A new PvP arena was available specifically for players to fight each other with their Heroes but has since been removed. Heroes are unlocked through play and can be taken into PvE areas. The player also has a degree of control over the actions of the heroes: the player can set map waypoints for them, controlling the type of AI they use and directing the skills they use. Heroes are customizable in that the player can select skills, armor upgrades and weapons for them. New henchmen available through Nightfall and Guild Wars: Eye of the North are called Heroes. In previous campaigns players could use NPC Henchmen with predetermined sets of skills to assist them with their questing. If a person owns both campaigns, Assassin and Ritualists can travel to participate in Guild Wars Nightfall but they cannot be created in Guild Wars Nightfall. The Assassin and Ritualist can only be created through the Guild Wars Factions campaign. Heavily armored, they are a support character capable of helping teammates through the use of "shouts" and chants, which affect all nearby allies.
Nightfall is a new stand alone campaign - there is no need to buy the 2 previous campaigns to play.Twenty new missions and hundreds of quests are included, in what is more than just an expansion pack even if it’s not quite a new game. Guild Wars: Nightfall is set on the new continent of Elona and features two new classes of character to play as: the long range Paragon and the magical Dervish. Dubbed the world’s first co-operative online role-playing game (or competitive, depending on your temperament), Guild Wars manages to distinguish itself from the crowd by moving the focus away from constantly levelling up and focusing it squarely on combat between and against players.
