You've seen Duke Nukem expansions in a beach on "Duke Carribean: Life's A Beach", Duke in Christmas on "Nuclear Winter" and even in the White House on "Duke It Out In DC". Now here is a new expansion known as "Duke Nukem: Halloween Mayhem". 
Alien demons are spreading through earth on the spooky month of October and Duke must take them out and save the world. 
New weapons, supernatural enemies and Halloween maps!
