Details

Prepare to descend into a meticulously crafted hell in THE ILLUSION: NIGHTMARE, an adventure game from Raven Games that plunges players into the depths of psychological horror. You step into the shoes of Martin, an investigator who stumbles upon a secret cult and finds himself imprisoned within Zorya's mysterious mansion, known only as 'The Nightmare.
