Step 1. Build the turbine (consists of the mannequin, the tail & the fan)

Step 2. Turn on the power

Step 3. Turn OFF the power (If you do not turn off the power, you will not be able to communicate with Maxis)

Step 4. Travel to the spire and kill the last zombie when lightning is above you (This will cause the Avogadro to spawn, (galvaknuckles and emp grenades are recommended, but not needed))

Step 5. One player must go to the diner, another player must go to town and the other 2 players must go to the spire. You must place down your turbines at exactly the same time. (microphones are necessary to make it a WHOLE lot easier)

That's it, you've completed Maxis' side of the easter egg!
