The Senton Splash Tunnel is a concrete passageway underneath the town of Santa Destroy in the video game No More Heroes. During protagonist Travis Touchdown's time ranked sixth in the United Assassins Association, countless bloodstains blemish the concrete streets of Santa Destroy, which lead to the bloodied body of an unidentified girl in the barren Atomic Drop Ward, next to the entrance to the Senton Splash Tunnel. Touchdown follows the path, where he is taunted by a shadowy figure as well as several thugs.
