From AionSource.com Wiki
A first-person shooter (Commonly called 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". But FPSs are distinguished by a first person perspective, that renders the game world from the visual perspective of the player character.
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.
