Collecting a Dream (all skulls) has been unlocking for people since the ATN patch. Maybe try a hard reset of your console to see if it unlocks when you next load up the game. Completing campaign on legendary/heroic hasnt been working for anyone for ages.The Turbanetor wrote:1) Xbox 1
2) Campaign legendary, and All Skulls achievement
3) 2. I finished the campaign on Legendary but nothing unlocked, I only got the normal campaign and missions completed achievement.
