Ground Zero is the Monkey Ace's path 2 tier 4 upgrade in Bloons TD 6. It grants Monkey Ace the Ground Zero ability, which when activated drops a bomb on the screen which deals 700 damage and has 2,000 pierce. This bomb has a full-screen blast radius, and can damage all Bloon types, affecting up to 2000 Bloons nearest the landing pad. This ability has a cooldown of 35 seconds and an initial cooldown of ~11.67 seconds. Once dropped, it has a delay of about 0.8s.

This upgrade also increases the damage of Monkey Ace's bombs from 3 to 15, and increases their pierce from 20 to 40. Double damage to Camos via Spy Plane is inherited and affects both the bomb salvos and the ability bomb.

Ground Zero's ability is a powerful way to destroy huge amounts of bloons anywhere on screen. In Race Events and CT Time Attack, it stands out for clearing the majority of waves; buy it quickly in advance to cool off the ability, send many rounds, and activate the ability as soon as possible. For CHIMPS, it is best used to wipe out difficult low-HP swarms, such as non-Fortified DDTs, MOABs, and Super Ceramics. Its cooldown is somewhat long, so use the ability sparingly. Versus Fortified DDTs, ensure no decamos are present, allowing one ability to wipe out all Fortified DDTs on round 99.

The basic improved bombing run does a lot of damage, which can severely weaken mid-game Ceramics in one shot, but requires heavy micromanagement to fully optimize this attack. Without micromanagement, it's quite inconsistent and still has a major Black Bloon weakness. As the ability is unaffected by crosspaths, 1-4-0 is the preferred crosspath, with 2-4-0 optional for extra darts only, and 0-4-2 may assist heavy micro of its bombs.

  • Nerf Overall cost increased by $400 (due to cost changes for previous tiers)
  • Buff Bomb: blast radius increased ― 25 → 35
  • Buff Bomb: attack cooldown reduced ― 3s → 1.5s
  • Buff Bomb: damage increased ― 2 → 4
[N]o one really noticed that this gained +8 damage for 10 seconds after ability use. So, Bombs dropped by this tower now deal 10 damage permanently
— Update notes
  • Buff Bomb: explosion damage increased ― 4 → 10
  • Nerf Ability: no longer increases bomb explosion damage by 8 for 10 seconds after activation
  • Nerf Bomb: cooldown increased ― 1.5s → 1.7s
1-4-0, 2-4-0
  • Buff Rapid Fire now reduces bomb attack cooldown ― 1.7s → 1.02s
While Pineapples are never the star of the show, the amount of pierce they have is completely unnecessary for their usage window and has only led to balance problems for Bombing Run, specifically in races. This high amount of pierce has been more evenly spread through higher tiers & crosspath.
— Update notes
0-4-1, 0-4-2
  • Buff Pineapple/bomb explosions now gain +12 pierce from Sharper Darts
Monkey Ace was never intended to be a great starting tower and instead come into power at mid- and high-tier upgrades, but since the base tower feels lacking to new players (and some of us old timers) we decided to rework low tier power into the base tower.
— Update notes
  • Buff Dart: Projectile size increased ― 2 → 3
  • Buff Base Monkey Ace attack cooldown reduced ― 2.1s → 1.68s
0-4-1, 0-4-2
  • Buff Exploding Pineapple: attack cooldown reduced ― 3s → 2s
1-4-0, 2-4-0
  • Buff Exploding Pineapple: attack cooldown reduced ― 1.6s → 1.2s
Similar to Tack Shooter Maelstrom upgrades, we have targeted a nerf to Ground Zero for race conditions by amounts which are not relevant outside of those conditions.
— Update notes
  • Nerf Ability: Pierce reduced ― ∞ → 1,000
As Ground Zero stands out in power, & enough so to make the upgrade to Tsar Bomba questionable, some upgrade cost has been moved out of Tsar Bomba into Ground Zero to make Ground Zero more expensive while not changing Tsar much other than a slight overall cost buff.
— Update notes
  • Nerf Upgrade cost increased ― $14,000 → $18,000
  • Buff Reverse flight pattern added
Spy Plane is always a lesser crosspath aside from specific challenges that call for camo detection. It has a similar vibe to Night Vision sniper so we have given it a similar buff.
— Update notes
  • Buff Spy Plane grants attacks +1 bonus damage to camos
As the price of Ground Zero has been considerably increased in the base game since then, the nerf to 1000 pierce set for races a long time ago now feels restrictive for the price.
— Update notes
  • Buff Ability: Pierce increased ― 1,000 → 2,000
1-4-0, 2-4-0
  • Nerf Bombs reload rate reduced ― 1.02s → 1.275s (undocumented)
    • Note: Rapid Fire's cooldown modifier changed from 0.6× to 0.75×
Minor catchup changes to some parts have fallen out of line slightly due to balance changes for other parts of the Ace.
— Update notes
  • Buff Bomb salvo: Attack cooldown reduced ― 1.7s → 1.6s (undocumented)
    • Note: Rapid Fire crosspath attack cooldown is reduced from 1.275s to 1.2s
Upgrades to the basic Bombing run are never why you move up this path, so we’re improving these across the board while also reducing the cooldown of Ground Zero to match the T5.
— Update notes
  • Buff Ability cooldown reduced ― 45s → 35s
  • Buff Bombing run: Damage increased ― 10 → 15
As Spy Plane crosspath doesn’t see much love we’ve gone all-in on the Camo crosspath making it a double damage bonus, which is especially good news for Ground Zero vs. Fortified DDTs.
— Update notes
  • Buff Bonus damage to Camo Bloons increased for all attacks ― +1 → ×2
Ground Zero feels like a good tower, but has had a hard time fitting anywhere being power creeped by other meta options.
— Update notes
  • Buff Upgrade cost reduced ― $18,000 → $16,000
