How i think CoD: BO packs should and could work

I think that the packs could work like this: You get a Three Chapter mini-campaign, three multiplayer maps, A new weapon, New grenade, and one new zombie map. The campaigns can be finding woods. How Mason meant Hudson and/or Weaver. And the assassination of JFK. A new grenade can be the Bouncing Bettie or Molotov. The new zombie level would be unlocked by completing the campaign.
