There must be some major bug differencies between the physical copy and the one bought on Steam. I myself have a physical copy of the game (so called Valhalla Edition), and I haven't been noticed quite any of these bugs people keep telling here. Sometimes very rare the game crashes, but for example it never freezes. And also the rage abilities are working fine, even Christa's Gift, which many here have been telling that enemies ignore it
Does anyone else here Valhalla Edition, and does it work on you also? Or is this just my own imagination
