The Pizza Code Mystery ARG Wiki

The Pizza Code Mystery

quod coronae ubique vivere ergo non credidistis illi eum persequimur me, auxilium postulo non intellegere Latinam obsecro, quia caritas Dei adiuva me

sunt persequimur eum adiuvent eum

salvum illum

The Pizza is a LIE!

“

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.
