The Outlaw expansion has a very limited print run and was made available to backers of Dark Horse on Kickstarter.
This mini expansion adds a unique Special Role called the "Outlaw" to the game. This role may come into play when a Jail Action is triggered, with a player successfully rolling a die to escape the scene of the crime. Once claimed, the Outlaw special role will have an interesting ability that allows a player to use the result of a rolled black die to bump opponents off already claimed actions. This powerful ability is kept in check by the owner of the Sheriff role having the added ability to use the result of a silver die to capture the Outlaw player who then loses the special role and must spend the remainder of the turn sitting in Jail.
This expansion gives players a teaser of some of the mechanics that will be added to the pending full box expansion for Dark Horse.
