I've had this on the shelf for a long time. The idea of making a Martian Terrain came after the collapse of the Lost Worlds Project, and fell into the category of trying to rescue the mod in parts: we had a Mars destination and lots of cool Barsoom units made for it, so I decided to try to import them onto a stand-alone map. Well, first that meant making a map of Mars, then figuring out where water would have been if Mars had oceans. The Barsoom Mod is still a work-in-progress (some of you saw previews of it in the now-defunct Workshop I had at Storm over Civ), but these biqs and terrain were the result of those first efforts. There are two biqs in the rar file, each a different map of Mars, using the same terrain files: "Mars", which is the map of Mars as it is, i.e., dry, and "Mars Wet", which is a map of mars with oceans and lakes. Neither map has trees, jungles, or marshes on it, but those pcx files are included so you can add them in the editor, if you'd like. Both maps include a 9x9 tile Mt. Olympus Volcano (seen in the banner and in a screenshot below), which is my pride and joy. It's assembled from the Volcanos file, so if you want to use this terrain with a different map, you'll want to switch the 'Volcanos' and 'Volcanos unreformed' pcx files, both found in the terrain folder. Also: I made 'cracked earth' rivers so that dry mars could have irrigation. I have to thank Rick FGS for his water and desert terrains, both of which I recolored for this map, and a particular thank-you goes to Ares de Borg, who found the perfect texture for the Martian 'grassland' for me one day a few years ago to kick this off. Pounder's extremely useful Canyon floodplains are also used on these maps. Known issues: there's a mismatch in the oceans that I spotted as I was uploading this (of course) - I'll fix and update that as soon as possible. I'll post the fixed file here. So, the download is HERE. enjoy. 4/13/14 Update: Updated craters, mtn forests, Mtns, Volcanos, and water files. See post #18 for more info. 4/19/15 Update: Tundra irrigation fix, alternative roads. See post #25 for more.
