At just under three seconds, this clip is compact and usually needs no trimming. Its sharp alarm tone cuts through music easily, so lower it when dialogue or narration is playing. Download the MP3 to keep it available offline or import it into your preferred editor. Most phones can use the file as a ringtone or notification tone after it is saved in the appropriate audio folder. For a second dramatic cue, a Metal Gear alert pairs naturally with the siren without extending the sequence too far.
