— Update notes
Tiers Changes
1-1-0 Sentry Gun + Larger Service Area and further upgrades
  •   Larger Service Area crosspath now increases Sentry range by +4
1-0-1 Sentry Gun + Oversize Nails and further upgrades
  •   Oversize Nails crosspath now allows Sentries to pop frozen Bloons

Engineer is quite poor in terms of crosspathing, so we’ve added crosspath benefits to Cleansing Foam as well as an overall price buff to the middle crosspathing upgrades. 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.

Tiers Changes
5-X-X Sentry Paragon
  •   Sentry Paragon explosion damage increased ― 85 → 100
X-1-X Larger Service Area
  •   Upgrade cost reduced ― $550 → $250
X-2-X Deconstruction
  •   Upgrade cost increased ― $200 → $350
0-3-1 Cleansing Foam + Oversize Nails and further upgrades
  •   Oversize Nails increases Cleansing Foam pierce ― 10 → 15
X-4-X Overclock
  •   Overclock duration formula has been reworked to apply on a tier by tier basis rather than just lasting for a shorter duration based on the cost of the tower.
    • Note: Overclock used on T3 duration remains the same at 100% (60s)
    •   Overclock used on T5 duration reduced ― 60s → 30s
    •   Overclock used on T4 duration reduced ― 60s → 45s
    •   Overclock used on T2 duration increased ― 60s → 75s
    •   Overclock used on T1 duration increased ― 60s → 90s
    •   Overclock used on T0 duration increased ― 60s → 105s
    •   Overclock used on Hero duration based on Hero tier : Hero level / 4, e.g. Level 8 is equivalent to T2 duration
      • Note: Hero tier starts at level 0 rather than 1
Some big buffs to Bloon Trap so it can now be used more effectively
— Update notes
Tiers Changes
X-X-4 Bloon Trap
X-X-5 XXXL Trap
  •   Can now spawn multiple traps per round, at a cooldown of 20 seconds for a new trap
Sentry Expert has underperformed for a while, so we’re adding solid crosspathing buffs to all Sentries. We’ve added a pierce & speed boost to Overclock’s base upgrade and lowered the cooldown on Ultraboost to allow the possibility for it to achieve full uptime as a freeplay tower and get its stacks up faster. Finally last update we allowed Bloontrap to be set multiple times per round, and we wanted to stay on the side of caution with a long cooldown, but after seeing it in the wild we are happy to make this cooldown faster.
— Update notes
Tiers Changes
4-0-1 Sentry Expert + Oversize Nails
  •   Oversize Nails increases Sentry pierce by roughly 25% instead of +1
    •   Crushing Sentry: pierce increased ― 22 → 28
    •   Bomb Sentry: pierce increased ― 30 → 38
    •   Cold Sentry: pierce increased ― 15 → 19
1-2-0 Deconstruction + Sentry Gun and further upgrades
  •   Deconstruction: now grants all Sentries +1 damage to Fortified & MOAB
X-4-X Overclock
  •   Pierce increased ― 3 → 15
X-4-X Overclock and further upgrades
  •   Projectile speed increased ― 375 → 750

  •   Pierce increased ― 3 → 30
  •   Ultraboost: ability cooldown reduced ― 45s → 35s
  •   Ultraboost: initial cooldown reduced ― 15s → 5s (undocumented)
X-X-4 Bloon Trap
  •   Bloon Trap: trap cooldown reduced ― 20s → 15s
2-0-4 Bloon Trap + Faster Engineering
2-0-5 XXXL Trap + Faster Engineering
  •   Faster Engineering: rate buff to Bloon Traps increased ― 0.8× → 0.6×
Engineer XXL trap is extremely powerful but too expensive for backline dps and we’d like to see it more viable for frontline engineer builds
— Update notes
Tiers Changes
X-X-5 XXXL Trap
  •   Upgrade cost reduced ― $60,000 → $54,000
It has been clear that Sentry Expert needs changes, with Cryo sentries the only ones that really seemed valuable and purposeful, so all of the others have been improved to fit their role. Additionally higher tier sentries will now be able to benefit from the xx2 Pin crosspath, so enjoy some laser pins. Bloon Trap redeployment rate has also been buffed a fair amount.
— Update notes
Tiers Changes
3-0-2 Sprockets + Pin and further upgrades
  •   Sentries: Now can pin Bloons
4-X-X Sentry Expert
  •   Laser Sentry: pierce increased ― 4 → 8
  •   Crushing Sentry: damage increased ― 1 → 2
  •   Crushing Sentry: attack cooldown increased ― 1s → 1.1s
  •   Boom Sentry:attack cooldown decreased ― 1.3s → 0.9s
4-0-1 Sentry Expert + Oversize Nails
  •   Laser Sentry: pierce increased ― 5 → 10
    • Note: Pierce bonus increased from +1 to +2
X-X-4 Bloon Trap
  •   Redeployment cooldown reduced ― 15s → 12s
    • Note: 204 cooldown reduced from 9s to 7.2s
Tiers Changes
X-4-X Overclock
  • Ability: No longer causes framerate issues if linked to a Tech Bot without a target assigned (bug fix)
Alright, Sentry Paragon is now a Champion
— Update notes
Tiers Changes
5-X-X Sentry Champion
  •   Name changed ― "Sentry Paragon" → "Sentry Champion"
Engineer’s bottom 2 paths have a heavier support focus, so to start them off a bit easier we have shifted some starting cost out and into the non-supportive path. For the sake of further improved crosspath potential, we have also re-envisioned the ‘Larger Service’ crosspath as giving smarter service as well in the form for targeting for Bloontrap & Cleansing Foam
— Update notes
Tiers Changes
0-0-0 base tower
  •   Cost reduced ― $450 → $400
3-X-X Sprockets
  •   Upgrade cost increased ― $525 → $575
X-3-X Cleansing Foam and further upgrades
  •   Foam: Manual targeting option added
0-1-4 Bloon Trap + Larger Service Area and further upgrades
  •   Trap: Manual targeting option added
To add a bit of quality of life solving problems with trap needing to fill once before moving to target location, Bloontraps placed off-track never being able to fill, and maybe even to just add some interesting micro, any Bloontraps will now become expired after a short delay when their Engineer has a new target set.
— Update notes
Tiers Changes
X-3-X Cleansing Foam and further upgrades
  •   Foam: Should now count damage when popping lead bloons (bug fix)
0-1-4 Bloon Trap + Larger Service Area and further upgrades
  •   Trap: Picking new target expires current Bloontrap & places new one
Sentry Expert really needed some logic fixes to get more of the actual correct sentries placed at the right times, it has also received a number of power buffs across the board to the special sentries at T4 complimenting the new logic reworking. Cleansing Foam has had some extra crosspath utility added at the cost of a small price increase and a large decrease to Ultraboost price.
— Update notes
Tiers Changes
4-X-X Sentry Expert
  •   Sentry Expert logic has been reworked to evaluate threat levels based on Bloon types that it can counter, Bloon types that counter the sentries that it wants to spawn, and which of the current threats on screen is the greatest. Distribution of sentry types should scale based on how much one Bloon threat is more of a threat than another.
  •   Crush Sentry: Ceramic damage bonus increased ― +1 → +4
  •   Crush Sentry:Damage type changed ― Sharp → Shatter
  •   Bomb Sentry: Damage increased ― 2 → 4
  •   Cold Sentry: Pierce increased ― 15 → 25
  •   Cold Sentry: Explosion radius increased ― 12 → 18
  •   Energy Sentry: Gains increased MOAB-class damage ― +0 → +2
X-3-X Cleansing Foam
  •   Upgrade cost increased ― $800 → $850
1-3-0 Cleansing Foam + Sentry Gun and further upgrades
  •   Foam makes Sentries shoot Foamy nails that strip properties
0-3-2 Cleansing Foam + Pin and further upgrades
  •   Pin crosspath allows Cleansing Foam to slow Bloons by 50% for 2 seconds
  •   Pin crosspath allows Cleansing Foam to slow all MOAB-class (including BADs) by 50% for 2 seconds (bug)
X-5-X Ultraboost
  •   Upgrade cost reduced ― $120,000 → $105,000
X-X-4 Bloon Trap
  •   Bloon Trap issue resolved on Sunken Columns with Bloontraps falling under the map in certain location (bug fix)
0-1-4 Bloon Trap + Larger Service Area
  •   Bloon Trap issue resolved with certain conditions causing Bloontraps to repeatedly auto-collect even while empty (bug fix)
032 Engineer Cleansing Foam now works correctly on all MOAB Class targets - hope you enjoyed that temporary treat
— Update notes
Tiers Changes
0-3-2 Cleansing Foam + Pin and further upgrades
  •   Cleansing Foam: no longer slows MOAB-class bloons (including BADs) with Pin crosspath (bug fix)
Tiers Changes
0-3-2 Cleansing Foam + Pin and further upgrades
  •   Cleansing Foam slow stacks on a single target (bug)
Tiers Changes
0-3-2 Cleansing Foam + Pin
0-4-2 Overclock + Pin
0-5-2 Ultraboost + Pin
  •   Foam slow effect no longer stacks on a single target (bug fix)
X-5-X Ultraboost
  •   Ability: now limited to 3 uses per round
Paragon
  • Resolved an issue where the Master Builder’s Sentry ability would not snap placement to your next tap on mobile (bug fix)
The MOAB offense of top path lacks for a mainly dps tower that is quite complex to use, T3 Sprockets already feels underwhelming so is seeing a buff here carrying up to T4, and the 320 crosspath will now be able to double dip on the Fortified & MOAB damage bonuses that it gains. Cleansing Foam is only seeing a slight tweak to help it be more viable if you want to attempt it as 'main camo detection’, and this mainly fixes some issues in ABR games allowing it to catch quick initial camo spawns.

Tiers Changes
3-X-X Sprockets
  •   Sprockets buff amount to sentry rate increased ― 60%s → 50%s
    • Note: Attack cooldown of sentry decreased from 0.57s to 0.475s
3-X-X Sprockets
4-X-X Sentry Expert
  •   Nailgun: Attack cooldown reduced ― 0.42s → 0.35s (attack speed increased by 20%)
5-X-X Sentry Champion
  •   Nailgun: Attack cooldown reduced ― 0.42s → 0.3s (attack speed increased by 40%)
1-2-0 Deconstruction + Sentry Gun and further upgrades
  •   Sentry: Deconstruction's bonus damage to MOAB-Class Bloons and Fortified Bloons are no longer mutually exclusive
X-3-X Cleansing Foam and further upgrades
  •   All attacks: Now gains 1s of 4x rate on round start
Overclock's considerable longer duration benefit on lower tiers currently serves little purpose and only leads to weirdness in upgrading boosted towers, so for now we’d rather minimize this on the early cases that don’t serve much purpose .
— Update notes
Tiers Changes
X-4-X Overclock
X-5-X Ultraboost
  •   Ability: no longer has a 1.75× duration bonus for tier 0 towers
  •   Ability: no longer has a 1.5× duration bonus for tier 1 towers
  •   Ability: no longer has a 1.25× duration bonus for tier 2 towers
  •   Ability: Lasts 60s on heroes regardless of level (undocumented)
Sentry Champion’s pierce crosspath does not feel like it has enough of an edge to compete with the deconstruction crosspath.
— Update notes
Tiers Changes
5-0-1 Sentry Champion + Oversize Nails
5-0-2 Sentry Champion + Pin
  •   Turret pierce increased ― 6 → 7
X-5-X Ultraboost
  •   Upgrade cost reduced ― $105,000 → $72,000
XXXL Trap 205 crosspath hasn’t actually ‘been working’ due to the base attack rate being faster than minimum deployment delay so we have slowed the base rate to make 205 crosspath actually matter. Along with this, since the fortification bonus aspect of x2x hasn’t ever done anything for Bloontraps, 024 will now ignore the fortification of Bloons that it eats
— Update notes
Tiers Changes
0-2-4 Bloon Trap + Deconstruction
0-2-5 XXXL Trap + Deconstruction
  •   Deconstruction crosspath grants Bloontraps the ability to de-fortify anything it consumes prior to capturing
X-X-5 XXXL Trap
  •   Bloontrap deploy rate reduced ― 2.8s → 5.8s
2-0-5 XXXL Trap + Faster Engineering
  •   Faster Engineering crosspath 'should now work' and actually make Bloontrap’s cooldown faster
  •   Bloontrap deploy rate reduced ― 2.8s → 3.48s
The 005 crosspath fix in the last update left XXXL Trap slower than previously even if crosspathed to 205, so we are increasing that base 005 slightly to match up the 205 crosspath again so that it isn’t any slower than before.
— Update notes
Tiers Changes
X-X-5 XXXL Trap
  •   XXXL Trap: attack cooldown reduced ― 5.8s → 4.6s
    • Note: 205 decreased from 3.48s to 2.76s attack rate. Effectively 2.8s due to minimum trap delay
Paragon
  •   Resolved an issue where the Paragon’s permanent speed boost per round would not load until the end of the first round played after loading a save (bug fix)
  •   Engineer Paragon should no longer throw sentries into the middle of the map due to techbots (bug fix)
Tiers Changes
Paragon
  •   Engineer Paragon no longer defaults to throwing out a Green Sentry after loading a save (bug fix)
  •   Engineer Paragon sentries are now correctly destroyed if their platform is removed (bug fix)
  •   Engineer Paragon sentries no longer position incorrectly when placed as the round ends (bug fix)
Applying pierce crosspathing to Sentry Champion only granting an abysmal +1 pierce to the explosion while an intended joke at the time still feels a little silly, we’re separating that up to get its own larger increase now. Some extra of a makeup buff for XXXL, while the crosspathing rework itself feels nice it ended up nerfing the high-level micro play of this upgrade far more than intended.
— Update notes
Tiers Changes
5-0-1 Sentry Champion + Oversize Nails
5-0-2 Sentry Champion + Pin
  •   Sentry Explosion: Crosspath benefit to pierce bonus increased ― +1 → +21
    • Note: Pierce increased from 51 to 70
X-X-5 XXXL Trap
  •   Upgrade cost reduced ― $54,000 → $48,000
No changes here as well, we know some people are still hoping for a redesign in general, but with everything else about paragons uncertain this was not a good time for that. We also want to have another Paragon in the support category dealing a DPS role before we seriously consider taking away the current only dps in that category which is already well balanced with strong competitive use.
— Update notes
Tiers Changes
Paragon
  •   Has less Boss damage, especially on Elite and at higher Degrees
  •   Cost per power increased ― $25 → $27.625/$32.5/$35.1/$39
Tiers Changes
4-1-0 Sentry Expert + Larger Service Area
  •   Engineer 410 should no longer 'Pin' Bloons after loading a save (bug fix)
Improvements for Sentry Expert AI based on your feedback.
— Update notes
Tiers Changes
4-X-X Sentry Expert
  •   Sentry Expert should react with less Cold Sentries in response to Pink Bloons, and prioritize a more for AoE cleanup
  •    Sentry Expert should react with less Energy sentries in response to Blue MOABs, and prioritize a more for ceramic cleanup
X-5-X Ultraboost
  •    Ultraboost cleansing foam pierce ― 10 → 30
  •    Ultraboost ability now has full duration on T4s ― 0.75x → 1x
  •    Ultraboost ability now has full duration on T5s ― 0.5x → 1x
X-X-4 Bloon Trap
X-X-5 XXXL Trap
  •   Bloontrap now divides the base value of absorbed Bloons between all players when collected, any extra multiplied value is fully granted to the owner of the Bloontrap
    • Note: Overall buff for co-operative gameplay, a nerf to the Bloon Trap user
While better than many options, base Engineer still takes a lot of available starting cash so the cost is reduced slightly and being moved back up into Cleansing Foam & Bloontrap; also with a reduction to Double Gun’s price to reflect the lower value of the base tower. Sentry placements are slightly changing to improve their reliability, and will now spawn closer to the track depending on how much range the sentry has. Sentry Champion, while strong with them, is lacking without high buff support so we’re trying out an increase to the sentry damage on it.
— Update notes
Tiers Changes
0-0-0 base tower
  •   Cost reduced ― $400 → $350
1-X-X Sentry Gun and further upgrades
  •   Sentry deployment: Sentries now spawn within 20% of their range to the track
5-X-X Sentry Champion
  •   Champion Sentry: Damage increased ― 2 → 3
X-3-X Cleansing Foam
  •   Upgrade cost increased ― $850 → $900
X-4-X Overclock
  •   Foam: Pierce increased ― 10 → 15
    • Note: Ultraboost foam pierce unchanged (30)
X-X-3 Double Gun
  •   Upgrade cost reduced ― $500 → $450
X-X-4 Bloon Trap
  •   Upgrade cost increased ― $3,500 → $3,600
  • "Placing a Master Builder turret at the very bottom of the screen should no longer crash"
The Ultraboost ability is now starting on cooldown to put a limit on buy’n’resell issues, but this is to ease up on the use per round limit which was causing frustration. We felt the Master Builder's perma-buff-per-round wasn’t valuable enough to make use of building in advance, so we are reducing the base attack speed with increased power in return to more heavily improve the maximum scaled power from this.
— Update notes
Tiers Changes
X-5-X Ultraboost
  •   Ability: now starts with its full cooldown instead of carrying over Overclock's cooldown
  •   Ability: max uses per round increased ― 3 → 10
Paragon
  •   Attack speed bonus per round increased ― 10% → 30%
  •   Minimum attack cooldown increased ― 0.05s → 0.15s
  •   Nail gun: cooldown increased ― 0.3s → 1s
  •   Nail gun: damage increased ― 100 → 300
  •   Nail gun: bonus damage to bosses increased ― +100 → +500
  •   Nail gun: stun duration increased ― 1s → 5s
  •   Green Sentry Paragon: targeting can now be changed to Locked
Now that Ultraboost has an initial cooldown we are again allowing it to be used between rounds. Middle crosspath feels too good for Bloontraps because of the massive quality of life it brings, so we’re pushing the DPS more for top crosspath by allowing Double Gun to also double the projectiles of Sentries. The expensive XXL Trap's cash generation comes in too late given Bloontraps fall off as an income generator in the late game, so we’re reducing the upgrade cost and increasing the cash generation that it brings.
— Update notes
Tiers Changes
X-5-X Ultraboost
  •   Ultraboost ability: can now be activated during the break between rounds
1-0-3 Double Gun + Sentry Gun and further upgrades
  •   Double Gun Sentries now shoot two projectiles at once
X-X-4 Bloon Trap
X-X-5 XXXL Trap
  •   Trap: Disappears when the Engineer is sold or sacrificed. No cash will be collected from the trap. (bug)
    • Note: This behavior is intended for Tier 5 but not for Tier 4
X-X-5 XXXL Trap
  •   Upgrade cost reduced ― $48,000 → $45,000
  •   Trap: cash per Bloon captured increased ― ×2 → ×3
Tiers Changes
1-0-3 Double Gun + Sentry Gun and further upgrades
  •   Sentry: Double Guns upgrade no longer reduces their pierce ― 2 → 3 (bug fix)
This was becoming annoying screen clutter with large numbers of sentries, and feels unnecessary when you can overclock the engineer itself to create more sentries instead.
— Update notes
Tiers Changes
1-X-X Sentry Gun and further upgrades
X-4-X Overclock
X-5-X Ultraboost
  •   Overclock and Ultraboost abilities no longer target Engineer sentries

0-1-4 Bloon Trap + Larger Service Area and further upgrades
  •   Bloontrap cooldown should no longer break depending on upgrade order (bug fix)
    • Note: Larger Service Area no longer bypasses minimum trap delay (2.8s)
Really only one major change here; a rebalancing to how the 2xx Crosspath applies across various engineer upgrades, and some base stats being changed to accommodate fitting this.

  •   Trap: Replacement delay reduced ― 2.8s → 1.4s
Paragon
  •   Resolved an issue where Sentry Paragon explosions would forget their Support categorization after loading a save (bug fix)
We may return to this again later, but for now due to the clear desire for more Paragon synergy options the Engineer Paragon is trading in some of its main attack damage in exchange for a new AoE Overclock ability
— Update notes
Tiers Changes
1-X-X Sentry Gun
  •   Description changed ― Creates temporary sentry guns and deploys them nearby. → Creates temporary sentry guns and deploys them close to track anywhere in radius.
Paragon
  •   Nail gun attack: Bonus damage to Bosses reduced ― +500 → +300
  •   Gains the Power Glove ability that can overclock Paragons and all other towers in a small area
  •   Description changed ― Monkey engineering developed to perfection. Creates three Mega Sentries that can build their own sentries. → Monkey engineering developed to perfection. Can Overclock other Paragons, and creates three Mega Sentries that can build their own sentries.
Tiers Changes
Paragon
  •   Power Glove ability: effects now persist between saves
  •   Sub Towers from Paragons should now correctly be stunned when the main tower is
Overclock’s Village range bonus always felt like an odd special case, and now that there is a proper dedicated range bonus ability the combined range this grants for villages ended up being overpowered, after consideration we didn’t want to jump straight to deleting the ultraboost stacking tech here but have lowered the range bonuses from Overclock.

Tiers Changes
4-2-0 Sentry Expert + Deconstruction
  •   Energy Sentry: Bonus damage to MOAB-Class Bloons increased ― +2 → +3 (bug fix)
X-4-X Overclock and further upgrades
  •   Overclock ability: Range bonus on Monkey Villages decreased ― +25% → +10%
    • Note: Also affects the temporary Ultraboost effect. Does not affect Paragon's Power Glove (+25%)
X-5-X Ultraboost
  •   Ultraboost ability: Range bonus on Monkey Villages per stack decreased ― +2.5% → +1.5%
Paragon
  •   Cannot longer be targeted with another Engineer’s Overclock (bug fix)
Engineer Paragon is no longer balanced due to its new ability, so we’re adjusting its base attack rate and range to bring it a little more back in line

Tiers Changes
Paragon
  •   Main attack: Attack cooldown increased ― 1s → 1.5s (attack speed reduced by 33.33%)
  •   Range decreased ― 70 → 60
    • Note: Mega Sentries and Modified Paragon Sentries unchanged (70 and 50)
Engi Paragon is too good across the board since the addition of its Overclock ability, we’re moving the Village Range buff in line with the normal overclock, and nerfing its ability cooldown so that higher degrees are required to keep a high uptime buffing other paragons. Since the AoE overclock is unique to the Engineer Paragon and not aimed at other Paragons that part of the ability is instead being improved on.

  • Engineer Paragon’s changes has some issues, so clearing this up for now
    • Duration is set to 60s
    • Tiers 1-5 receive a duration multiplier of 1x
    • Paragons receive a duration multiplier of 0.25x
    • The AoE duration will now also last 60s instead of 30s, not intended but we will be leaving this in as is for now

Engineer Paragon's power glove pairs up much too well with some paragons compared to others so we’re trying out a shift to lower cooldown but also lower duration to break this up.

[While talking about Wizard Paragon changes] Since its addition this synergy has been a problem for Paragon balance, so we’re implementing a special-case to make Overclock less effective on the Wizard Paragon; this allows us to buff that lost power back into the Powerglove Overclock. Since these changes are "magically" linked, we’re mentioning the Engineer buff here too—also to cast Confusion on anyone who skips this section and only reads the Engineer notes!

[...] Overclock’s duration on level 20 heroes has been excessive; we’re cutting the jank and standardizing to a consistent 30s duration for heroes, with Ultraboost still providing the full 60s.

X-4-X Overclock
  •   Overclock: Buff duration on Heroes decreased at all levels ― 60s → 30s
    • Note: Ultraboost temporary buff unaffected (60s)
X-1-4 Bloon Trap + Larger Service Area and further upgrades
  •   Bloon Trap now correctly moves on target point set after loading a save (bug fix)
X-X-5 XXXL Trap
  •   XXXL Trap should now count cash generated correctly (bug fix)
Paragon
  •   Power Glove: Buff duration on Paragons increased ― 9s → 15s
    • Note: Duration percentage increased from 15% to 25%
Oh yea we have one more tower balance change. As the Engineer paragon moves to a more supportive role, we are toning down the direct boss damage and attack speed but also lowering the upgrade cost.
