From the Introduction:
Howdy, partners! As you may know, you can play Deadlands in three completely different rules sets. There’s classic Deadlands, with all the chips, cards, dice, and six-gun zaniness you grew up on. There’s also that new-fangled D20 version with classes, hit points, and levels. Steve Jackson Games® even makes GURPS® Deadlands, for perhaps the most realistic version of the three!
But now Pinnacle has this new "Fast! Furious! Fun!" set of rules called Savage Worlds, and some of you have a hankerin’ to try it out on the Weird West. It’s only natural that you do, since Savage Worlds is based off the Deadlands miniatures game, The Great Rail Wars.
We’ve always been pretty proud of that game-it’s won every major award out there and still has a huge following despite our not being able to support it the way we originally set out to.
Now we’ve come full circle, and a lot of folks want to play both Deadlands and The Great Rail Wars with Savage Worlds, which has some nifty new tweaks from the experience of five years and thousands of players. In this book you’ll find rules for playing the Deadlands roleplaying game with Savage Worlds.
