First person shooters
First person shooters are games that involve a player to shoot some sort of target, whether it's another player or a NPC. In most first person shooter (FPS) games, the objective is to get the most kills or at least more kills than the other team, often called a Death Match. In first person shooters, you are portrayed as the character while in third person shooters, you can see the character on the screen.
