Spike Factory

MultiplatformFlash

Each round generates piles of road spikes that can pop 5 bloons each.

Generates piles of road spikes on bits of nearby track. Each pile can pop 5 bloons, and unused spikes disappear at the end of each round.

Cost	Multiplatform: $640 — Easy $750 — Medium $810 — Hard $900 — Impoppable Flash: $640 — Easy $750 — Medium $810 — Hard Deluxe: $595 — Easy $700 — Medium $755 — Hard

The Spike Factory is a tower in Bloons TD 5. It unlocks at Rank 19.

It dispenses spike piles onto random areas of track. Spike piles each have 5 pierce, with a visual representation of pierce based on pierce remaining. Spikes last up to 70 seconds or 1 round, whichever comes first. It can be improved to strengthen each spike pile into spiked balls and mines, or attack significantly faster and disperse MOAB-shredding spikes throughout all paths.
