(masterpiece, ultra-realistic, 32k, hyper-detailed, best quality, cinematic lighting, volumetric light, photorealistic, film grain, gritty texture) Brutalist post-apocalypse on an alien world. Sky choked with ochre and charcoal storm clouds, dim amber sun bleeding through. Crumbling massive concrete monoliths and skeletal megastructures jut from a cracked, ash-covered wasteland. Rusted rebar and broken slabs litter the ground. Amid this ruined sprawl, a colossal spider-tank stalks forward — a multi-legged armored behemoth, plated in scorched black steel, covered in brutal weld lines, exposed cables, angular harsh geometry. Its multi-terrain rotating turret bristles with heavy auto-cannons, rotary plasma launchers, and sensor dishes scanning the horizon. Hydraulic legs crush debris beneath, sending up clouds of gray dust. Faint orange industrial lights and grim golden runes pulse along its hull, tangled with cybernetic conduit lines. Foreground littered with twisted metal, old propaganda banners, charred bones. Midground: shattered brutalist towers loom, casting long jagged shadows. Background fades into storm haze and crumbling alien spires. Volumetric shafts cut through swirling ash, catching drifting embers. Cold, oppressive atmosphere.
