At the beginning of Act 2 (in New York apartment) on the PC (via Steam) there is a QR code.
It is located in Alan's Office (if I remember correctly), and it says:
Huh. Turns out this isn't too bad even if you're not sitting on a couch when you play it. Who knew!
Is there also a QR code in console versions here? If so, I would assume the majority of console players would, in fact, be playing on a couch. Therefore, does it say something else?
