Create an original cinematic deathcore track with claustrophobic sci-fi horror atmosphere. Open with spaceship ambience, ventilation hum, distant radio static, and a slow sonar pulse. Build from tense, quiet passages into crushing low-tuned guitar riffs, precise blast beats, deep growls, sharp screams, and massive half-time breakdowns. Add a dark melodic clean-vocal chorus for contrast. Use sudden stops, mechanical rhythms, and dissonant textures to suggest a creature moving through the ship. Keep the English lyrics clear and intelligible. Aim for polished studio production: tight drums, defined guitars, controlled low end, clear vocal separation, and strong dynamics. No muddy mix, unwanted noise, clipping, or excessive effects. Original composition; do not imitate any specific artist or soundtrack.
