My mind is blown.
I am so confused... it's all so crazy. I don't get. What happened? What is the connection with Rapture? So Elizabeth ceases to exist in the new universes and therefore every universe? Is there a Columbia? What happens with those damned twins? The only time I have felt like this is when I watched The Prestige.
I am really sad the game ended. I was masterful. Among the greatest games I have ever played.
