About Deadly Obsession
Deadly Obsession is a psychological horror visual novel in which you play a protagonist who wakes in a dark, unfamiliar basement after being taken by an obsessed captor. As you interact with him, his affection blurs into control, and you try to escape or become caught up in his version of love. Your decisions shape the story, uncover hidden truths and emotional fractures, and lead to 19 possible endings, not all of them kind.
