The First-Person Shooter (FPS) is a popular game form, with examples appearing on many different platforms. The genre has an almost two decade history and is represented by hundreds of commercial titles. While there has been extensive study of the FPS genre, this has tended to focus on particular games, or at best a limited set of examples. In order to provide a wider context for such work this paper surveys 566 separate FPS titles, across a range of platforms. The titles are compared by year of release, platform and game setting. Characteristics of avatars within the surveyed titles are also examined, including race, gender and background, and how these vary across platform and time. The analysis reveals definite trends, both historically and by platform.
