TOPIC CONTAINS SPOILERS
I really love the themes of this episode. I don't know if anyone else noticed but there are a lot of underlying moods that enhance the overall quality of this episode. Like the record player and torture scenes.
The torture scenes in this episode reveal what we already know about the town. That it is not a town and serves as a prison, mentally and pysically.
The cabin scene seems like something taken right out of "Night of the living dead" or of course our beloved COD zombies. With two added twists, there is a guy still there, and the zombies are even more retarded than in COD, allowing the survivors to just run out the back.
