About Gray Matter
Gray Matter is a mystery adventure about neurobiologist Dr. David Styles and street magician Samantha Everett. After a tragic accident, Styles becomes a recluse in Dread Hill House. Samantha arrives as he looks for a new assistant, and he gives her the task of finding six people to form “The Lamb's Club,” a group of human guinea pigs for his experiments at Oxford University.
The mystery
The tests begin innocently, but a chain of inexplicable incidents soon follows. As you investigate, you uncover questions about the true aim of Styles' research, the nature of reality and the power of the human mind, along with secrets that may cross over from the other side. The dark story is told in the style of a gothic novel across eight chapters.
Play as Styles and Samantha
