PvE has been expanded when compared to the previous chapters; some parts of the game draw parallels to single player RPGs such as "" or "Baldur's Gate". For example, the player has to undertake a certain "Nightfall" mission alone, without the use of Heroes, henchmen, or other players. The mission requires very little combat and actually consists of a series of mini-games. Another example is a mini-mission that involves the player acting as a lawyer in a court case, where choosing the right line of argument will alter the outcome of the trial. The ability for the player to choose a course of action brings the game closer to its offline counterparts as opposed to the linear mission structure in other Action RPGs, as well as "Guild Wars Prophecies" and "Factions".
