This article examines how nuclear weapons are depicted in video games. While the literature has explored the social and symbolic meanings of nuclear weapons and how they have been represented in popular culture, existing accounts have not thoroughly engaged with video games. Examining the bestselling game Call of Duty, I show how gameplay narratives contribute to normalising dominant knowledge about nuclear weapons. The overarching argument advanced in this article is that representations of nuclear weapons in video games contribute to legitimising the ongoing possession and modernisation of nuclear weapons. Drawing on feminist post-structuralist theory, I show how nuclear weapons are programmed to be an exclusive item that only the most skilled players can obtain, reinforcing the exclusionary power dynamics sustaining the nuclear status quo. Moreover, I show how game dynamics produce nuclear weapons as a win-condition, and thus a symbol of power and success that reinforces dominant understandings of their military value while masking the horror of killing. Deconstructing the playing dimension of video games, I situate the ludic aspect as a meaning-making system, working synergically with gameplay stories to reinforce dominant knowledge about nuclear weapons. Ultimately, the article draws attention to everyday discursive mechanisms that render a nuclear world possible.
