the party before the mission can begin. There are three pairs of missions where either one or the other must be completed before the plot progresses. Two of these pairs are selected depending on which hero was added to the party early on, while the third mission split offers a choice to the player. All the missions can be completed at the appropriate place in the plot, either depending on other players or by waiting until the plot has been completed (at which point players may gain all the heroes that they had previously chosen not to take). PvP gameplay Prior to the release of Nightfall, ArenaNet announced the PvP Editions of the campaigns they have released. This made Nightfall the first campaign where players could have access to the skills and PvP parts of the campaign without having to play or pay for the PvE parts of the game.
