Find a New Pacific Acrology OS access terminal.
- The Guardian will be inside the New Pacific Arcology and need to find a terminal to gain a map of the facility.
- Go to the right-hand side of the overgrown pool.
- You will see an open sliding door.
- Go inside this door, up the ramp ahead on the left and then the next one ahead on the right.
- Once again, turn left and follow the hallway forward.
- It will go up, make a slow u-turn, lead to some turnstills to pass through or over, then once again, around a slow turn.
- This will bring the Guardian into the Festering Halls
- To the left of the door in front of you is an OS Access terminal that your Ghost needs.
