I saw a post earlier on Reddit suggesting Ghost centric emotes. But I was thinking what about a Ghost mission? I.E The Darkness wants to test not only you but your Ghost and somehow separates you from him. Then it's down to Ghost to traverse, hide and otherwise avoid The Darkness Brand enemy to reach you. Erstwhile a simultaneous mission where the Guardian has to do the very same to hunt for Ghost but the importance being placed on looking for Ghost because he's your friend, not just your source of immortality. I enjoyed the beginning of The Red War. Being Ghostless, sneaking around unable to regen gave me some ODST vibes, but it didn't get played on enough. A mission to find parts to heal an injured Ghost? Something that really plays up and strengthens our emotional bond with the little blighter. Just ideas, any expansion would be great.
