A first-person shooter (FPS) is an action video game from the shooter game subgenre. Like all shooters, they involve "an avatar, one or more ranged weapons, and a varying number of enemies". FPSs are distinguished by a first person perspective, that renders the game world from the visual perspective of the player character. The character is nominally a literal person; humanoid movement is expected. Games that primarily involve piloting vehicles are more correctly classified as vehicle simulation games.
In the modern era of video games, FPS was one of the first genres to use key technologies such as 3D graphics, online play, and modding. Enhanced realism combined with graphic violence has also made FPS a common topic in ongoing controversies over video games.
