If you're watching the live reveal of the new Google streaming service known as Google Stadia, you might have missed a reference to one of the most beloved and well-known "secret" codes of all time. During the presentation, when the buttons on the new controller were being shown and their functions explained, the on-screen graphic turned the controller to reveal the Konami code printed below the built-in microphone and audio jack. If you're somehow unfamiliar with the U,U,D,D,L,R,L,R,B,A, Start code, it's also known as the Contra code or the 30-lives code, among other names.
