The stand-alone Guild Wars: Factions is the second campaign in ArenaNet's massively multiplayer online role-playing game.

The Factions campaign, which can be played either connected with the regular Guild Wars or as its own separate game, includes new regions (with an entire new continent), professions, skills, missions, and monsters, along with expanded options for both Cooperative and Player-versus-Player (PvP) play, and enhanced features for guilds. Two hundred years ago, the Emperor of Cantha was slain by his closest bodyguard - a man by the name of Shiro Tagachi. When this bodyguard was finally brought to justice (read: killed), his death wail was so powerful and full of hatred that it petrified the forest and turned the sea to jade, forever changing the landscape of Cantha and its neighboring nations. In the current day, Shiro's spirit has returned to Cantha to cause havoc, and it is up to the players to stop him.

New content includes a number of the skills added to Guild Wars: Factions, including some of the deadly skills of the Assassin and the arcane spells of the spiritual Ritualist. Factions will also introduce a new PvP continent, Battle Isles. Battle Isles will introduce players to new PvP experiences, new and expanded arenas, new quests and a new explorable area as well.
