THE MUSIC IS THE LEVEL
 SUBSØNIC is an audio-reactive twin-stick bullet-hell where every wave, every pattern, and every boss is built from the song you're playing. Enemies spawn on the onsets. Bullets quantize to the beat. Boss phases follow the track's own structure; the verse builds, the chorus swarms, the drop is a wall. Beat the song and you beat the level. YOUR MUSIC VIDEO IS THE NEXT LEVEL Drop in an mp4 or mov and SUBSØNIC pulls the song, builds the entire level from it, and plays the video behind the fight. You're not fighting to your favorite music video anymore; you're fighting inside it. THREE WAYS TO PLAY Curated packs — three hand-tuned packs shipped with the game, analyzed and balanced track by track, each building to its own megaboss. Plus bonus tracks for free play. Press play. Bring your own music — import mp3, flac, wav, or ogg. SUBSØNIC analyzes it offline in seconds, detects its key and structure, and turns it into a playable bullet-hell stage. Your library becomes the game.
 Bring your own video — import mp4 or mov. Same analysis, and the video itself becomes the battlefield backdrop.
 SHOOT IN KEY SUBSØNIC reads the harmonic key of whatever is playing and tunes your fire to match. The whole screen blooms in time; austere vector geometry, heavy bloom, reactive to the mix. It is loud, clean, and built to be watched as much as played. BUILD YOUR RUN Draft pick-1-of-3 SOUNDCHECK upgrades between songs, stack beat-locked powerups, and grow a tail that is both weapon and wall; wrap enemies Tron-style and nothing gets out. Survive UMBRA, the anti-bloom darkness that inverts the game's light. A live destruction meter rides above your ship, from WARMING UP to ANNIHILATION. EARN THE GRADE Every run is scored. Chase the S-rank, clear a stage without taking a hit, earn per-song medals, and push three packs of escalating intensity toward their finales: three distinct megabosses, each one a fight tuned to the song behind it.
