A gigantic futuristic race track set in a sprawling sci-fi megacity, with massive loops, vertical climbs, anti-gravity sections, sharp turns, and suspended platforms high above a glowing urban landscape. The track is detailed with neon lights, holographic signs, metallic textures, and dynamic lighting. Scale is enormous—track segments should be wide enough for large high-speed vehicles. Include bridges, tunnels, jumps, and multiple elevation levels. Stylized for a high-intensity racing game like Wipeout or F-Zero.
