 Duke Nukem returns to his platforming roots in this throwback to his earlier games. This time, Duke fights his way across New York city s towering skyscrapers and through its gritty subway stations on the hunt for power-hungry villain, Mech Morphix. Mutants of every kind are thrown at Duke as he chases Morphix through eight large environments and avoids the green slime called GLOPP that s the cause of all the chaos.
