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 campaign is stand-alone and does not require any previous campaigns of Guildwars to play. Each campaign must be purchased separately, as a full game.

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

ANet plans 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 wants to keep his accounts for separate campaigns separate or if he wants to "link" (merge) them.

Campaigns so far:

• Campaign Zero: Core content shared by all campaigns.
• Campaign One: The original Guild Wars, a.k.a. Guild Wars Prophecies, released April 28, 2005
• Campaign Two: Guild Wars Factions, released April 28th, 2006
• Campaign Three: Guild Wars Nightfall, released October 27th, 2006.
• Campaign Four: title unknown, in development

Notes

• "Chapter" is not the official, preferred term any more. This is probably because ArenaNet wants to avoid the impression that the campaigns are in any sequential order.
• See Skills by Campaign for a listing of which skills are available in each campaign.
