An audio-reactive twin-stick bullet-hell where the song is the weapon. Play three curated packs with three megabosses, or import any track and the game builds a level from it: enemies spawn from onsets, bullets lock to the beat, your shots bloom in the song's key.

<h2 class="bb_tag" ><strong>THE MUSIC IS THE LEVEL</strong></h2><p class="bb_paragraph" >  SUBSØNIC is an audio-reactive twin-stick bullet-hell where every wave, every pattern, and every boss is built from the</p><p class="bb_paragraph" >  song you're playing. Enemies spawn on the onsets. Bullets quantize to the beat. Boss phases follow the track's own</p><p class="bb_paragraph" >  structure; the verse builds, the chorus swarms, the drop is a wall. Beat the song and you beat the level.</p><p class="bb_paragraph" >  </p><h2 class="bb_tag" >TWO WAYS TO PLAY</h2><p class="bb_paragraph" >  </p><ul class="bb_ul"><li><p class="bb_paragraph" ><strong>Curated packs</strong> — hand-tuned experiences shipped with the game, analyzed and balanced track by track.
