My Theories for CoD Zombies

Blood of the Dead

# Richtofen was sacrificed because this one was the 'nicest'. This meant he was more willing and ready to lay down his life to secure his comrades could further themselves towards the 'better future'.

# Albert 'The Weasel' Arlington is the only Mobster to appear as a bird because he is bound to Purgatory, not Hell. The bird is trapped in the cage.

# Only two ghosts assist in holding Brutus back during the EE. These ghosts are Sal and Finn, who repented for their part in murdering Albert, whereas Billy believed Albert deserved what he got.Alcatraz in MoTD is the Purgatory version, while BoTD is the Hell version.
