Call of Juarez: Gunslinger is a Western-themed first-person shooter video game, the fourth in the Call of Juarez series. Unlike its predecessor, Call of Juarez: The Cartel, Call of Juarez: Gunslinger returns to the traditional Old West setting and features three unique game modes (story, arcade and duel) while the setting is the life story of a bounty hunter named Silas Greaves.
