Being inspired by the newest Black Ops II's Zombie map/mode 'Green Run'/Tranzit, I think have enough courage to bring this idea to light.
Kind of like the Christmas Specials for the TV show, I was going to write a special halloween episode for my fanfiction Moths Shall Play called 'Warehouse of the Dead' The idea of the episode is that a non-artifact zombie apocolypse has struck and only the Warehouse is the remaining 'safe zone' left in South Dakota. Inside, the Consultants and some of the remainin citizens of Univille are surviving.
What I need are some artifacts that would be rather useful in the Zombie Apocolypse. Currently, Richtofen's Wunderwaffen will appear as well as Tomas de Torquemada's chain, but I'm drawing a blank on some of the other artifacts that they would let the survivors use in case of the threat of being overrun.
