Ultimate Doom in VR - E4M7 (QuestZDoom)

Did I one-shot a Cyberdemon with a BFG? I know this isn't a vanilla-compatible sourceport, and thus it doesn't count toward anything, but it seems like that would be a rare event. My subsequent run of this map took the usual 3-5 shots to kill it.

There used to be four secrets in this level, with two of them being unobtainable. It seems the unobtainable secrets were removed from this sourceport. No voxels again, since large number of voxelized monsters in the outdoor area kills the framerate.
