Sprockets is the third upgrade of path 1 for the Engineer Monkey in Bloons TD 6. It allows the Engineer's nailgun and any newly spawned sentries to attack 66% faster. The Engineer's improved sentries are still deployed every 6.0s. Just as with normal sentries, sentries from Sprockets can gain crosspathing benefits from any Tier 1 crosspath and can gain bonus MOAB-class and Fortified damage from the Deconstruction crosspath. Starting from this upgrade and above, Sprockets sentries can inherit the pinning properties of Pin.

It costs $445 on Easy, $525 on Medium, $565 on Hard, and $630 on Impoppable.

Strategies

Summary

Sprockets primarily focuses on improving firepower via Engineer sentries. This makes the Sprockets Engineer a decent early-game advancement option in the game. Combining the Engineer's own range with his sentries, the Sprockets Engineer has rather good overall combined range and DPS for its price.

Tips

• Adding Sprockets can allow the whole Engineer and his sentries to easily solo versus rounds with lots of Yellows and/or Pinks, where normally other sentry-based Engineers would struggle.
• Generally, the 3-0-2 crosspath is better than the 3-2-0 crosspath. The Pin helps the Engineer, while the Oversize Nails increases pierce. Plus, sentries can now pin bloons starting from 3-0-2.
  • Larger Service Area can be bad because it increases sentry deploy range, however Deconstruction helps damage MOABs and Fortified Bloons easier.

Version History

Most problems with Sprockets were addressed with its earlier upgrades, thereby buffing the value of Sprockets in return.

15.0

• Standard Sentry pierce increased from 1 to 2.

• Sprockets sentries are deployed faster (7s → 6s).

23.0

• Sprockets is now affected by crosspathing from Deconstruction.

26.0

“	[...] 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.	”
	~ Ninja Kiwi

• 3-0-2 Sentries & Higher will now also be able to Pin Bloons they pop
