System update

[[image:System update|right|thumb|The countdown timer shown in-game when an update is imminent.] A system update is when Jagex Limited launches one or more of its updates to the main game engine. Updates are typically content-related; e.g. a new quest, a tweak/improvement to a recently released quest, or a rework of an existing section of game code.

Players are given a warning in the lower left hand corner of the game window in the form of a 3 minute countdown. When this reaches zero, all players logged in are automatically logged out and the login server for that particular world is offline until the update is uploaded. Players will have to reload the game window in order to log back in once the update takes effect.
