FPS

A FPS is a First Person Shooter game.

It works using a first person perspective, with what is on the screen action wise being what you would see if you were the character, meaning the environment and your weapon.

They often include the addition of a health meter of some sort, as well as something to indicate how much ammo you have left.

FPSs as a genre tend towards either having little if any plot whatsoever, or a decent enough plot to get the story moving.

Popular FPSs include: Counterstrike Half-Life Halo
