A clan is a group of gamers who play as a group in multiplayer online games. The clan can be official and enabled through a function in a game's mechanics, or it may be an unofficial clan by mutual agreement. Clans may have entrance requirements that a player must meet, such as a certain level of prowess or the completion of tasks as part of an application process. In massively multiplayer online role playing games (MMORPGs) clans are referred to as guilds, but the concept is the same.
