There is 1 Dead Ghosts to be found in Echo Chamber. They can be collected on any mission or during a patrol. Each Ghost can only be collected once per account.
Ghost 1[edit]
This Ghost is found in the Boss chamber. Attempt to get this Dead Ghost before the energy walls start moving to make things a bit easier. From the entrance to the Boss chamber, look to the left and spot these pillars. Jump from one to the next to get to the top of the pillar closest to the Boss's starting point.
Turn and face away from where the boss starts. Look up to see the Dead Ghost above you.
