For the BTD5 version of this upgrade, see Sprockets (BTD5).
Increases sentry gun and Engineer attack speed.
~ Official Bloons TD 6 description.

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.

Version History[]

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

[...] 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.
