  • Do I need to do all side missions and get all collectables to get this achievement?
  • From what I've read yes you do. I can't say for certain though as I have completed 100% of everything but this and the secret achievement will not unlock for me.
  • I got 100% still no achievement
  • Same guys. I've even got all 3 rewards from the co-op mission. Opened a ticket with Ubisoft. No way am I being denied this after the effort put in.
  • Unlocked fine for me when I opened my last chest. You might have just unlocked it when the achievement servers were down; it'll pop in due course.
  • It unlocked overnight. Strange.
  • Yeah same thing happened to me with 20 heavy weapons kill achievement which i tried to do when the achievement servers where down so it didn't pop when it should but when i locked the day after it was unlocked and timestamped the day before.
