Also another SHIFT Code List for Borderlands the Pre-Sequel:
And someone was asking what the keys do...they unlock rare weapons and items. But beware that the items have the same level you currently have so you might save the keys when you leveled up a bit.
That was me, thanks for the reply. So, like, how many Keys for example does it require for one of these rare items? Are we talking 10 or 100?
