The main protagonist is once again Detective Sebastian Castellanos. This time, he is given the chance to uncover new secrets and face even greater, unexplored threats when his daughter, Lily, is trapped in another world—the world created from the minds of people, familiar from the events of the first game. Lily was placed into the STEM system, a mysterious technology that connects the human mind to an artificial reality. During the project’s development, a failure occurred, and the STEM world absorbed countless souls, creating distorted and horrifying realms. Sebastian must save his daughter, but to do so, he must confront the nightmare and those behind it once again.
