Insta-defense

"Use 5 Insta-Monkeys in Co-op mode"

- BTD6 achievement description

Insta-defense is an achievement in BTD6, released in Version 11.0. It can be achieved by placing any tier Insta-Monkey with in a Co-Op Mode game 5 times. Earning this achievement will reward x2 Cash Drops and one Pontoon.

Strategy

 * Note that it does not count Insta-Monkeys placed by other players; the Insta-Monkeys need to be placed by yourself.
 * Avoid using tier 5 Insta-Monkey just for this achievement, since this achievement doesn't care about tiers.
