Saturnine Night is the last supplement to White Wolf’s Promethean: the Created game, and it’s also that game’s “science fiction supplement”, in a way. While Promethean is pretty weird to begin with, this book explores some “way out there” concepts for the game: machine creatures, artificial radioactive life forms, stuff like that. I like Promethean as a game; it’s possibly the most “indie” World of Darkness game so far, and this book is a great way to finish off the line.
It’s a fun mix of serious stuff and not. I mean… this book contains radioactive zombies! And it has those without going all zany about things. In fact, those radioactive zombies are actually quite creepy and not much at all “pulp”. Still, if you want to inject some more over the top elements into a Promethean game, or any WoD game as a crossover, this book has you covered. Artificial machine hive minds, rogue A.I.s and such are slotted into the Promethean paradigm, so they are in some weird borderland between straight scifi and supernatural weirdness. Very nice, especially if you wan to to throw some real curveballs at your players.
The treatment of radiation and its effects is fairly realistic (i.e. nasty) here. No Fallout/Gamma World “fun mutants” here, radiation usually just kills you (fast or slow) in various bad ways. Except when it gives birth to something else. And yes, you can play a radioactive artificial being, if you want. Good luck finding other PCs you can interact with, though…
The book also contains some ideas about running Promethean games in general, including some crossover ideas.
All in all, a great book. Even if you’re not interested in running Promethean, this book will give you lots of fun NPC/antagonists ideas for pretty much any (new) WoD game – assuming you want some really strange NPCs.
