Chapter

A "chapter" is what the developer of Guild Wars, ArenaNet, calls a major expansion of the Guild Wars game series. Chapters are stand-alone and have to be purchased separately.

Each chapter will add large amounts of new content, but will also include content from the previous chapters (common core content for all chapters).

Chapters so far:
 * Chapter One: The original Guild Wars, released April 2005
 * Chapter Two: Guild Wars: Factions, to be released Q2/2006

Chapters are different from major updates in that they are not free and their content is not added to existing content but takes place in a new world map. While both types of releases add more locations, items and quests, chapters can add new professions and skills.
