Suggestion: New "Monster Event" Ideas?

[hainesftw]

You basically summed up my thoughts on the issues. I don't believe monsters despawned in Penumbra: Black Plague, so if they either reverted to that or did as you said and gave no music/sound cues to when it went away, the terror would be much heightened. And more random monster spawns would be pretty terrifying as well, but they would have to work on a lot of code to ensure that you wouldn't just be guaranteed an instant death by a monster spawning 5 feet in front of you around a corner; that would just be cheap and detract from the experience.
