[SPOILERS] Theory: Is the Schrödinger Cat achievement foreshadowing?
Okay, I just saw the video of the abyss with Swann's voice over and it made me think that maybe the abyss has some sort of influence on reality at a quantum level, making things exist in more than one state at once (Swann says things like "here and unhere", etc.). The first relevant decision we make in the game is naming Swann's cat and, therefore, choosing its colour. Could the Schrödinger Cat achievement be more than a joke and actually be foreshadowing something? Could different realities be overlapping?
