Strategy

This section was last updated for: version 52.2

Spy Plane offers much potential for high-skill early Camo popping, particularly against early stages of Phayze on Boss Rush. As a crosspath, it is largely reserved for situations needing inherent Camo detection (such as Least Tiers or when fighting Phayze).

  •   Sky Shredder now grants pineapples +2 damage to Ceramics
“
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
”
  •   Pineapple: Base pierce decreased ― 40 → 20
0-2-1
  •   Pineapple: Now gains +12 pierce from Sharper Darts
    • Note: Pineapple pierce decreased from 40 to 32
“
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.

  •   Dart: Projectile size increased ― 2 → 3
  •   Main attack: Attack cooldown reduced ― 2.1s → 1.68s (attack speed increased by 25%)

  •   Pineapple: Attack cooldown reduced ― 1.6s → 1.2s (attack speed increased by 33.33%)
“
Monkey Ace has had an overall rework to a lot of different upgrades in order to highlight the x1x Exploding Pineapples upgrade as a buff to all explosives [...]
— Update notes

3-2-0, 4-2-0, 5-2-0
  •   Exploding Pineapple now grants +4.5 units to the radius of the missile attack's explosion ― 30 → 34.5
  •   Exploding Pineapple now grants +2 pierce to the missile attack's explosion
0-2-4
  •   Exploding Pineapple now grants +15 pierce to the main attack's bombs
    •   Overall pierce reduced ― 60 → 45 (due to changes to the projectile's base pierce)
  •   Exploding Pineapple now grants +3 units to the radius of the main attack's bombs ― 20 → 23
“
More of a straight quality of life, Ace has gained a new special toggle button to allow it to turn back and fly in reverse on any selected flight pattern.
— Update notes
”
  •   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
”
  •   All attacks: Spy Plane now deal +1 damage to Camo
“
Exploding pineapples gained a larger rate bonus from crosspathing than the main attack did to make up for its base rate being so poor, so we’re fixing that poor base rate while keeping the crosspath bonus the same.
— Update notes
”
  •   Pineapple attack: Attack cooldown reduced ― 2s → 1.7s (attack speed increased by 17.65%)
1-2-0, 2-2-0, 3-2-0, 4-2-0, 5-2-0
  •   Pineapple: Attack rate buff from Rapid Fire reduced ― -40% → -25%
    •   Stacks with changes to the attack's base cooldown; overall attack cooldown increased ― 1.2s → 1.275s (attack speed reduced by 5.88%)
“
Minor catchup changes to some parts have fallen out of line slightly due to balance changes for other parts of the Ace.
— Update notes
”
  •   Pineapple: Attack cooldown reduced ― 1.7s → 1.6s (attack speed increased by 6.25%)
    •   Overall attack cooldown with Rapid Fire reduced ― 1.275s → 1.2s (attack speed increased by 6.25%)
“
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
”
  •   Bonus damage to Camo Bloons increased for all attacks ― +1 → ×2
3-2-0, 4-2-0, 5-2-0
  •   Bonus damage to Camo Bloons increased for all attacks, except Anti-MOAB missiles ― +1 → ×2
3-2-0, 4-2-0, 5-2-0
  •   Missiles now drop an Exploding Pineapple on impact, with the same stats as the regular pineapple attack
“
Pineapple radius is scaling up to match x3x Bomber Ace’s explosion size, since there are virtually no recorded instances of these actually hitting a Bloon yet (Fingers crossed!)
— Update notes
”
  •   Exploding Pineapples: Explosion radius increased ― 25 units → 35 units
