The game combines the supernatural with mundane reality, with campaigns often set in the modern world. Supernatural characters take on a human (or other mundane) form to further their various agendas. Although individual campaigns can focus on combat or direct conflict, Heaven and Hell settled into a Cold War called the "Great Game". Angels and demons typically struggle indirectly, by attempting to draw humans closer to their respective sides. Open hostilities are costly, and, in the game setting, rarely prove to be the most efficient option. This allows "In Nomine" to have the qualities of a morality play as well as those of a more standard role-playing game.
