This is v1.0 release of the SHADO Moonbase from Gerry Andersons UFO TV Series from the early 1970's.
I've also included an additional Base called - Marsbase-Straker, which is made from the parts of the the Moonbase, plus a couple of other pieces.

Some scenarios require you to download some additional add-ons from this site. Please read the included documentation for more details.
