Have you ever wanted to travel to Mars and take a portal to hell so you could kill the damned with a shot gun? If so Doom has your number. Made by id Software, doom is the seminal first person shooter. There were earlier shooters that made an impact, such as Wolfenstein 3D (1992), and there were shooters that advanced the genre more dramatically, such as Hovertank 3D (1991), but Doom was the game to excitingly deliver all the elements that would come to define the FPS genre in the coming decades.
It had tight controls, a dramatic setting, tense game play, and legitimate scares and horror. Bathed in gore and ultra violence the game has left a cultural legacy of concern over the impact that games have on their players, but for all the political posturing around the game here might be no better demonstration of the western relationship between the player and the gun.
