Now that we know that in the old multiverse, planets like Mars and Venus (and even moons) have 115 meteor deposits and ancient civilizations, maybe this was the "source" that the NSA found, who, like the Thurston cult, uses 115 to teleport to other planets (via 935 scientists' help, of course, like with area 51 teleporter)

I know the cypher probably meant something else back in BO3 under Jason, but the zombie storyline has been led and written by a bunch of people over the years, so, call it a retcon or whatever, but I think this should be the current canon lore for this cypher and zombies as a whole.

I hope some zombie content creators learn about this soon.
