Shadow Fight 2 is a martial arts fighting game released by Nekki in 2014 for mobile platforms, known for its silhouette art style and weapon based combat. Each round opens with this gong strike alongside the on screen fight prompt, so millions of players associate the hit with the moment control returns and the opponent moves. Clips of gameplay and short form edits later carried the sound beyond the game, where creators reuse it as a universal shorthand for a duel starting, even when no Shadow Fight footage is shown.
