This is Roswell Monopoly, in case you have figured that out yet - lol.
Orignally it was posted on a site called Rosopoly with everything you needed to play.
I thought I had I all saved, but I can't find any of it, and unfortunately the site is long gone.
I got this reproduction of the board out of the Crashdown Yearbook.
Perhaps some enterprising fan will attempt to recreate the rest of it or has it saved.
Please send it in if you do!
