Reminds me of one of the Der Reise radio's where Dr. Maxis is snapping his fingers at the zombie to get it to listen, maybe the zombies are retaining more of their humanity or the gas mask ones retaining their training(since they roll around corners etc.) since they do appear to have been guards or military personal at one point. Maybe its just the new engines etc. allowing treyarch to improve their ai for the hell of it but maybe we are seeing the progression of 115 testing? However, this is just a thought/I have nothing to support it.

Or Reagan if he was involved "we begin bombing in five minutes"

hit the info tab and they state they are un-official/fake. Case Closed

Maybe Sparky is the original HellHound? Who knows.. Samantha's pet dog fluffy/her puppies were the originals so it couldn't be that

Was thinking about this yesterday when I was reading someones Abracadavre analysis. You know how some people(especially with the release of the new map/song) talk about how Samantha has two different sides?(The Innocent & 115/demon Sam) Maybe these rooms have nothing to do with telling the story about what occurred with the teleporter but they may actually be a representation of Samantha's Mind and the two sides she has. This would explain the presence of the demonic teddy bear(her corrupt side) in the bloody room. Just my thoughts.
