The Tesla Spikes was a weapon in Ratchet & Clank Future: A Crack in Time. When deployed, the spikes shocked enemies with bolts of electricity when the enemies crossed the barrier. If Ratchet threw multiple spikes, it would create a web of electricity that increased the area of coverage. It upgraded into the Storm Spikes. It had six ammo at V1. It cost 19,000 bolts.
"Tesla spikes are the ultimate defensive weapon. One spike is effective. Two or more, and they are outright lethal! When some goons approach you, try throwing a few tesla spikes. Deadly electricity will flow between each spike, destroying nearby enemies and protecting your hide. The more you throw, the more protected you will be. Tesla Spikes. Available only at GrummelNet!"
