Campaign

A "campaign" (or "chapter" - see notes) is what the developers of Guild Wars, ArenaNet, call a major expansion of the Guild Wars game series. Each of the first three campaigns is stand-alone and does not require any previous campaigns of Guild Wars to play, and must be purchased separately, as a full game, although they can be "linked" to a single account, allowing characters to travel between campaigns. The fourth campaign, Eye of the North, will be an expansion rather than a standalone.

Each campaign adds large amounts of new content, but also includes common core content present in all campaigns.

ArenaNet has stated that they plan to release two campaigns per year, and each campaign will have a development time of about 1 year.

During installation the player may choose whether he or she wants to keep his or her accounts for separate campaigns separate or if he wants to "link" (merge) them.
