For the BTD5 counterpart, see Monkey Intelligence Bureau (BTD5).
The Bureau grants special Bloon popping knowledge, allowing nearby Monkeys to pop all Bloon types.
~ BTD6 description

Monkey Intelligence Bureau (sometimes abbreviated as MIB for short) is the third upgrade of Path 2 for the Monkey Village. It allows all the towers in the radius to become granted the "normal" damage type. It does not necessarily grant MOAB-class popping power, but it allows all towers within its radius to pop Lead Bloons, Thermal Bloons, Frozen Bloons, and Purple Bloons.

It costs $6375 on Easy, $7500 on Medium, $8100 on Hard, and $9000 on Impoppable.

Description[edit | edit source]

Appearance[edit | edit source]

Monkey Intelligence Bureau turns the entire Village into a high-tech pentagonal-shaped steel building. It retains its pair of rotating radar speakers on top of an radio tower stand. Across the building, it has three orange windows per side. The door and entrance appear to be made of concrete.

Mechanics[edit | edit source]

Just like in BTD5, the Monkey Intelligence Bureau upgrade allows nearby towers to damage any bloon type. More specifically, the Monkey Intelligence Bureau awards the normal damage type to all nearby towers, allowing them to deal damage to any type of bloon. Most of the non-MOAB- status effects can additionally affect any type of bloon up to Ceramic.

  • Black and Zebra Bloons can be popped by all forms of explosive damage.
  • White and Zebra Bloons can be frozen by freezing damage (i.e. from Ice Monkey, Ball Lightning with "Cold Front" MK, and Sentry Expert's Cold Sentry).
  • Frozen and Lead Bloons can be popped by sharp projectiles (e.g. darts, tacks, blades) without special upgrades.
  • Purple Bloons can be popped by attacks that involve energy, plasma, or fire.
  • DDTs can be popped by sharp projectiles (e.g. darts, tacks, blades) or explosive damage without special upgrades.
  • Lead Bloons can be frozen and popped by freezing damage (i.e. from Ice Monkey, Ball Lightning with "Cold Front" MK, and Sentry Expert's Cold Sentry).
  • Ice Monkeys can re-freeze frozen bloons without needing the Re-Freeze upgrade.

However, this will not grant power to attack MOAB-class if the tower cannot attack them, like BTD5. It also does not grant a small number of non MOAB-class status effects with the power to affect specific bloon immunities:

  • Pin effects will never halt progress of Leads or Ceramics
  • Knockback (from Super Monkey) always has a weaker effect on Leads and Ceramics
  • Downdraft blowback never blows back Frozen.

Strategy[edit | edit source]

Summary[edit | edit source]

This upgrade is very expensive in concept, but it proves to become very effective at countering DDTs. Strong DPS towers whose weaknesses are only specific bloon types would strongly benefit from this upgrade. The majority of popular strategies often rely on MIB to reduce weaknesses against DDTs. On some occasions, it is for energy-based Magic Monkeys to damage Purples, most specifically to survive the pre-blimp stage of Round 95. The other possible popular use is to allow towers to damage Frozen Bloons to fix the negative synergy between sharp-based attacks and Ice Monkeys, specifically 0-1-2 Re-Freeze Ice Monkeys or Icicle Impale.

Tips[edit | edit source]

  • The "better" crosspath depends on the situation, but 2-3-0 MIB is generally better overall, as it provides more coverage and provides Jungle Drums effects.
  • Do be sure to provide some discounts via Monkey Commerce before upgrading to this upgrade, to save a good chunk of money.
  • In CHIMPS, it is important to try discount an MIB village by Monkey Commerce, although it is quite expensive to do so. The cost for buying the two separate Villages is $12,365 (a 0-0-2 village and a 0-3-0 village in range of each other) rather than $11,800 (just a 0-3-0 village). The difference is $565. If you are planning to put other monkeys in range of the towers then this difference is negligible.
  • Monkey Intelligence Bureau is very effective at countering the weaknesses of attacking DDTs, especially good for high-attack powerful towers with Lead or Black weaknesses.
  • Despite how overpriced the MIB upgrade is, especially in BTD6, MIB will make dramatically improve certain upgrades by eliminating a wide variety of attack weaknesses.

Trivia[edit | edit source]

  • The Monkey Intelligence Bureau upgrade icon is a monkey in black three-piece businesswear wearing black sunglasses.
    • The same upgrade icon looks similar to the COBRA's Misdirection tower avatar in BTD Battles.
    • The building could also be based off of the pentagon being shaped similarly.
    • It might be a reference to the movie Men in Black, considering the name, and the monkey with sunglasses in a suit.
