Guild Wars Wiki Available In-Game
Access to the game’s wiki site means that if a player becomes stuck on a quest or can’t find a location, they can check the web page in-game for answers, hints and tips rather than searching through something like Alakhazam’s in a web browser. Guild Wars players need only open up their help panel within the game to find personally tailored links on their current quests, skills, and recently visited locations. The help panel also links players to their own guild page, any allied guilds, and guilds that have sent the player invitations or granted them guest privileges.
The content of the Wiki is contributed to and edited by the Guild Wars player community, not ArenaNet so there is a chance for factual errors as well as interesting player insight.
