Sprockets is the Engineer Monkey's path 1 tier 3 upgrade in Bloons TD 6. It halves the cooldown of the Engineer Monkey's and sentries' attacks, effectively doubling their attack speed. It does not improve the speed at which the Engineer deploys its sentries. Additionally, sentries with Sprockets gain the ability to stun Bloons when crosspathed with Pin.

Strategy

This strategy section is empty or incomplete. See the strategy guidelines for more information on how to write strategy sections. The editor who added this notice elaborates: What about 3-0-0 use cases with lots of blimp debuffs? Like CT Bosses? Also maybe mention more strategy of Sprockets, also compare it to 2-0-3 perhaps?

This section was last updated for: version 52.2

Sprockets is an early game tower that has a steeper cost than Double Gun but trades it for higher DPS in its sentries. Like the rest of the top path, it's weak before placing all its sentries, and can do bad sentry placements due to RNG.

3-2-0 is better for building into Sentry Champion, having better single-target damage. 3-0-2 is better for the early game, stopping groups of Bloons, and more effective at the role than 2-0-3 due to sentry pins.

Version 15.0

•  Sentry: pierce increased ― 1 → 2

Version 17.0

•  Sentry: No longer gains Camo detection after loading a save (bug fix)
•  Sentry spawner: No longer ignores smart placement if the Engineer Monkey cannot reach the track (bug fix)

Version 20.0

“

Continuing our efforts to make crosspaths meaningful and fit the style of each path more solidly, a number of crosspath and base level balance shifts were made.
— Update notes

”

•  Sentry: deployment rate increased ― 7s → 6s

3-1-0, 3-2-0

•  Larger Service Area crosspath now increases Sentry range by +4

3-0-1, 3-0-2

•  Oversize Nails crosspath now allows Sentries to pop frozen Bloons
•  Oversize Nails crosspath now increases Sentry pierce by 1

Version 23.0

3-2-0

•  Deconstruction: now grants all Sentries +1 damage to Fortified & MOAB

Version 26.0

“

Additionally higher tier sentries will now be able to benefit from the xx2 Pin crosspath, so enjoy some laser pins.
— Update notes

”

3-0-2

•  Pin now allows Sentries from Sprockets and above to pin Bloons

Version 29.0

“

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
— Update notes

”

•  Upgrade cost increased ― $525 → $575
  •  Overall cost is unchanged (due to cost changes for previous tiers)

Version 33.0

“

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.
— Update notes

”

•  Nailgun: Attack cooldown reduced ― 0.42s → 0.35s (attack speed increased by 20%)
•  Sprockets buff amount to sentry rate increased ― 60%s → 50%s
  • Note: Attack cooldown of sentry decreased from 0.57s to 0.475s

3-2-0

•  Sentry: Deconstruction's bonus damage to MOAB-Class Bloons and Fortified Bloons are no longer mutually exclusive

Version 43.0

“

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.
— Update notes

”

•  Overall cost reduced by $50 (due to cost changes for previous tiers)
•  Sentry deployment: Sentries now spawn within 20% of their range to the track

Version 47.0

“

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

”

•  Overclock and Ultraboost abilities no longer target Engineer sentries

Version 48.0

“

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.
— Update notes

”

•  Sentry deploy: Attack cooldown reduced ― 6s → 5s
