A new anthology of first person shooter studies is out in the Continuum game studies series:
“The second volume of Continuum’s Approaches to Digital Game Studies series, Guns, Grenades and Grunts gathers scholars from multiple disciplines to bring the weight of contemporary social theory and media criticism to bear on the public controversy and intellectually investigation of first-person shooter games. As a genre, FPS games have helped shepherd the game industry from the early days of shareware distribution and underground gaming clans to contemporary multimillion dollar production budgets, Hollywood-style launches, downloadable content, and worldwide professional gaming leagues. The FPS has been, and will continue to be a staple of the game market.”
