Guild Wars: Factions Preview

IGN PC has put together a short preview of Guild Wars: Factions, based on what they know about the expansion pack so far. An excerpt to follow:
There's plenty of new content being added to the game with Factions that Guild Wars fans will undoubtedly want to get a hold of. Some of these are simply concepts while others are more "tangible." Players will now be able to form alliances between guilds. These allies will be able to visit each others' guild halls and can gain control of cities and towns on the new continent Cantha by taking part in new alliance missions. These new mission types pit multiple teams up against each other to control resource points. Victors earn faction points which will help determine control of towns and outposts.
