Zombie Crew still had a lot to do with Alcatraz Island. Since they're working their asses off on DLC3 and DLC4, which btw will be releasing soon, they would've gotten the Campaign Crew, who had plenty of time on their hands, to make the map, but they would've given them outlines on what they wanted to include in the map.
