"Every time I start on a new project I really want to find some kind of distinctive, original sound," Anderson told Gamasutra. "Not like a musical style, more like a sound quality that you can associate with that project. I think it helps to create a sort of holistic, whole experience." The human skull created an "iconic signature," Anderson argues, which would have been difficult to replicate with muic software alone. The teeth, for instance, made small vibrations that should sound "unsettling, but also strangely familiar" to the player. Overkill? Maybe, but Anderson says such a "detour" can be necessary to create something truly new and unique.
