~ BTD6 upgrade description

MOAB SHREDR is the 3rd upgrade for Path 2 for the Spike Factory in Bloons Tower Defense 6. All spikes from this Spike Factory will deal +4 damage to MOAB-class bloons, inflicting up to 5 damage to those bloon types per spike. One single spike pile alone can deal up to 25 damage to a single MOAB-class bloon. Unlike in BTD5, upgrading to the MOAB SHREDR upgrade does not grant the Spike Factory with a substantial attack speed bonus.

It costs $2125 on Easy, $2500 on Medium, $2700 on Hard, and $3000 on Impoppable.


  • It is worth upgrading the Spike Factory further to Spike Storm, where its ability will inflict massive damage to blimps throughout the entire screen.
  • Do not rely on MOAB SHREDR for popping blimps, as Ceramics can easily break apart the anti-MOAB defense.
  • It is almost always better off going for 2-3-0 MOAB SHREDR than 0-3-2 MOAB SHREDR, because the double pierce usually is far more efficient than the bonus target priorties and slight start-of-round speed boost. In addition, the White Hot Spikes upgrade allows popping of Leads and Frozens, and can be a big help against fighting DDTs.
