Secret Treasure Hunt

In November 2011, Introversion did a secret treasure hunt after the Humble Bundle launched, embedding images from Prison Architect in the Subversion tech demos and sending others out to a few select journalists. There was five polaroids that when pieced together, produced a string of characters that led to a hidden Prison Architect  website.
