BANG! The Valley of Shadows - first available only as BANG! Udoli Stinu in the Czech and Slovak Republic - is an expansion for the BANG! card game that includes eight new characters as well as rattlesnakes, tornadoes, ruthless "bandidos" and other threats for those fearless gunslingers who would dare enter the Valley of Shadows.

The cards in BANG! The Valley of Shadows are based on submissions from players in the Czech Republic, with design help from BANG! author Emiliano Sciarra.
