My theory

[RedDeadRiot]

I'll keep it short and sweet, so pretty much, in the campaign the whole backstory is there's a numbers station, right? And that's on a boat right? The numbers "call" to the people who had been brainwashed right? In the image that was put out by the CoD HQ you can clearly see what looks like a mast of a ship that had crashed. What if whoever is behind the zombies, figured out a way to alternate the code to call to zombies or turn people who had been brainwashed into zombies?

I'm looking up pictures/ cutscenes to try and put things together. It makes sense though if you REALLY think about it, it would tie the nova gas into the zombie storyline as well. Again this is just a theory, discuss any way to debunk my theory etc etc.

EDIT 1: Okay, so below is the picture that was on the CoD HQ, it plays no significance, other than the blue box which shows a mooring line, which means that the ship is not crashed, that it is indeed "parked" there. The Red box shows a escape dingy confirming that it is indeed a boat. Green box just shows the mast.

EDIT 2: Upon looking closely, you can see the dingy is at an awkward angle, if you look on the support holding that catwalk up you can clearly see that there are beams that are bent and resting on the ledge, which means damage, but the mooring lines are out? My brains hurting a little right now to be honest.
