I thought I would add this: Deathlands first came out in 1986. At about that same time, there were several other series along similar lines:
Doomsday Warrior by Ryder Stacy
Endworld by David Robbins
The Guardians by Richard Austin
Survivalist by Jerry Ahern
Ashes by William W. Johnstone
Anyone know of any others?
I never had the opportunity to follow any of those. In the area where I lived at the time, the books were very hard to
find. Deathlands was the only series that I was able to follow and never miss a volume. And that was only because
I ordered many of them direct from Gold Eagle, rather than relying on book stores and their hit-and-miss ways.
I can say that the first volume of the Doomsday Warrior series was quite good.
