From the introduction: Impact Winter allows for touch as a gameplay mechanic. Before play begins, every player should discuss their comfort with physical touch. ... Impact Winter will utilize a form of sensory deprivation known as the Ganzfeld Effect. This effect requires a light source (a regular ceiling lamp should be adequate). A paper mask worn over the eyes will diffuse the light to create a uniform visual field and headphones playing white noise will create uniform audio input.
