The headshot burst into the cultural imaginary with the assassination of John F. Kennedy in 1963, and it has been remediated from historical anxieties about execution and brain death to the eye-popping spectacle of the exploding head to video games, where it has entered a regime that holds virtuosic reflexes as the highest form of capital. By examining the textual and technological history of the headshot, this article develops a theory of mechropolitics: a way of thinking about political death worlds as they operate in the mechanics of video games and digital simulations. Moving beyond questions of whether violence in video games has a direct effect on aggression, mechropolitics mobilizes aesthetic and social justice critique to unmask the affective structures operating within digital death worlds. These prioritize twitch reflexes and offer few consequences—precisely the scenarios that render events like police shootings both legible and likely.
