From publisher blurb: "A scoutbot has returned with video files of this red desert planet, showing what appear to be a number of small mud cities and a network of canals linking them. In its 20-hour slip it managed to map most of a single tridrant in the south (roughly 1/20th of the planet’s surface), and spent several hours on the surface unmolested while running a spectroscopic analysis. According to the bot’s findings, the planet’s atmosphere is thin but breathable by humans." Travel to the Red Planet as envisioned by Stanley Weinbaum in the classic story A Martian Odyssey. The PCs find themselves wandering the inhospitable and alien landscape of old Mars, encountering its most deadly - and most intriguing - life forms. THE MARES OF MARS is a DayTrippers adventure module from the GOLDEN AGE ADVENTURES anthology. If you have that book, you don't need this one. DayTrippers uses a descriptive scale which can easily be converted to other game systems. Conversions are included for 2-12, 1-20, PbtA and percentage-based systems.
