There are plenty of things out there that go "bump" in the night.
... like my upstairs neighbor who seems to feel the need to walk around at all hours of the night doing god knows what...
But there are other things as well, like werewolves, vampires, and other spooky things that love to eat innocent bystanders. That's where the Rippers come in. I know, it seems like the Rippers would be something you'd fight against, but that's just not the case. The Savage Worlds book for Rippers Resurrected is in their last week over on Kickstarter.
This book continues on the adventures of the Rippers, originally released in 2005. However, you need not have played that campaign to use this one. It begins with the Rippers chasing after their old nemesis, the Cabal, but also learning about a new enemy that takes the form of an evil cult looking to restore power to an ancient evil (those things just never seem to stay away).
The campaign is over 11x funded and still has 6 days left on the clock if you'd like to get in on the action.
