Asterion is an interactive work which is freely inspired by one of Borgès’ short stories called “The House of Asterion”. It offers the player to live a loss of territory through the death throes of the narrator. The purpose is to use elements of the videoludic grammar, such as a combat system of hand-to-hand fight, as well as sound and visual experiments in order to give the player the feeling of being invaded in his private world. The camera is in first person and the vision and the point of listening of the player correspond to those of the avatar. The system of control gets closer to classic First Person Shooter. The player can move with his keyboard and use with the mouse button activating the narrator’s terrifying hand.
