Fighting off zombies is going to be much easier with these Electrified Riot Shields. Wait a second…. electricity does not even affect regular zombies. In reality, these shields are designed for prison guards, security professionals, and anti-riot units. They have sparking display points on the front as a deterrent. If they touch you, you become immobilized. When you have these, you have a better chance of defending yourself. When you see them, run.
