Place it just before the danger appears on screen, then follow it with Enemy Spotted to name the threat and Danger Alarm to raise the stakes. Keep it early in a gameplay montage, ahead of a kill or objective clip, so the warning sets up the payoff that follows.

This is a 13-second League of Legends alert clip built around a sharp warning signal that repeats to get attention fast. It feels urgent and tense, like a call to look up and react before something goes wrong in a match. The short, insistent pattern is easy to recognise even in a noisy lobby, and it works as a quick signal rather than background music.
