Selected works spanning game soundtracks, dark ambient scoring and experimental sound design.
Game soundtracks, dark ambient scoring and experimental sound design by Nyel (Natal Castro) — from sci-fi combat and horror to open-world RPG.
A top-down tactical space combat game where every shot counts. The original soundtrack by Nyel (Natal Castro) trades horror for cold sci-fi electronics: pulsing synth layers, industrial percussion and a constant sense of pressure built for focused warship battles.
An open-world RPG with deep simulation systems — dynamic NPC routines, reputation mechanics and directional combat. The OST covers the full emotional arc of the journey: main menu, day/night exploration, combat escalation and quiet wandering.
A sandbox war simulation where players design and participate in large-scale battle scenarios. The soundtrack moves through orchestral tension, industrial percussion and shifting battlefield dynamics — from quiet preparation to chaos and aftermath.
A first-person horror adventure where the player escapes a haunted mansion — and the creature can hear you through your microphone. The OST builds sustained dread through dark textures, unsettling ambiences and moments of sudden silence that hit harder than any jump scare.
Dark atmospheric ambiences, game & film soundscapes, covers and original compositions — sometimes using in-game visuals to build fully immersive audio experiences.
Hardware synthesizers, live sessions and musical explorations — working with real instruments, not just screens.
