| ~ BTD5 Official Description |
Spiked Ball Factory is the third upgrade for Path 1 of the Spike Factory in Bloons Tower Defense 5, costing $2040 on Easy, $2400 on Medium $2590 on Hard and $2880 on Impoppable. It makes the Spike Factory produce spiked balls that pop 16 bloons (20 on Mobile) each and do three times the damage to Ceramic Bloons. The spiked balls are black balls with orange spikes coming from them. Upon upgrade, a slight range increase occurs (BTD5 only). Usage in great numbers will destroy small numbers of MOAB-class bloons, but is not reliable in late game. If many are used, be prepared for a large amount of lag.
In BTD6, this upgrade makes a return as the third upgrade of Path 1 for the Spike Factory as Spiked Balls. It also pops 16 bloons per ball, but it now deals 2 damage per spike, +3 damage to Ceramics and +1 damage to all Fortified Bloons, including MOAB-class with the Fortified property.
