This five-second clip is the distorted, electronic death cry of a Metrocop, the masked robot police unit from Half-Life 2, collapsing into static and a low mechanical groan. It feels abrupt, tense and darkly comic, like a patrol going wrong in a single beat, and it works best as a sudden defeat sting rather than a long dramatic moment.
