Visiting Avernus, then engine fix in Upper City with Gondians. I'm waiting for the removed content in the DE
But there is no removed content, isn't it? That supposed leak from the steam post turned out to be fake unless I missed something. So that's story overhaul, or rather complete retcon considering what VA said and the fact that she's the only companion that can be turned into the mindflayer
I think there is. Swen told in some interview, that Upper city was fully playable and they removed it from the game two weeks before the release. The hints like enriched infernal ores which were not properly removed from the game supports that theory, that the final fix was possible in the Upper City. Who knows what is true and what is only speculation.
But it makes complete sense for me. You go though the whole game and now you enter Upper city where you save Karlach in the last minute and then there is epic game ending in this location.
