I've been playing BTD5 and BMC, and whenever I upgrade the spike factory from 0-2 to 0-3, it seems to make spikes FASTER than a normal 0-2 spike factory. Is it just me, or are they faster?
Yes, the right path tier 3 upgrade for a Spike Factory (MOAB-SHREDR) increases the speed as well as the damage to MOAB class bloons.
Effect: Each spike does 4 damage to M.O.A.B. Class Bloons. Also shoots at a faster rate.
Attack rate improves to once every 18 frames, or half a second.
