Generated from: Game asset concept: the central citadel of a modern military fortress, an imposing octagonal concrete citadel about 44 m across and 26 m tall, light grey weathered reinforced concrete, thick battered walls with a ring of gun embrasures, a tall central observation tower with a dark glass command deck and a radar mast, a red-and-black command banner. Bold, simple, heroic silhouette. Realistic, seen from a 3/4 high aerial angle like an RTS game, single isolated object centred on a plain white background, no ground, no people.
