More puzzles, and that's pretty much it.

If you're interested in playing Penumbra, Overture and Black Plague are basically two chapters of the same game. Overture is brilliant but Black Plague gets mind-blowing, if you let yourself get drawn in by it. If you've played them both and you liked the gameplay (puzzle-solving), Requiem is perfectly likeable. It's a nice bonus with the Penumbra Collection, which is a cheap way to get all three.
