I'm working on a new post apocalyptic campaign and I've drawn out some of the old post apocalyptic 1970's classics below are some of the old science fiction classics. While there are supposed to be five. You can't have a list without the William Nolan classic Logan's Run!
Planet Of The Apes 1970
Beneath The Planet of The Apes 1970
The Omega Man 1971
Damnation Alley 1977
Logan's Run 1975
