The DLC is a prequel. The history of Krat is told primarily through flashbacks, so it’s possible the DLC adds additional context. That said, the game definitely didn’t feel incomplete. Full story, complete world, and fleshed-out gameplay. If you like soulslikes, you’d probably enjoy this one too.
I’m not familiar with the backrooms. Is she going to die because she’s getting the rock out and is unaware, or is she just stuck there for eternity?
