Continue to kill Zombies near the ghost until all players are able to activate the ghost and cause it to begin moving. Escort the ghost to the ghost bot at the Docks. Once completed, a red stone will be placed in the HUD indicator.
Locate the ghost in the Cafeteria and Spirit Blast it. Escort and defend the ghost until it reaches the Portal located in Michigan Avenue. All players must be together when this happens! Collect the red orb that drops near the ghost.

A ghost will spawn near the portal playing the banjo, activate the ghost to obtain the banjo and spawn blue circles on the ground.

Use shield vision to see the spirit using the levers where the logic gate symbols are and shield blast it. Head down to docks and into the east side power room go to the back of the room and interact with a sparking generator, the room will go black and you play a game of Simon Says with the panels. Once you're done all of them will blink and the room will have all the lights turn back on. This needs to be done 5 times, once completed 3 of the machines will light up - note the logic gate symbols on these machines. Grab the punch card off the shelf in the middle of the room (with the candles), go to the upstairs room in spawn and place this card into the Gorod Krovi computer. The green monitors will light up, each with a symbol on them, interacting with a monitor shows the corresponding hobo/logic gate symbol. You must match the hobo symbols from the Spawn power room to the Logic Symbols from the Docks power room that were noted. Once a symbol is matched, go to the spawn power room and see the the spirit trying to pull the levers. When it attempts to pull the lever of the symbol you just matched, shield blast it. He will become visible outside of shield vision and will pull the lever successfully. Repeat this for the other 2 symbols that were on the lit up machines at docks. Once complete, a red orb (like the one at the end of shock and denial) will drop in front of the last lever you blasted.
