I checked my Gamertag just to be sure and I've got all 68 Ghosts. Something like this for missing Grimoire score would be great though. I'm at 2615 on Xbox so I think I've mostly just got to play Crucible for my remaining Grimoire score. That is of course until House of Wolves and the other expansions along with the Playstation timed exclusive content comes out on Xbox. Then I've got to try and get the almighty Hawkmoon and the other exclusive weapons.
