Dark ambient industrial sci-fi stealth, motion sensor sound design elements, irregular heartbeat pulse, deep sub-bass drones, minimal percussion, glitch textures, high tension atmospheric underscore, realistic space station threat detection vibe, immersive background score, BPM: 92 (irregular pulse feel)

[Intro – 0:00–0:45] [Low sub-bass drone with slow modulation] [Soft electrical crackle] [Single distant sonar ping] [Very faint mechanical hum, slightly detuned] (After 20 sec) [Short digital beep — like motion sensor activation] [Silence gap] [Another beep, slightly closer in stereo field] [Stealth Pulse – 0:45–1:40] [Muted heartbeat-style low kick enters, irregular timing] [Thin high-frequency tension tone sustained] [Subtle metallic ticking rhythm, not steady] [Low filtered noise sweep passes behind stereo image] [Detection Build – 1:40–2:40] [Sensor beep becomes rhythmic but uneven] [Low distorted bass pulse syncs loosely to beeps] [Glitch artifacts appear briefly then cut out] [Short reversed metallic impacts] [Very quiet rising tone underneath everything] [Contact Unconfirmed – 2:40–3:20] [Beat drops out suddenly] [Only drone + echoing sensor pings] [Subtle scraping metal sound moving left to right] [Deep distant impact — ambiguous origin] [Threat Escalation – 3:20–4:20] [Heartbeat kick returns, slightly faster] [Low industrial percussion, sparse but heavier] [Sensor beeps now sharper, more urgent] [Short alarm fragment that cuts off abruptly] [Heavy bass swell every 12 bars] [Final Section – 4:20–5:00] [All rhythm strips away] [High ringing tone builds tension] [Rapid triple-beep warning] [Sudden deep impact hit] [Hard cut to silence] (After 2 seconds) [Single distant motion ping]
