Been playing BO4 lately and catching up on the lore of the maps, I found this cipher in classified that seems to refer to Dr Monty. The text is written on a teleporter that Broken Arrow secured on Der Riese.

Now how could this Maxis from the Ultimis dimension have known Monty at this point in time ?

Or is this refering to another "M" ?

Here's the complete cipher:

August 8th, 1947

I've been logging materials acquired from Group 935 for some days now (Major Sawyer has asked me to evaluate files pertaining to undead experimentation) and this afternoon I happened upon an old friend.

Hidden deep away in storage was Dr. Maxis' Original Matter Transference Prototype. Apparently, it was one of the items the Americans acquired when splitting Group 935's resources with the Russians. Unsurprisingly, it's in a terrible state of disrepair. Missing pieces, badly damaged, completely non-operational. To be fair, Maxis himself stopped using it after the failure of those initial tests in 1939.

While useless in its current state, it will provide great reference when we begin teleporter development at this facility. One thing I had never noticed before – scratched into the bottom of the machine was a message: "For M) , who started me on this journey."

It struck me as odd… I can't recall anyone at Group 935 who went by that initial. I haven't the faintest idea who Maxis could have been referring to.
