The Storm Spikes were the upgraded version of Tesla Spikes, where the beams extended further when fired. When an enemy was shocked by one of the Storm Spikes, the electric shock would connect with another enemy nearby (due to the spikes now containing an isokenetic refractor), and he/she would receive a painful shock.
"Congratulations! You have just upgraded to Storm Spikes! Each spike now contains an isokenetic refractor that leapfrogs electric currents from one enemy to another! Another defensive innovation from your friends at GrummelNet!"
