Deathmatch, also known as free-for-all, is a gameplay mode integrated into many shooter games, including first-person shooter (FPS), and real-time strategy (RTS) video games, where the goal is to kill (or "frag") the other players' characters as many times as possible. The deathmatch may end on a frag limit or a time limit, and the winner is the player that accumulated the greatest number of frags. The deathmatch is an evolution of competitive multiplayer modes found in game genres such as fighting games and racing games moving into other genres. In a typical first-person shooter (FPS) deathmatch session, players connect individual computers together via a computer network in a peer-to-peer model or a client–server model, either locally or over the Internet. Each individual computer generates the first person view that the computer character sees in the virtual world, hence the player sees through the eyes of the computer character. Players are able to control their characters and interact with the virtual world by using various controller systems. When using a PC, a typical example of a games control system would be the use of a mouse and keyboard combined. For example, the movement of the mouse could provide control of the players viewpoint from the character and the mouse buttons may be used for weapon trigger control. Certain keys on the keyboard would control movement around the virtual scenery and also often add possible additional functions. Games consoles however, use hand held 'control pads' which normally have a number of buttons and joysticks (or 'thumbsticks') which provide the same functions as the mouse and keyboard. Players often have the option to communicate with each other during the game by using microphones and speakers, headsets or by 'instant chat' messages if using a PC. Every computer or console in the game renders the virtual world and characters in realtime sufficiently fast enough that the number of frames per second makes the visual simulation seem like standard full motion video or better.
