Doomtown is an expandable card game based on the Deadlands role-playing game. It was originally a collectible card game that ran from 1998 through 2001, published by Wizards of the Coast (WotC) under license to Pinnacle Entertainment Group until January 2000, when WotC quit production and the license transferred to Alderac Entertainment Group; its last expansion for many years was Do unto Others from 2001. In 2014 the game was revived with updated rules and sold in non-randomized expansions.
