Place it right after a calm shot of a finished base, with Enemy Spotted just before it to show the intruder arriving, then follow with Danger Alarm Meme Sound once the damage spreads, so the sequence moves from discovery to full chaos.
このサウンドについて
This is a two-second Team Fortress 2 voice line from the Engineer, shouting that a Spy is disabling his sentry gun. The delivery is urgent and irritated, with a burst of panic that makes a setback feel suddenly serious and a little ridiculous. It comes from Valve's 2007 class-based shooter, where the line plays when a Spy's sapper attacks the Engineer's turret.
