Aviation Grade Glue

Aviation Grade Glue in BTD6: MOAB Glue slows MOAB-class bloons by 45% instead of 37.5%. Cost, effect and why it is on the More Cash route.

MOAB Glue slows more than normal.

In-game description

Guide

Aviation Grade Glue is a fourth-row Primary knowledge that makes MOAB Glue and its upgrades slow MOAB-class bloons by 45% instead of 37.5%. Glued blimps move at 55% speed instead of 62.5%. You need 8 Knowledge Points in the Primary tree and More Splatty Glue, plus a one-time 250 Monkey Money. It unlocks Mega Mauler and Cheaper Solution.

How it changes the game

MOAB Glue (x-x-3 Glue Gunner) is one of the cheapest ways to slow blimps. Going from a 37.5% slow to 45% means each glued blimp spends noticeably longer in front of your damage:

  • First MOAB and BFB rounds: a single 0-0-3 or 2-0-3 Glue Gunner buys more time for your main damage tower. Around rounds 40 to 63 this can be the difference between a leak and a clean round.
  • Relentless Glue (x-x-4): the stronger slow applies to every blimp it re-glues.
  • Super Glue (x-x-5): after its temporary near-stop wears off, the remaining slow on the blimp uses the improved value.

It only changes the slow on MOAB-class bloons. Regular bloons glued by these upgrades are slowed exactly as before, and other Glue Gunner paths get nothing. Bosses that are immune to glue stay immune.

Is it worth it?

Priority: good. The direct gameplay effect is solid for any player who uses MOAB Glue as a blimp stall, and the node sits on two important routes. Through Cheaper Solution it leads to Bonus Glue Gunner and then More Cash, and together with Hard Press it opens Mega Mauler for MOAB Mauler players.

Among fourth-row Primary choices, buy it at the same time as Master Double Cross, since you need both columns for More Cash. So… Cold… is lower priority for most accounts.

In practice, going from a 37.5% to a 45% slow means a glued blimp moves at 55% speed instead of 62.5%, so it covers about 12% less distance in the same time. That is often enough for one more volley from your main damage tower before the blimp leaves its range.

Where it works

Aviation Grade Glue is active wherever Monkey Knowledge is enabled: Standard, Impoppable, Primary Only, Races and Boss Events (when the boss can be glued at all). It is disabled in CHIMPS and in challenges that switch knowledge off.
