Place it near the end of a match edit, after Enemy Spotted and before the final play, then follow it with Bomb Has Been Planted to signal the last objective before the closing push. Use it once as the turning point, not as background throughout the clip.

This short Halo Reach clip is the game's announcer voice saying '30 seconds remain' in a calm, clipped warning that lasts under two seconds. It creates a sudden sense of urgency, like a match is about to end and every move counts. The line comes from Halo Reach's multiplayer matches, where it marks the final countdown before time runs out.
