Alliance

Alliance is a feature that will be rolled out with Guild Wars Factions, though as a feature and not a content, it will also be available to players who only own the Prophecies Campaign.

Alliances are formed between guilds. Each alliance can be comprised up to 10 guilds. Only the Leader and officers of the guilds may talk on the alliance chat channel. All members of the alliance and can visit each other's Guild Hall and participate in scrimmages. Players who own Guild Wars Factions can also participate in Alliance Battles in Cantha.

Alliances can control outposts in the game. Control is based on Alliance Rating, though it is not determined exactly what alliance rating gives control of an outpost. Possibilities include that the highest alliance rating on a particular side gets the "capital" (Cavalon, House zu Heltzer), and the next highest alliances get the next farthest away buildings from the capital.

There were some technical issues which the developers needed to work out at the last minute, so the Alliance feature was not avalable for the Guild Wars Factions premier, as originally planned. The feature was implemented on May 1, 2006.
