Deadlands is a genre-mixing alternate history roleplaying game which combines the Western and horror genres, with some steampunk elements. It was written by Shane Lacy Hensley and published by Pinnacle Entertainment Group.

The eight-times Origins Award-winning setting has been converted to many other systems over the years and is available in the original Classic Rules, the revised Classic Rules, d20 System, GURPS, as well as a Savage Worlds version called Deadlands: Reloaded. (Wikipedia)
