However, it is possible to kill another player. Player killing , or PK , is the general term used to refer to the killing of one player by another. When a player is killed, what happens depends on how the mud is organized and on the experience level of the player. As a general rule, being killed is bad and will lead to the loss of accumulated points, skills and possessions. The policy on player killing varies from one mud to another.
Some muds prohibit the practice absolutely.
Other muds allow player killing, but only for a good reason or only in specific areas of the mud. A number of muds have a PK setting which you can control. If the setting is on, you can kill other players and they can kill you. Otherwise, you cannot be killed by another player. Finally, some muds are devoted to player killing.
