Creatures That Sing

CREATURES THAT SING expands the abyssal world of Beneath the Pressure with a new collection of rules, bestiary entries, and encounter systems built for those who still descend after the lights fail. This supplemental volume introduces over a hundred new entities, evolving habitats, and mechanical tools designed for deep-sea survival horror role-play.

Within these pages, players and game masters will find:
• Detailed creature entries divided by depth zone-from First-Depth predators to End-Depth horrors that rewrite the rules of physics.
• Expanded guidance on Predator Logic, Resonant Mutations, and Corruption Tracking, integrating biological terror with the core mechanics of Pressure, Flow, and Resonance.
• Systems for Depth Cards, Faction Briefs, and Black-Depth Trade, bringing new layers of strategy and narrative tension to campaign play.
• Optional frameworks for Leviathans, entities that are less monsters than living environments-gods of the trench whose existence alters every encounter.

Creatures That Sing treats every sound as a story and every encounter as a conversation with the ocean's will. Designed for use with the Beneath the Pressure Core Rules, this book functions as both expansion and interpretation-building on established systems while opening new ways to feel lost, hunted, and remembered.

For storytellers seeking tension instead of triumph, this volume transforms the deep into a living participant-part bestiary, part theology of pressure. Every creature here was once something that listened too long.
