That's really interesting I never thought of it like that, I always thought mob of the dead as a separate dimension, with origins starting off the whole thing, because in the cut scene she says tomorrow it your turn. The end of black ops 1, when Richtofen gains control, is "tomorrow". Black ops 1 and origins has Samantha, then Black ops 2 is Richtofen's turn to control them, with Maxis tryig to take over, maybe thinking his daughter shouldn't be playing with this boy and trying to save her by taking over the game from Eddie. MOTD has no linkage into my theory, however, and my thoughts on that is that it is just a random DLC map within its own dimension controlled by Satan (three dog heads are Cerberus, 6 zombies to each = 666, different demonic announcer) and the inmates are trapped in an infinite loop constantly being revived until Weasel can get his revenge and the other three pay for their heinous crimes. What does everybody else think?
