"It has come to my attention that strange messages have been appearing throughout Black Mesa, and have been causing somewhat of a conunDrum concerning what has become known as "The Pizza Code Mystery".
I have long suspected that there was something stRange going on during the development of this facility. The unexplained disappearances, misappropriation of funds regarding cheesy oven-baked bread products and an ominous feeling that something is constantly watching this all from the shadows, Have added up to create something that needs solving, and sOlving fast.
As a result, I am offering a small reward to the first peRson that can solve this mystery and provide me with the answers I need. Together, I'm sure you caN crack this."
