I think most people want New York City to be the next 7D2D.
-Skyscrapers, Sewers and Subways, oh my!
-Zipline from one skyscraper to another.
Your character, copied from 7D2D part 1 (you'll need it), starts out on the New Jersey side of the Lincoln Tunnel. There's a small, slowly growing settlement, set up at the park near the tunnel opening. They say someone or something has blocked the tunnel. Clear the tunnel and reach their scouts in the Hell's Kitchen Borrow.
New York is mostly overrun with zombies, rumors abound about the JFK airport and everyone says don't go underground if you want to live!
Or something.
