P.U.L.S.E.
Cosmic Horror Narrative RPG
$0.99 · Designed for iPad. Not verified for macOS.
Every choice echoes. Every shadow remembers. Dark entity crafts your cosmic horror story in real-time — no two investigations are ever the same.
Every story is yours alone.
P.U.L.S.E. — Prophecy Unveiling Lost Spectral Entropy — is an AI-driven narrative RPG set across the shadowed cities of the 1920s. No two playthroughs are alike. Every passage of text, every atmospheric illustration, and every word of voice narration is generated in real-time, crafting a cosmic horror tale that exists only for you.
SPIN THE REELS OF FATE
Your destiny begins with three spinning reels — a slot machine selects your Location, Profession, and the Eldritch Entity that stalks you. A jazz musician in Prague hunted by something that lives in mirrors. A war photographer in Shanghai pursued by a god that devours memory. The combinations are endless.
A LIVING STORY
An AI Game Master weaves your narrative through an 8-stage Story Circle. Make choices. Type your own actions. Investigate, flee, fight, bargain with things that should not exist. The story responds to everything you do — there are no pre-written paths.
FULL VOICE NARRATION
Every word is spoken aloud by an on-device narrator whose voice shifts with the mood — measured calm in quiet moments, rising panic as the entity draws near. No internet required for voice.
ATMOSPHERIC ART
Each scene generates a unique ink-wash illustration in the style of 1920s noir photography. Watch the world materialise as you read.
THE ENTITY HUNTS YOU
As turns pass, the eldritch presence grows stronger. Subtle wrongness becomes undeniable horror. Your Vigor and Sanity erode. Will you uncover the truth and survive — or join the ranks of the Silent Extinction?
SILENT EXTINCTION
Death is not a game-over screen. It is a period newspaper obituary. A commitment notice to an asylum. A name forgotten by everyone who knew it.
