Therefore, the Game Master can tailor his campaign to suit his player group. Depending on the type of mission, the gameplay can involve investigation, combat, intrigue, or a number of other genres. The players assume the role of a group of Acolytes working for an Inquisitor, who sends them on various missions. In Dark Heresy, the player characters are agents of the Inquisition.
