You start out with a superpowered (4/4) spike factory at the end of the track. Every second, it shoots out 5 spiked mines, 10 spiked balls, and 10 stacks of MOAB-SHREDR spikes (each stack has 11 spikes). IMPORTANT NOTE: THE SPIKE FACTORY HAS A LEVEL 2 SHIELD. All other towers don't, unless you place a Shield Generator.
