Duke Nukem is back with new weapons, more enemies, and one-liners. Set in New York City, Duke Nukem: Manhattan Project follows Duke as he battles his way across towering skyscraper rooftops and through gritty subway tunnels in the hunt for power-hungry villain Mech Morphix. The game throws mutants of every kind at Duke, including PigCops, as he chases Morphix through eight expansive environments and avoids GLOPP, the green slime that is causing all the chaos.
