¶ Description
Don't Open the Door is a psychological survival horror game that explores the intersection of fear, desire, and body horror in a world irrevocably altered by the RAG-Virus.
The world has fallen silent, but the knocking never stops. The RAG-Virus has rewritten reality itself—a pandemic causing not just rapid weight gain, but something far more insidious. As Sarah, alone in her apartment, you'll face nightly Visitors. Some whisper desperate pleas for sanctuary. Others offer honeyed promises of pleasure and transformation. But in this new world, humanity wears thin masks that crack at the edges, revealing the hungering things beneath.
Features:
- Dual-Layered Horror: Surface-level survival horror masks deeper psychological terror about identity and desire
- Visitor Testing System: Check hands for subterranean soil, teeth for viral biomarkers—miss one detail and you're already infected
- Progression: Watch your character physically and mentally transform based on exposure and choices
- 8 Unique Visitors: Each with their own tragic history, dark secrets, and unknowable agendas
- 6+ Endings: From hopeful survival to blissful damnation, with multiple secret endings
- Psychological Seduction: Experience the slow, sweet pull of giving in to what you fear most
- Resource Scarcity: Limited energy for testing forces brutal triage decisions
- Environmental Storytelling: Apartment changes reflect your mental state and viral exposure
