The Horror
Musical

[FIEND] is a parasitic puppet master — spreading through a decaying family entertainment center via living audio cables. It hijacks the animatronic band [KIELZOG], turning their music into a weapon against you.

The environment consumes itself through audio cables like overgrowth, with liminal spaces that shift based on sound. Every corridor breathes. Every note is a threat.

Follow the cat [VRIENDJE] into the darkness. Escape, help her, and uncover what FIEND truly is.

Meet KIELZOG

[KIELZOG] is always trailing in your wake — using their music to deceive you or give unintended hints. Hijacked by [FIEND], performing as puppets in a horror show with no exit. Each member demands a different strategy to defeat.

RUN

[DD]

Fast, chaotic, and easily distracted. Hear the rhythm building? That's him closing in — chasing every sound you make.

Gameplay Mechanic

Relies entirely on sound. Chases any noise — very predictable, but relentless once locked on.

[B-BACKER]

Silent. Brooding. Lurks in the shadows — you won't hear him coming, only feel the bass resonating in your chest.

Gameplay Mechanic

Sticks to the background. Hates sudden noises. The best way to avoid him is hiding, not running.

[GRAAFS]

Aggressive, destructive, unpredictable. His riff is his fury — few who've heard his solo have been seen again.

Gameplay Mechanic

Easily provoked and blinded by rage. Use that uncontrolled fury against him.

[VEIL]

Jealous, envious, attention-seeking, narcissistic. He craves your gaze. Look at him while he sings — or you die.

Gameplay Mechanic

If you look at him while he sings, he stays calm. Do. Not. Turn away.

The Music
System

FIEND Music System Architecture

The interactive soundtrack runs on two synchronized layers — a hybrid soundscape where music, environment, and enemy behavior are tightly integrated. FIEND's influence is heard as clearly as it is seen.

Digital Entity Layer (2D / Non-Diegetic): FIEND's signal processes the base synthesizer through distortion, modulation, and dynamic parameter changes — reflecting story tension and player actions in real time.

KIELZOG Layer (3D / Diegetic): Each band member operates as an independent audio node in 3D space. Their performance is controlled by FIEND via tempo, filtering, intensity, and rhythmic variation — a narrative-driven musical performance that bleeds into gameplay.

Synthwave

The FIEND soundtrack is a living score — horror-punk synthwave that bends and distorts as the story unfolds. Every track is composed as part of the interactive music system.

Each piece was built to breathe inside the game's reactive audio engine. Listen, and hear what FIEND sounds like.

Why FIEND?

FIEND occupies a unique position in the indie horror market — combining the genre tension of Five Nights at Freddy's with the sound-driven design of Hellblade, wrapped in a visual language inspired by LAIKA studios and 90s claymation horror.

The reactive music system is not a feature — it's the core mechanic. No other horror game makes the soundtrack itself the enemy.

  • Strong visual identity — instantly recognizable art direction
  • Unique hybrid music system with full IP ownership
  • Playable vertical slice demonstrates proof of concept
  • Clear target demographic: horror + indie fans, 18–35
  • Built on Unreal Engine 5 — scalable to full release
  • Claymation aesthetic differentiates from low-fidelity indie horror
  • Modular enemy system — each band member is a distinct experience
  • Horror-punk synthwave soundtrack with licensing potential
// Studio & Contact

FIEND is currently in vertical slice phase and seeking publishing partnerships, funding, and co-development opportunities.
