Hidden conditions

Why Some Achievements Need In-Game Confirmation

Steam displays blank descriptions for several achievements, so an older guide or community walkthrough may describe a condition that changed after Early Access. Do not treat an old chapter route as a guaranteed current unlock; record the chapter, boss state and current patch when testing.
