3D Model: Design A Sci-fi Enemy Drone Or Sentry Bot That Floats Or Hovers In Mid-air. It Has A Sleek, Futuristic Shell With Glowing Lights And A Rotating Core Or Eye. The Enemy Should Look Threatening But Does Not Need Limbs Or Movement Animations. It Can Fire Energy Blasts Or Lasers From Its Body Using Visual Effects. The Model Should Feel Alien Or Robotic, Ideal For A Sci-fi Action Game Where It Hovers Silently And Attacks Without Needing Animation
