Mars in Gamma World

[Ed the Coastie]

I've been doing some tinkering with my old Gamma World campaign with an eye to maybe running it again sometime. Knowing my current crop of players and their penchant for following an arc just long enough to take off at an odd tangent, I decided that I might want to put some thought into what is going on in space.

The moon is covered nicely enough for my purposes by the write-up in the new version of Legion of Gold, and I like my "Cloud Cities of Venus" too much to abandon that idea. But I ran into a snag when I began thinking about Mars.

I don't just want to file the serial numbers off of GURPS Terradyne or Transhuman Space. What I am looking for is more along the lines of Barsoom...but I am really having difficulty finding a suitable justification for it to be that way. So I was wondering if anyone has done Mars with the Gamma World treatment; my Google-Fu is not particularly strong right now.

Ideas?????

Thanks.
