You Have No Power Over Me - Call of Duty: Black Ops II

You Have No Power Over Me - 15

You need to kill the Electric Zombie - Avogadro, without being harmed.

You will need, either;
EMP Grenades
OR
Galvaknuckles

Firstly you need to turn the power on. You need to build the Power Switch at the Power Plant, to build the Power Switch you need to find;
1 - Zombie Hand
2 - Lever
3 - Backboard

EMP Grenades are found in the Mystery Box
Galvaknuckles are found on the roof of the Diner, to get up there you need the Escape Hatch for the bus and place it on the roof in the opposite corner of the Speed Cola Perk Machine.

Then turn on the power, this will power up all Perk Machines and Spawn Avogardo. It may take up to 5 rounds for Avogadro to spawn near you, you will know when he is near you because Thunder and Lightning will begin to strike nearby.

Now as soon as he spawns, throw your EMP Grenades or melee him with the Galvaknuckles, killing him as quickly as possible.

This is a reference to the Movie "The Labyrinth", where Sarah says to David Bowie, "You have no power over me."
