Duke Nukem 3D demo is one of the Duke Nukem series games that has such features that have not been attempted in a 3D game before. Some of them are a mine that can release laser beam that can be placed on any wall, a shrinker ray that can reduce your opponent to a size of a G.I.Joe when they become a foot fodder and underwater swimming while shooting outside players. The story is that when L.A. was overtaken by alliens, you, as Duke, were being abducted. After returning to Earth, you find another allien race to deal with. Duke, at that time realizes that sometimes innocent people have to die in the search to save Earth and sets out to take revenge.
