The Endymion is a stand-alone survival-horror adventure for d20 Future. It is set in the quasi-near future aboard the starship Endymion, a massive exploration and excavation vessel setting out on its maiden voyage to the mining outposts on the moons of Jupiter. Its mission includes both commercial and scientific goals.
Only human is available, but see genetic manipulation in the technologies section, below. So far, no alien life has been encountered.
Advanced classes from the core book are available except the Shadow Slayer, Occultist, and Acolyte. Classes from d20 Future are available except for the Helix Warrior, Mecha Jockey, and Xenophile, though many others such as the Tracer would be poor choices, despite being available.
