First person shooters are games that involve a player to play from the first person perspective to interact with a 3D environment, Solving Puzzles, creating things, and most commonly, Attacking people or sometimes aliens or robots. 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 Team Deathmatch. In first person shooters, you view the world through the eyes of the character while in third person shooters you view the character from behind.
