Instrumental high-intensity dark industrial cyber-metal / breakcore video game soundtrack for an extremely brutal futuristic sci-fi action game boss fight.

Create an aggressive, chaotic, mechanical and relentless track with an extremely high energy level. Tempo around 180 BPM. Combine heavily distorted electric guitars, crushing industrial percussion, rapid breakbeats, blast-beat-inspired drums, distorted sub-bass, aggressive synths, dark atmospheric drones, metallic impacts, glitch textures, harsh electronic stabs and mechanical sound-design elements.

The overall atmosphere should feel brutal, violent, oppressive, frantic, futuristic and dangerous — like fighting a gigantic heavily armored war machine in a dark industrial sci-fi environment. The music should constantly maintain tension and forward momentum, with almost no downtime.

Use complex syncopated rhythms, rapid drum fills, constantly changing guitar riffs, aggressive bass patterns, distorted synth accents, metallic hits and short tension-building transitions. Introduce evolving variations throughout the track so it remains interesting during prolonged gameplay without becoming repetitive.

Do NOT create a conventional song structure with a clear intro, verse, chorus, breakdown and outro. Instead, create a continuously evolving circular combat arrangement designed specifically to play indefinitely during gameplay.

IMPORTANT: This must be a PERFECT SEAMLESS LOOP.

The track must have NO audible beginning or ending. Do not use a fade-in, fade-out, silence, final chord, final note, final hit, cymbal crash, musical resolution, dramatic ending or any other indication that the composition has finished.

The first and last sections must be musically interchangeable. The opening 4–8 bars and final 4–8 bars should share the same key, rhythmic pulse, harmonic tension, tempo, atmosphere and important musical motifs. The final musical phrase must naturally lead directly back into the opening phrase.

Use a circular structure such as:

A → B → C → D → C → B → A → A

where the final A seamlessly connects to the first A.
