Mars?a dying planet, still far from dead! In the vast steppes, in the sand of equatorial deserts, on the mountain tops, at the icy poles, in the massive artificial canals and in the ancient sewers of Martian cities, underneath the dry dust of Mars? surface, and in the wide open of the cloudless skies: the Martian flora and fauna thrive everywhere and have managed to adapt to even the most unfavorable of environments. Expand the game?s atmosphere by including herds of grazing eegars, a lens beetle lamp, or a tasty krolik dish with all six legs still attached. Confront your players with challenging combat encounters with a teshuwaan, a dust kraken, or even the legendary white ape. Alternatively, add some flavor to your game by having the adventurers participate in a gashant race or ambush them with a Deimos crawler?the deadliest weapon of the Worm Cult. This sourcebook contains descriptions and stats for more than sixty Creatures of Mars, for every purpose imaginable!
