Monstrous invasion over a ruined post apocalyptic city

A dystopian wasteland scarred by nuclear devastation, littered with the remnants of a once-great civilization, is beset by a terrifying, Lovecraftian invasion force of twisted, three-headed, tentacled monstrosities, their dark, retro-futuristic aesthetic reminiscent of vintage pulp magazine covers, as a traumatized humanity cowers in terror before the abyssal horror that threatens to extinguish their very existence, their shattered cities a grim testament to the futility of resistance against an enemy from beyond the stars.
