Player Killing

The removal of players from active gameplay through active actions.

Many games let players or the system take aggressive actions or cause negative effects on other players, and this can result in the affected players not being able to play temporarily or permanently. This is called Player Killing because the actions leading to it is often diegetically represent as killing their avatars or characters.

Examples

Chess can be seen as an archetypical Player Killing game - the winning condition is to check mate the other player which in principle is the same as showing that one can kill the king. Although not necessary to win, players of Diplomacy and Risk greatly increase their chances of doing so by eliminating other players. In contrast, Monopoly does not have Player Killing even if player can be eliminated from the game. This since the elimination is caused indirectly by other players actions and they have no way of distinguishing between which other players may be effected by their actions.

Category:Tabletop Roleplaying Games such as Dungeons & Dragons and GURPS have Player Killing as soon as it is possible for players to die in them since game masters can be seen as responsible for the deaths in nearly all cases. The exception is when players kill each other which of course is another instance of Player Killing. In Live Action Roleplaying Games all killings tend to be Player Killings since all being that can be killed in these games are played by humans (the rare exception are mechatronic monsters such as the dragon in Dragonbane).

Deathmatch games in First-Person Shooters, found for example in Counter-Strike, Quake III, and the Unreal Tournament series, have Player Killing as the main goal. The more other players the player manages to take out, the more points or "frags" he is rewarded. The players who are killed usually lose their gained special items and abilities and are transferred back to a spawn point. Frag is an example of a Board Game built around the same core gameplay. In the Online Game Defense of the Ancients players can be killed with negative consequences for their team but the deaths are temporary. Although not as common in Massively Multiplayer Online Games, some early examples such as Ultima Online and Genocide allow or even focus exclusively on Player Killing.

Using the pattern

That players can have their avatars or characters killed is always an explicit design choice, as is incorporating other design aspects that can effectively hinder them from participating in gameplay. This does however not always translate into Player Killing since those noticing players subject to these events must also perceive that somebody is actively trying to make this happen. This make it central to the pattern that some form of Agent can be linked to actions causing the events. This said, making Player Killing possible in games consist of deciding what actions and events can cause it, who can cause it, and what the effects of the killing is.

Combat is probably the most obvious action that can lead to Player Killing, but any way of directly causing Ability Losses or Damage can be used. If the use of Traps causes Player Killing is less clear - it depends on if those observing the trap being sprung perceive it as actively having placed there by Agents and that they can at least suspect who did this. Related to the question of what actions can kill is the question of what can be killed. Avatars and Characters are apparent choices here, used for example in the Unreal Tournament series and Dungeons & Dragons, but losing all Units in Risk shows that Player Killing does not need to be localized to specific Focus Loci. Diplomacy goes one step further, players are not eliminate due to lack of army Units but lack of supply centers.

Making it possible for other players to perform the actions that can lead to "player" deaths (i.e. having Player Killing in a Multiplayer Game) is a guaranteed way to ensure that players can identify the actions as ones coming from Agents. Enemies controlled by Dedicated Game Facilitators may or may not work depending on how much players perceive the individual Enemies as being Agents in their own right; for the same reason AI Players can work but is less likely to work than human players. Game Masters are more likely than other types of Dedicated Game Facilitators to support Player Killing since players can fall back on seeing the Game Master as the source of the killing if the Enemies are not seen as being Agents.

Player Killing can lead directly to Player Elimination if Permadeath is used in a game, and will do this sooner or later if Lives are used.

Ability Losses

The most common effects of Player Killing

Downtime In practice, suffering a Player Killing is always a Penalty

Designing Player Killing in the game obviously involves deciding the details of Spawning and Penalties involved for being killed. Usually they are mainly Individual Penalties even in games with Team Play, and players receive Decreased Abilities, Ability Losses, and they might lose Ownership of Tools and other items they possess at the time of killing. Other possibilities include forced Downtime or limitations to the number of times a player can respawn due to the use of Lives.

Player Killing can be used as a method of keeping Score in both games with Team Play, as in games with Team Elimination, and without Team Play. Games with Team Play sometimes allow the players to Eliminate their team members, and this can be called unintentional Player Killing. On the other hand, some team-oriented games break Consistent Reality Logic by not having the possibility of Player Killing within the same team in order to avoid internal fighting and possibilities for saboteurs.

Consequences

Since Player Killing removes players from gameplay it gives them Downtime but can also lead to Player Elimination if combine with Permadeath or the loss of one's last Life. The possibility of Player Killing naturally gives rise to Tension to players, although how intensely this is experienced depends on the actual Penalties involved in dying and the Rewards given for killing. The Tension is usually not as drastic if the Player Killing does not lead to Player Elimination.

In Multiplayer Games, the possibility of Player Killing leads to reciprocal Risk/Reward situations for the players since they are potential or real threats to each other.
