Guild Wars: Updates @ Official Site

Head on over to the official Guild Wars for the latest edition of The Scribe and a new State of the Game article that takes a closer look at Alliance Battles.

What is an Alliance Battle, anyway?

One of the new competitive map types in Guild Wars Factions is the Alliance Battle. In the game, there is an ever-present front line that moves between the two warring factions of the Luxons and the Kurzicks. Depending on how well each side is faring the border can shift left or right and affect the control of some outposts. The border dictates which map an Alliance Battle is taking place on. If the border has been pushed all the way to the Luxon side then the map will have a heavy Luxon advantage. Likewise, if the border has moved to the Kurzick side, they will gain an advantage to compensate for lost territory. The main Alliance Battle map is Saltspray Beach, which is playable when the border is dead center.
