SWhat happens when ancient evils awaken in the year 2085? One seriously f-ed up RPG campaign setting. The world of CthulhuTech revolves around the Aeon War, an ongoing struggle between hideous aliens, otherdimensional horrors, freaky cultists and vast conspiracies. And they all have battle tanks and giant mechs. But the core rulebook wasn't enough to describe this dark future, so Vade Mecum: the CthulhuTech Companion delves even deeper into this world of sanity-destroying rituals and twisted technology.Vade Mecum is a 160-page hardcover book with full-color art. And the art is amazing, really helping to evoke the gloomy, decadent world of CthulhuTech. This is definitely not a game for young children (if you couldn't tell by the cover). Further enhancing the "futuristic Lovecraftian" atmosphere are seven short stories, so there's plenty of backstory to flesh out your campaign (so to speak). For more hardcore gamers, there's plenty of crunch for the $39.99 cover price, including, "more than a dozen new unspeakable horrors, including the option to portray corpse-eating ghouls as Characters." I'm not sure anything else in the book will top that, but it also has over 20 new "machines of death," a bunch of new magic rituals, a system for psychic powers, and three new professions. It could be interesting to play a Zoner, a character who starts out insane. Or perhaps you'd prefer portraying the lovechild of a human and an otherdimensional being. There are detailed fighting trees that allow you to chain together certain moves for devastating attacks, and those attacks can target specific body parts with the hit location chart. It's all fun and games until someone suffers a "Genital Injury." Ow. Apparently, the CthulhuTech core book has been selling very well (the first printing sold out), so if you're looking for an RPG that's quite a bit darker than the usual swords and wizards affair, there are some kindred spirits out there.
