Spike Storm ability: Shoots out a thick layer of spikes over the entire track.
~ BTD6 upgrade description

Spike Storm is the fourth upgrade for Path 2 for the Spike Factory in Bloons Tower Defense 6. It grants an ability that spawns extremely quickly roughly over the whole track for 1.0s. By default, a minimum of 200 spike piles will be produced for the duration of the ability, because the ability attacks 200 times per second. Just like MOAB SHREDR, the previous upgrade, all spikes from this Spike Factory including those from the ability will deal +4 damage to MOAB-class bloons, inflicting up to 5 damage to those bloon types per spike. Cooldown for this ability is 40 seconds, and spike piles spawned from the ability last for up to 20 seconds before each spike pile starts disappearing.

Spike Storm ability has a few special interactions with crosspathing. Bigger Stacks increases the pierce of each spike by +5, and White Hot Spikes allows it to damage Frozen and Lead, just as it would in BTD5. Long Reach increases the lifespan of the ability spikes by 50%, lasting for 30 seconds instead of 20 seconds. Because any attack speed buff increases the total number of spikes spawned via the ability, the brief start-of-round attack speed bonus from Smart Spikes is able to affect the Spike Storm ability.

It costs $4250 on Easy, $5000 on Medium, $5400 on Hard, and $6000 on Impoppable.

Strategy[edit | edit source]

Summary[edit | edit source]

Spike Storm is a powerful option for covering spikes across the screen for widespread damage. Due to inheriting the properties of MOAB SHREDR, which allows it to deal increased damage to MOAB-class bloons, its ability is a good option for severely hurting the HP of small groups of weaker MOAB-class, such as the Round 95 DDTs and Round 99 Fortified DDTs (with White Hot Spikes), or inflict large damage to larger spaced MOAB-class, such as the Round 100 BAD. When paired with Bigger Stacks and White Hot Spikes, its main strength comes from countering DDT layers and countering the DDT offspring of singular BADs, provided that other defenses handle all other bloon types so that its spikes do not waste on much weaker bloons, as well as singular BADs themselves.

Tips[edit | edit source]

  • 2-4-0 Spike Storm is useful for countering DDTs and inflicting large damage against singular BADs.
  • One 2-4-0 Spike Factory costs $12,205 on Hard Mode.
  • Attack speed buffs increase the number of spikes ejected from the Spike Factory when the ability is used. Buffing the tower through Overclock and Call To Arms is suggested to increase the towers effectiveness.
  • The Spike Storm ability is more effective on shorter maps and maps with no multiple entries and/or exits, as the spike storms are densely packed. This makes it a very viable option for maps like #Ouch or Geared.
  • It is usually recommended to go for Path 1 crosspathing, as the extra spikes and Lead-popping power typically outweigh the benefits of increased spike lifespan and early-round speed boost. However, Path 3 crosspathing is useful for dealing early-round damage if activated during the short speed-buff window.
    • For context, a 1-4-0 Spike Storm versus a single Round 100 BAD will deal around ~5500 damage per ability on most single-lane maps. A 0-4-2 Spike Storm will deal around ~9000 damage if activated at the start of the round, but only deal ~4000 damage afterwards.
  • Spike Storm and its ability is weak against Super Ceramics, so use this with caution in the late-game.

Trivia[edit | edit source]

  • Spike Storm cooldown was decreased overall since initial release of BTD6. Instead of 60 seconds in BTD5, it is now 40 seconds.
  • On earlier versions of BTD6, particularly on initial release, Spike Storm with Bigger Stacks or White Hot Spikes only featured a larger spout with a black color instead of red, without the change in the body color.
  • Although the patch notes for Version 7.0 stated that Spike Storm formerly costed $6000, this was in fact incorrect, as it costed $6500 on Medium like the BTD5 counterpart.
