Style: A hybrid of industrial metal (Doom Eternal), dark ambient (Painkiller: Orphanage) and futuristic synthpop (Quake 4). Rhythm: dynamically changing: the beginning is 90 BPM, pulsating bass, rare beats, disturbing sounds of the shelter (creaking, ticking, distorted children's voices); fight — acceleration to 140-160 BPM: double bass drum (Doom Eternal), electronic beats and glitch (Quake 4), tremolo guitar riffs. Atmosphere (battle scene): gloomy and creepy: ghostly choirs, reverse reverberation on children's voices, toy melody in a lowered structure (Painkiller); Aggressive: heavy distortion guitars, metal screeching, explosions (Doom Eternal); cool and technological: arpeggio synthesizers, sequencer lines, industrial noises (Quake 4); dynamics: alternating dense sections and "dips" with residual ambient elements.
