- On the MyPlayer hub, press
once to get to the "CUSTOMIZE" tab.
- Select "Loot Pack Store"
- Purchase any loot pack. The cheapest is 100 tokens (you get these by completing tasks or by buying them using VC - press
on the loot pack store to do this).
- After buying the loot pack(s), press
to go to "MyLoot Packs" and open it/them.
EDIT: May be slightly glitched, like some other achievements.
