A technique where a player has a ''shadow'', a person that follows the player around and can interact on an ingame[[in-game]]-, and/or meta-level with the player. This ''shadow'' can for instance portray a players conscience or voices in the players head (and as such the shadow does not exist to other players), or could be something semi-''real'' like a posessing spirit or guardian angel (and then the shadow may or may not exist for other players).
