One DNA sample. Three suspects. Zero answers. An immersive cyberpunk thriller. No ads. No tracking. 100% Offline. One DNA sample matches three different people - all alive, all with alibis, all claiming they’ve never met. Dr. Saya Torres expected a routine homicide: blood spatter, DNA evidence, standard protocol. Instead, the DNA matches three living suspects, and the investigation exposes an underground system producing untraceable, disposable humans. ZERO SUBSTRATE is a forensic investigation experience built specifically for iOS - a narrative-driven application where interface, systems, and evidence analysis are part of the story itself. Set in San Francisco, 2027, it serves as a standalone prequel to the VOID conspiracy. --- INTERACTIVE FORENSIC EXPERIENCE ZERO SUBSTRATE is not an ebook or PDF reader. The story is delivered through a custom-built investigative interface designed as software, not pages. • Terminal-style investigative UI integrated into the narrative • Dynamic typography representing thought, dialogue, and forensic data • System-driven progression instead of static chapters • Interface elements that function as in-world investigation tools The app behaves like a forensic system you operate - not a book you scroll. --- FULL INVESTIGATION INCLUDED The complete experience is included with purchase. • 12 investigation chapters • ~200 minutes total experience time • ~40,000 words of interactive narrative content • Seamless progression across the entire case No subscriptions. No additional purchases. No accounts required. --- EVIDENCE SYSTEM You do not simply read events - you uncover them. As the investigation progresses, the system unlocks materials discovered by Dr. Torres: • Police reports • Audio logs • Crime scene records • Case evidence stored in a persistent Evidence Vault All evidence remains accessible for cross-reference at any time, turning the narrative into an evolving case file. --- SYSTEM FEATURES Designed as a native iOS application using modern Apple frameworks. • Automatic progress tracking with precise bookmarks • Reading analytics and completion statistics • Integrated investigation database • Completion certification after case closure • Instant resume exactly where you stopped --- PRIVACY BY DESIGN ZERO SUBSTRATE operates entirely on-device. • Works offline after download • No analytics or telemetry • No tracking frameworks • No ads • No accounts or data collection Your activity remains private and local to your device. --- ACCESSIBILITY • VoiceOver fully supported • High contrast visual mode • Reduced motion support • Adjustable animations and haptics • Dynamic Type support --- LOCALIZATION Full Japanese localization included.
