About this project
What does Hollow Signal add?
📡 Hollow Signal
"This concludes the emergency broadcast. If this message continues, the voice you hear is no longer ours."
Hollow Signal is an immersive psychological horror audio and visual expansion pack designed specifically to complement the terrifying mechanics of the Schism Protocol mod.
When your sanity drops and the entity begins abducting players to replace them with skin-wearing Husks, the entire emergency infrastructure collapses. Hollow Signal intercepts the world's communication frequencies, forcing regional broadcast alerts to dynamically morph based on the biome you are desperately trying to survive in.
⚙️ Core Features & Mechanics
- ☀️ The Temperate Zones (U.S. EAS Format): While exploring warm or temperate biomes (Plains, Deserts, Forests), your receivers intercept the classic, harsh U.S. Emergency Alert System. It features the iconic 853+960 Hz analog screech and clinical law enforcement directives warning of a hostile intrusion threat.
- ❄️ The Boreal Sectors (Canadian Alert Ready Format): Crossing into freezing, sub-zero climates (Taigas, Snowy Tundras, Frozen Peaks) automatically shifts the broadcast infrastructure to the Canadian digital tri-tone pulse. It utilizes modern, localized public safety alerts to heighten the isolation of the frozen wilderness.
- 👁️ The Husk Interference: When a Schism Protocol entity closes in, the signal corrupts. The text blocks glitch, the rules give terrifyingly contradictory commands, and the automated text-to-speech voice begins addressing your location directly.
⚠️ Public Safety Protocol
- Maintain Structural Barriers: Lock all doors, draw the curtains, and stay away from windows.
- Ignore Auditory Stimuli: If you hear footsteps or the voice of a teammate calling from outside, do not open the door to confirm proximity.
- Signal Deterioration: If the repeating broadcast suddenly alters its text formatting, switches dialects, or changes tonality, immediately disconnect the receiver. The system has been compromised.
