|Conveying guidance through the voice of disembodied or remote entities.|
One way to provide the player with aid while playing, regarding the gameplay but also dynamic notifications (Awareness for a critical state, for instance), is to design a Helper Voice who provides such information through Dialogue in a diegetic way.
Helper Voice may indirectly contribute with pieces of Narrative but it is different from Narrator. While Helper Voice provides information about the gameplay, i.e. about what to do or how to do it, the Narrator tells the story of the game.
The Helper Voice is sometimes "a voice from above", frequently conveyed by a reverberated Dialogue and possibly some additional Sound Effects that approximate it from the archetype of the voice of fantastic or divine entities.
Yet, perhaps the most commonly designed solution for the Helper Voice is to have a NPC in a remote location providing information over a communicator. The same channel and character is often used to provide Narrative (in which case such character also behaves as Narrator).
