This is a brief, sharp impact from Half-Life, a single blow landing on a creature during combat. The sudden thud feels tense and jarring, like a close encounter turning violent in a dark corridor. It comes from the game's creature combat, giving listeners an instant jolt of danger without any dialogue or music.
