Stealth Cyborg in Dark Underground Facility

Prompt:

Stealth cyborg with a fully armored chest, tiny red glowing eyes, human teeth, and a square jawline. A circular insert is on the side of its head, with wires and cables running through its chest cavity. Its chrome arms have articulated joints, and a thick spinal cord connects to the chest chassis. It grips a futuristic black assault rifle with a scope, firing laser projectiles. The scene is set in an abandoned underground facility with destroyed concrete, steel ruins, and buried junk cars. The atmosphere is dark and suspenseful, creating an intense, Terminator-style nightmare. Ultra-realistic, masterpiece quality.
