Pin (BTDB2)

BTDB2
Pins Bloons in place for a short time when struck.
~ BTDB2 description

Pin (BTDB2) is the 2nd upgrade of Path 3 for the Engineer Monkey in Bloons TD Battles 2. It works similarly to its BTD6 counterpart.

It allows the Engineer to pin down all single-HP bloons for 1s, equivalent to a stun except affected bloons are struck by multiple nails attached. Pinned bloons are temporarily immobilized, and the status effect pins up to one layer, although an Engineer with this upgrade repeatedly attacking the same bloon will simply refresh the effect. Regardless of further upgrades or external buffs, this status effect cannot stop Lead or Ceramic Bloons, as these bloon types are unaffected by it.

Sentries with this crosspath, even without Sprockets, will be able to inherit properties of the Pin effect. Cleansing Foam with Pin does not gain a slowdown effect, unlike in BTD6.

It costs $200 and is unlocked with the purchase of Engineer Monkey.

Strategy

Summary

A simple pinning action stops bloons in place. It also works well with Sentry Gun because the sentries can pin regardless of crosspaths.

Engineer’s early game upgrades aren’t great, nor is 5xx. However, Engineer has some incredibly strong upgrades, [...]. We have altered all of these upgrades, weakening its strong points while improving its weaker ones to compensate and balance it out.
