[2019] Is it possible to unlock all characters in the current build?

Originally posted by Desna: I unlocked all of them save for Valeria, but she seems to be behind a level 45 assasination questline, not sure if its even possible to level past 30 atm. Anyone unlocked her?

As confirmed by everyone on here :) all 8 of our heroes are unlockable during Early Access.
Missions do get harder so make sure to gear up, but they're all beatable at level 30 if you've got the right stuff.
