Kino and before, all were centered in Japan and Germay mainly the axes teritory, so the diease didn't spread as much.
First Strike: First known out break of element 115, out side of Germany (Russia)
Escalation: The scale of 115 is growing bigger around the world hence Call of the Dead. (Russia / Spreading further maybe the actors took it back to the US so moon could happen?)
Annihilation: Trying to get rid of the zombies around the world. You're tring to end the threat of zombies before it spreads further than it already has. But you're failing (Himalayers)
Resurrection: Meaning Samantha or maybe how the zombies are coming back for more like from the past (meaning WaW maps) You're baed in area 51. Then sent to the mon, Resurrection could mean that the zombies are still rising and can not be stopped. Thus why Richtofen wanted to blow up earth?
Revolution means fight against Maxis or Dr Richtofen.
You have to choose who to follow story wise, Maxis or Richtofen. You're revolting against them.
Uprising means the zombie hoards are fighting back against them.
It could mean who ever you didn't choose to follow is going to kill you, or it could be the zombies are starting to take over the whole world and time via the teleportes which sent group 935 back in time?
Vengeance: From who ever defied them (Maxis/Richrofen)
I haven't got this map pack yet (ps3) but what I make out it says someone is going to get revenge and kill someone, meaning if you didn't listen to Maxis maybe Samuel is going to die? Or maybe group 935 might pay the price, better yet Richtofen might kill Maxis or Maxis might kill Richtofen for locking him and his daughter in the teleporter.
So I spent a good few hours trying to think up some random ass ideas for this.
A lot of other people go with the F.E.A.R R.U.V.- part, but this could also mean something. Discuss?
