0-2 are much more coveted with no farmable way to get them. We have decided to work on this by redefining the free reward earned on round 100, instead of being a random chance of Tier 3 or 4 rewards will now follow this logic
+| changes = *Beginner maps: Insta reward range Tier 0 to Tier 2
+*Intermediate maps: Insta reward range Tier 1 to Tier 3

+* Added Hover/Tap and hold state to all medals on the stats screen
+* Odyssey Menu now supports the display of a seasonal theme
+* Added in a ‘Loop’ option to the Jukebox for current song
+* After having had a name set at least once before, Monkey Names can now be edited from the Player profile page
+* Added Search Functionality to the Achievements menu
+* Hidden Achievements now appear in the Achievements menu and display progress before being completely unlocked. Description & title will remain hidden until the achievement is earned. You can find these by searching for ‘???’
+=== Desktop version ===
+* Added a new options toggle to disable the precision ‘Nudge Mode’. With this disabled towers will always snap to where you click during placement
+* Your ‘Placement Mode’ is now saved locally per device rather than in your player save
+* In addition to ESC acting as a general hybrid back/pause button, the Tilde/Backquote key (~) will now act as an instant uninterruptible pause (unless you lose) that will only open the pause menu, not close it. As with all hotkeys this can be remapped from the options in the main menu.

We’ve been somewhat unhappy with how Overclock sits in the game for a while and especially how the interaction with tower cost causes levelling heroes naturally to be far advantageous over purchasing upgrades when this is already underused. We have made an attempt to rework these issues by moving it to a tier-based system rather than price.

+| quote = Churchill is a chunky, expensive & slow levelling powerful hero, when he was launched he fit well in this spot but his synergies have not aged well. We have started with a small XP adjustment and greatly improved the power of his MOAB Barrage
+|xp curve before=1.8
+|xp curve after=1.71
+| changes 1 = *{{buff|MOAB Barrage: damage increased|100|200}}

+{{BTD6 hero changes
+| version = 21.0
+| hero = Ezili
+| quote = It felt fitting for so many reasons right now, but in addition to Unpopped Army buffs Ezili will now offer them a large pierce boost who then in turn offer up an improved cleanup tower to assist Ezili in dealing with with her main weakness
+| changes 1 = *{{buff|Now increases the pierce of all Zombie Bloons summoned by +50%}}

+{{BTD6 hero changes
+| version = 21.0

+| quote = We feel that applying the entire recent Roar nerf right away from level 3 was a mistake. To alleviate the impact here we have increased the level 3 duration to a little more than it was
+| changes 1 = *{{buff|Rallying Roar buff duration increased|5s|8s|note=Level 14+ unchanged}}
+| changes 1 levels = 3–13
+}}
+===[[Adora (BTD6)|Adora]]===
+{{BTD6 hero changes
+| version = 21.0

+| quote = Keeping in line with our “Slow” hero XP curve, Adora’s XP requirement will be reduced to match the new curve applied on Churchill

+===[[Etienne (BTD6)|Etienne]]===
