Description[]

Overview[]

Hotstacks (2)

White Hot Spikes producing big white hot spike piles (11 spikes due to OneMoreSpikeIcon One More Spike)

The Spike Factory gains a predominantly red appearance to reflect the heat of the spikes. By default, the spikes produced by the White Hot Spikes Factory now glow white hot at the tips of the spikes, followed by red further along the spikes. When given the White Hot Spikes crosspath along Upper Path 3, the color of spike piles from Long Life Spikes also use a similar color scheme for the tips and body, but Deadly Spikes changes the body of its spike piles to orange-to-white, and Perma-Spike spike piles have a blue base with protruding orange-to-white spikes.

Spikes produced by White Hot Spikes are changed from Sharp Type (pops Black, White, Purple) Sharp to Normal Type (pops Black, White, Purple, Lead, Frozen) Normal. There are no new attack mechanics from previous upgrades aside from normal damage.

Targeting Priorities[]

White Hot Spikes defaults on Normal targeting priority, which dispenses the spike piles onto nearby bloon track in a semi-sporadical behavior. If given Smart Spikes, it will also receive Close, Far, and Smart.

  • Normal: Targets spike piles in a somewhat sporadical way, spreading spikes as evenly as possible within its range.
  • Close: Targets the closest region(s) of track within range.
  • Far: Targets the furthest region(s) of track within range.
  • Smart: Prioritizes the track with the Bloon the farthest through it, then targets the spot on that track closest to the exit.

Strategy[]

Summary[]

While mostly used to allow Spike Storm and Carpet of Spikes to pop DDTs without additional support, White Hot Spikes can be used to synergize better with Ice Monkeys. It can also be a form of early Lead popping power, including Camo Leads, although there are other cheap upgrades that perform the same function.

Tips[]

  • Generally speaking, the White Hot Spikes upgrade is perfect for Upper Path 2 upgrades, more specifically for the Spike Storm and Carpet of Spikes upgrades, in contrast to crosspathing those upgrades with Smart Spikes, which is more situational.
    • While it helps MOAB SHREDR deal big damage to DDTs, most of the time other bloons will simply eat up the spikes, wasting potential versus DDTs. Its further upgrades, however, are the ones that benefit the most out of the White Hot Spikes upgrade.
    • This upgrade pairs well with Spike Storm and Carpet of Spikes, as it allows each spike storm ability to pop DDTs and can be a viable method of crippling many DDTs at once.
  • For Perma-Spike, it is generally preferred to go with the middle path to boost production while buffing it with an Acidic Mixture Dip to provide DDT popping power. The main weakness of this strategy is that bloons frozen atop a Perma-Spike pile will cause all the spikes to be used up, although this interaction can be rare.
  • It is recommended to get the first two upgrades of path 2 (Faster Production and Even Faster Production) before getting this upgrade, as producing spike piles at a faster rate is usually more valuable than allowing them to pop Lead Bloons.
    • The only exception is if going for Spiked Balls, where in this case it is usually better to just go straight towards 3-0-0 in most cases, unless a bit more bloon tanking is required before then. If that ever happens, purchase one attack speed upgrade, to buy some time before it is possible to upgrade to Spiked Balls.

Version History[]

Balance Changes[]

Besides base Spike Factory changes, White Hot Spikes itself didn't receive much changes. For White Hot Spikes, it only received a price swap between this upgrade and its preceding Bigger Stacks upgrade. Otherwise, most balance changes indirectly affecting White Hot Spikes are based from Bigger Stacks and the base tower.

22.0
  • NERF Base projectile lifespan reduced from 70s to 50s.
  • BUFF White Hot Spikes costs less ($800 → $600), although the overall cost of a 2-0-0 Spike Factory remains the same due to the Bigger Stacks price nerf.

  • Change Affected by Spike Factory crosspath speed changes
