Penumbra (Requiem) Ending General Discussion

[Yuhaney]

Just to clarify, the artefacts don't seem to have anything to do with the ending. I only found 2/9 artefacts in Requiem (yeah, I suck that badly), and I still had the option to turn and leave, ending up on the ship.

Yes, but if you collect all of them, you get something little extra. Same thing works with Black Plague's artifacts.
