The YouTube banner art features the iconic skyline of Bioshock's fictional city, Rapture, with its towering art deco architecture rising high above an underwater abyss. The skyline is set against a dark and ominous sky, with flashes of lightning illuminating the buildings and casting deep shadows. The game's protagonist, Jack, is shown in the foreground, wielding a wrench and bathed in a red glow that contrasts with the icy blue tones of the cityscape. The art style is reminiscent of 1940s classic noir films, with a surreal and dreamlike quality that perfectly captures the dark and twisted world of Bioshock.
