First-Person Shooter
It's like you're right there, killing Nazis.

"Far distant eyes look out through yours."

The First-Person Shooter is a popular form of Action Game. Its basic style of play is exactly what the name says: the perspective is first-person, through the eyes of the player character, and the action revolves around shooting.

Contrary to popular belief, it's not always about shooting the first person you see.

This is a game genre that was first widely popularized by id Software, via Wolfenstein 3D and especially Doom.

It actually had two potential sets of progenitors: there were games with a first-person, but not quite 3D because it was rendered in discrete steps, view of the surroundings, typically a dungeon (such as Star Cruiser and Ultima Underworld), and which had sensible and consistent worlds, NPC interaction, relatively few artificial restrictions, plotlines, and puzzles. And then there were games such as Wolfenstein 3D, Gun Buster, Doom, and Duke Nukem 3D, which had full freedom of movement but used it solely to let you shoot everything and proceed to the end of the level.

Game designers went with the latter for a while, but as technology advanced, the genre has begun to shift towards having more interactive surroundings, setpieces, friendly NPCs, vehicle driving sections, physics-based puzzles, cover mechanics and RPG Elements with games like System Shock, F.E.A.R. or Half-Life.
