a.Shooter – Sonic Invaders, by Austrian collective a.Game (Michael Aschauer, Josef Deinhofer, Thomas Felder and Rainer Mandl) is a solely acoustical ego-shooter game referring to the classical form of interaction in the game Space Invaders.
Wearing headphones and using a joystick, the player has to shoot up sonic invaders conquering a virtual room as defined by panorama, pitch and volume. Starting with a simple hear-and-match mechanism, the advancing levels transform it into a tonal and musical interaction game.
