My third pair of pants has been changed and Im not too sure how long I can keep them clean. Just.......wow
That secret is also a secret internally, with a total of maybe four people in all of Bungie that knows about it. I don't. That stuff was placed by Joseph Staten- I had no role in it.
I was very doubtful the glyphs held any secret but this outright proves they do.
BOB scripts were written by different designers, we tried to remain consistent, but there may be subtle differences between them. For my missions, I generated a random number at the beginning of the script and that determined which Bob would spawn. It is not possible to play my missions (or any other, for what I remember) and have no BOBs. BOBs will always spawn, if not it is a bug.
I think its safe to say we still have some BOBs out there, may I suggest you ask how many in each level and the total number of them.
