Darkwatch

Ever seen a vampire with a Stetson and a six-gun? Probably not, thanks to the vigilance of the ancient, secret organization called Darkwatch, which has existed since the dawn of history to protect us all from the evil undead. In this premier release from High Moon Studios, players take the role of Jericho Cross, a rookie Darkwatch agent in the Wild Western frontier. During a train robbery, the hero is bitten by a vampire. He gains some useful, supernatural powers, but he must vanquish the creature that infected him before he loses all his humanity and becomes a full-fledged vampire himself. Equipped with enhanced weaponry and a loyal, undead steed, Jericho sets out on a quest to find the vampire who bit him. Darkwatch boasts dynamic artificial intelligence that is affected by the player's in-game reputation, nonlinear story lines and mission progression, and precise first-person shooter gameplay featuring location-specific damage.
