I did AoMarksmanship, reached the Cyberdemon, figured the damage I was doing was too low, so I set a nuke, moved out of the way not knowing if it can be destroyed; got well out of the way, got plastered by Cybie, nuke at ~4 seconds - but it seemed to had gone off anyway.
Then I got this for a postmortem:

Before him 63 brave souls have ventured into Phobos:
57 of those were killed.
1 of those was killed by something unknown.
Some rumours though, say that the Cyberdemon was killed already!
Is he immortal? 5 souls claim to have killed him...
4 killed the bastard and survived.
1 showed that it can outsmart hell itself.

If it makes any difference, I had loaded into lvl3 Phobos Hell. I don't savescum, so it couldn't have been a hidden postmortem from that game, but maybe parts of it are from an earlier one, as they seem familiar enough. Still, I haven't been killed M.diff lvl3 by a Lost Soul at 60% kill ration for a long while, and the bottom details are almost current...
