White Hot Spikes (BTD4-BTD5)


 * Not to be confused with Red Hot Spikes, a powerup in Bloons Monkey City.

"Cuts through lead like a hot spike through... lead."

- Official Bloons TD 5 description

White Hot Spikes is the 3rd upgrade in BTD4 and the 2nd upgrade of path 1 for the Spike Factory in BTD5. In BTD4, it costs $300 on Easy, $350 on Medium, and $380 on Hard, and in BTD5, it costs $765 on Easy, $900 on Medium, $970 on Hard, and $1080 on Impoppable. It enables the Spike Factory to produce spikes that can pop both Frozen Bloons and Lead Bloons. The spikes turn red at their tips.

Summary
It is quite an expensive upgrade for lead-popping power, but it can help if needing to stop leaking Leads, damage DDTs, or synergize with Ice Monkeys.

Tips

 * 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.
 * This upgrade pairs well with Spike Storm, as it allows each spike storm ability to pop D.D.Ts.
 * This upgrade can be useful in certain levels of Bloons Monkey City, where Regrowth Leads might be problematic.

Trivia

 * Even though it's called white hot spikes, and the artwork shows spikes that are white at the top and orange at the bottom, the spikes actually appear reddish-orange in the middle with black at the bottom, although the very tips are white.
 * MOAB-SHREDR Spikes have the picture of white hot spikes on a MOAB even though this upgrade can be reached without buying the white hot spikes upgrade (e.g. 1/3 spike factory).
 * The bottom of the spikes are not as hot, because they are black and not red or white.
