While playing Manor.wad, a level in The Master Levels for Doom II, a bug occurs that causes everything alive to suddenly attain 'ghost' status.
Recorded in 1998, this demo captures the first time I encountered the previously unknown and very rare 'All Ghosts' bug.
A few moments after I enter the second room, the monsters and I become almost completely intangible. I start to wander around, a little unsure of how to proceed, when I'm suddenly killed as I try in vain to open a door.
That event eventually contributed to my research in developing the Doom II Ghost-Monster FAQ, at https://classicdoom.com/ghostfaq.htm
