Engineer Monkey (BTD6)

Engineer Monkey iterations: BTD5 • Battles • BMC • BTD6 • Battles 2

Engineer Monkey
Holds a trusty nail-gun to pop the Bloons. Can upgrade to create its own nail-shooting sentry turrets.
Category Support Cost $300 — Easy $350 — Medium $380 — Hard $420 — Impoppable Hotkey L Introduced Version 12.0

The Engineer Monkey is a Support tower in Bloons TD 6, introduced in version 12.0. It can be unlocked at levels 22, 23, 24, or 26.

The Engineer Monkey attacks by firing sharp nails at nearby Bloons, which can pop up to 3 Bloons each. It has above-average attack speed by default, but it cannot pop Lead Bloons or frozen Bloons, and it cannot detect Camo Bloons. It can be upgraded to deploy Sentries to increase its firepower, or dispense foam that removes Camo, regrow, and lead properties, or pin Bloons in place on each hit, or deploy traps that capture Bloons and convert them to extra cash, or boost the attack speed of other towers with its Overclock ability.

Strategy

This section was last updated for: version 52.0

At base, Engineer is a stronger Dart Monkey, with higher attack speed and pierce but a significantly higher cost. An Engineer-Dart start can work on single lane maps, most notably Blons but not on Workshop, while an Engineer-Wizard start can work on easier maps. Early on, top path upgrades give good single target damage, while Pin and Double Gun can save large amounts of money on single lanes, such as for an early Captain Churchill.

Overclock and Ultraboost are Engineer's main uses, greatly boosting the power of almost any tower in standard, Freeplay, and Boss Events, while Cleansing Foam can serve as decamo or Bloon slowdown when crosspathed with Pin. Bloon Trap focuses on extra money generation and is strong starting from the 30s through the 50s, and the top path serves as a pure damage path with high power and low consistency.
