The Pizza Code MysteryEdit

BMARGHeader

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.

This wiki details our efforts since 2012 to solve The Pizza Code Mystery: an ARG found in Black Mesa, a re-envisioning of Valve Software's seminal classic Half-Life. As of August 14, 2019 the Pizza Code Mystery is on the verge of being solved as the notoriously difficult gateway puzzle has now finally been solved. With the recent release of the Xen/Gonarch beta, the ARG has entered a new phase, seeing as the puppetmaster has indicated that the conclusion to the ARG is now in-game.
