Amnesia: A Machine For Pigs Discussion Topic Part 2

[Tesseract]

I watched the trailer a few times and noticed something rather interesting in the gameplay footage towards the end - I pointed this out a while back on the youtube video and I thought I might share it here.

In the chase scene when the player runs into the cage and looks out through the other cages I noticed something rather interesting: There is something moving behind all of the other cages - obviously - but the thing behind the cages is thought to be the 'monster' walking around searching for the player, after observing its movement carefully I came to the idea that the movement behind the cages isn't the monster, I think it's some sort of motorized rail that moves carcases from one area of the level to another; however, I don't think all of them are dead as you can hear an 'oink' come from the area they're travelling to. The 'oink' I first thought was the monster but you can clearly hear it run off to the right. The reason I think they're travelling down a meat line is because I see no footsteps and the movement is very consistent, I don't see any animation coming from it other than it's moving from one area to another: no head bobbing and no other bodily movements.
