Editing Deathmatch (video games) (section)

== Gameplay ==

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. Players often have the option to communicate with each other during the game by using microphones and speakers.

Deathmatches have different rules and goals depending on the game, but an example of a typical FPS-deathmatch session is where every player is versus every other player. The game begins with each player being "spawned" (starting) at random locations—picked from a fixed predefined set. Being spawned entails having the score, health, armor and equipment reset to default values which usually is 0 score, full (100%) health, no armour and a basic [[firearm]] and a melee weapon. After a session has commenced, arbitrary players may join and leave the game on an ad hoc basis.

=== Players ===
In this context a ''player'' is a human operated character in the game or a character operated by a computer software [[AI]]—a ''[[Video game bot|bot]]''. Both the human and computer operated character do have the same basic visual appearance but will in most modern games be able to select a ''skin'' which is an arbitrary graphics model but that operates on the same set of movements as the base model. A human player's character and computer bot's character features the same set of physical properties, initial health, initial armour, weapon capabilities, the same available character maneuvers and speed—i.e. they are equally matched except for the actual controlling part. For a novice player the difference (i.e. experience, not taking into account the actual skill) between a human opponent and a computer controlled opponent may be near nil, however for a skilled player the lack of human intelligence is usually easily noticed in most bot implementations; regardless of the actual skill of the bot—which lack of intelligence can be at least somewhat compensated for in terms of e.g. extreme (superhuman) accuracy and aim. However, some systems deliberately inform the player when inspecting the score list which player(s) are bots and which are human (e.g. OpenArena). In the event that the player is aware of the nature of the opponent it will affect the cognitive process of the player regardless of the player's skill.<ref name="ARS_GAME_BRAIN">{{cite journal|last=Timmer |first=John |url=https://arstechnica.com/science/news/2009/02/humans-think-different-when-told-theyre-playing-a-human.ars |title=In games, brains work differently when playing vs. a human |journal=BMC Neuroscience |doi=10.1186/1471-2202-10-9 |publisher=Arstechnica.com |date=2009-02-05 |volume=10 |pages=9 |pmid=19193204 |pmc=2667181 |access-date=2011-05-31 |doi-access=free }}</ref>

Modern implementations allow for new players to join after the game has started, the maximum number of players that can join is arbitrary for each game, map and rules and can be selected by the server. Some maps are suitable for small numbers of players, some are suitable for larger numbers.

===Deaths===
The goal for each player is killing the other players by any means possible which counts as a frag, either by direct assault or manipulating the map, the latter counts as a frag in some games, some not; in either case—to attain the highest score—this process should be repeated as many times as possible, with each iteration performed as quickly as possible. The session may have a time limit, a frag limit, or no limit at all. If there is a limit then the player with the most frags will eventually win when the session ends.

The health variable will determine if a player is wounded; however, a wounded player does not entail reduced mobility or functionality in most games, and in most games a player will not bleed to death. A player will die when the health value reaches equal to or less than 0, if the value is reduced to a very low negative value, the result may be [[Gib (video gaming)|gibbing]] depending upon the game.

In most games, when a player dies (i.e. is fragged), the player will lose all equipment gained and the screen will continue to display the visible (still animated) scene that the player normally sees, and the score list is usually displayed—the frags. The display does not go black when the player dies. Usually the player can choose to instantly [[respawn]] or remain dead.

The armor variable affects the health variable by reducing the damage taken, the reduction in health is ''in concept'' inversely proportional to the value of the armor times the actual damage caused; with the obvious differences in various implementations. Some games may account for the location of the body injured when the damage is deduced, while many—especially older implementations—do not. In most games, no amount of armor causes any reduced mobility—i.e. is never experienced as a weight issue by the player.

The lost equipment (usually not including the armor) of a dead player can usually be picked up by any player (even the fragged player, respawned) who gets to it first.

===Simulation===
Newtonian physics are often only somewhat accurately simulated, common in many games is the ability of the player to modify the player's own vector to some degree while airborne, e.g. by retarding a forward airborne flight by moving backwards, or even jumping around a corner. Other notable concepts derived from the physics of FPS game engines are i.a. at least [[Bunny hopping|bunny-hopping]], [[strafe-jumping]] and [[rocket-jumping]]—in all of which the player exploits the particular characteristics of the physics engine in question to obtain a high speed and/or height, or other attribute(s); e.g. with rocket-jumping the player will jump and fire at rocket at the floor area immediately under the feet of the same player, which will cause the player to jump higher compared to a regular jump as a result of the rocket blast (at the obvious expense of the health variable being somewhat reduced from self-inflicted injury). The types of techniques available and how the techniques may be performed by the player differs from the physics implementation as is as such also game dependent.

Most modern deathmatch games features a high level of [[graphic violence]]; a normal modern implementation will contain high quality human characters being killed, e.g. moderate amounts of blood, screams of pain and death, exploding bodies with associated ''[[gib (video gaming)|gib]]s'' are common. Some games feature a way to disable and/or reduce the level of gore. However, the setting of the game is usually that of a fictional world, the player may resurrect in the form of mentioned ''respawning'' and the characters will usually have superhuman abilities, e.g. able to tolerate numerous [[point blank]] hits from a machine gun directly to the head without any armour, jumping extreme inhuman distances and falling extreme distances to mention a few things. These factors together may make the player experience the game less real as the game contains highly unreal and unrealistic elements.

===Powerups===
All normal maps will contain various [[power-ups]]; i.e. extra health, armor, ammunition and other (more powerful than default) weapons. Once collected by a player the power-up will respawn after a defined time at the same location, the time for an item to respawn depends upon the game mode and the type of the item. In some deathmatch modes power-ups will not respawn at all.

Certain power-ups are especially powerful, which can often lead to the game rotating around ''controlling power-ups''—i.e. all other things being equal, the player who controls the strongest power-ups (collecting the items most often) is the one that will have the best potential for making the best score.

===Sessions===
If the session does have a frag or time limit a new session will start briefly after the current session has been concluded, during the respite the players will be allowed to observe the score list, chat and will usually see an animated [[pseudo]] overview display of the map as background for the score list. Some games have a system to allow each player to announce they are now ready to begin the new session, some do not. The new sessions might be on a different map—based on a map list kept on the server—or it might always be on the same map if there is no such rotating map list.

Common in many games is some form of message broadcast and private message system; the broadcast message system announces public events, e.g. if a player died it will often be informed who died and how, if fragged, then often by what weapon; the same system will also often announce if a player joins or leaves the game, and may announce how many frags are left in total and other important messages, including errors or warnings from the game; instant text messages from other players are also displayed with this system. The private message system, in contrast, only prints messages for individual players, e.g. if player A picks up a weapon, player A will get a message to confirm that the weapon was picked up.
