Ultra-realistic high quality game render, cinematic first-person perspective screenshot from Half-Life 3. The player holds a worn, detailed gravity gun in front, with scratches and orange hazard decals. In the distance, a massive towering Combine citadel covered in metallic plating, blue glowing conduits, antenna arrays and huge illuminated Combine insignia and lambda symbols projected on its surface. The city below is flooded, with alien biomass and debris scattered everywhere, burning wrecks, and distant drones flying. The sky is dark and stormy, radioactive green fog and lightning bolts in the background. Realistic hands wearing a damaged HEV suit glove holding the weapon. Advanced realistic lighting, detailed textures, volumetric fog, cinematic depth of field, photorealistic style, next-gen game graphics, no painterly or illustration effects, highly detailed and immersive.
