There is no story really to this map, other than it features four Modern Warfare 2 characters, Modern Warfare 2 weapons, and is based mainly off of modern Warfare 2.
The characters in the map are Simon “Ghost” Riley, Gary “Roach” Sanderson, John “Soap” Mac Tavish, and Michael Foley. The map takes place in the same place as the multi-player map Scrap Yard, except the map is more zombie oriented.
The boss round on this map is a round of rather strong crawler zombies. The round appears as a regular zombie round, but they are stronger than regular and there are only about 15 of them. They emit a cloud of red, extremely harmful Nova gas. If too much gas is near the player, they may be downed unless they have the perk Toxin Immune.
Perks and Power-Ups:
Toxin Immune (allows you to be immune to toxin emitted by Nova 6 crawler zombies.)
Weapons from the mystery Box:
Barret .50 Cal
