Faster Engineering

Increased efficiency allows the Engineer to produce sentries, foam and bloon traps more often.

Faster Engineering is the Engineer Monkey's path 1 tier 2 upgrade in Bloons TD 6. This upgrade reduces the cooldown of the Engineer Monkey's sentry-spawner attack from 10 seconds to 5 seconds, increasing its production rate by 100%. If crosspathed with Cleansing Foam, it reduces the foam gun cooldown by 50%. If crosspathed with Bloon Trap, it reduces the time it takes for the Engineer Monkey to stockpile a new trap by 50%, and reduces the replacement delay by 0.7 seconds from the base amount.

This section was last updated for: version 51.2

Faster Engineering is an effective crosspath for improving the rate of creating sentries, as well as foam or traps. It is more cost-efficient at sentry spawning than its predecessor, allowing up to five sentries (six with Vigilant Sentries) at a time per Engineer instead of two or three. As a crosspath for foams and traps, it's the preferred crosspath if utility is less required.

For Cleansing Foam, the rate boost does better than extra pierce when handling Regrows, in addition to the stronger sentries. For Bloon Trap and XXXL Trap, both benefit from faster trap refreshment rates, but suffer from a lack of trap repositioning and manual collection, and their created sentries may steal possible pops unless the Engineers are placed behind an obstacle.

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: Spawn rate increased ― 7s → 6s

2-1-0, 2-2-0, 2-3-0, 2-4-0, 2-5-0

•  Larger Service Area now grants +4 range to Sentries

2-0-1, 2-0-2, 2-0-3, 2-0-4, 2-0-5

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

Version 23.0

“

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

”

2-2-0, 2-3-0, 2-4-0, 2-5-0

•  Deconstruction now grants all Sentries +1 damage to Fortified or MOAB
  • Note: Does not apply +2 damage to Fortified MOABs

2-0-4, 2-0-5

•  Faster Engineering reduces the delay of the trap attack more ― -20% → -40%

Version 29.0

•  Overall cost reduced by $50 (due to cost changes for previous tiers)

Version 31.0

2-3-0, 2-4-0, 2-5-0

•  Cleansing Foam now causes Sentry projectiles to remove Camo and Regrow properties

Version 33.0

“

The MOAB offense of top path lacks for a mainly dps tower that is quite complex to use [...] the 320 crosspath will now be able to double dip on the Fortified & MOAB damage bonuses that it gains.
— Update notes

”

2-2-0, 2-3-0, 2-4-0, 2-5-0

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

Version 36.0

“

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.
— Update notes

”

2-0-5

•  Trap attack: Deploy rate reduced ― 2.8s → 3.48s
  • Note: 2.8s min cooldown is unchanged

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 46.0

“

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.
— Update notes

”

2-0-3, 2-0-4, 2-0-5

•  Double Gun Sentries now shoot two projectiles at once

Version 46.2

2-0-3, 2-0-4, 2-0-5

•  Double Guns no longer reduces Sentry pierce by 1 (bug fix)

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

”

•  Nail: No longer has +1 bonus MOAB damage (bug fix)
•  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 spawner: Attack cooldown reduced ― 6s → 5s (attack speed increased by 20%)
  • Note: Effectively allows one more Sentry at a time without any attack speed buffs

2-3-0, 2-4-0, 2-5-0

•  Faster Engineering reduces the foam attack's cooldown more ― -40% → -50%

2-0-4, 2-0-5

•  Faster Engineering reduces the trap attack's maximum delay more ― -40% → -50%

2-0-5

•  Faster Engineering now reduces the trap attack's minimum delay by 25%
  •  Stacks with changes to the non-crosspathed minimum delay; overall minimum delay with this crosspath reduced ― 2.8s → 1.4s
