User blog comment:Drkdragonz66/Black Ops II - 8 Players and Zombie Story Mode hinted/@comment-1854594-20120504050606

I had the story mode idea myself. Only used it in one of my fanon maps on Nazi Zombies Plus though. Basically, the opening room had too options, one where you were supposed to follow the main antogonist of the storyline I crafted, or where you'd try and escape the facility. Trying to escape would present you with standard survival, while trying to catch the antagonist would have a campaign level-like set-up, and after completing would reward you with access to the final map in the storyline, which was a boss battle.
