Neverwinter nights 2 : Mask of the betrayer is it like a campaign... I mean it has plot right?

MoTb is the expansion for nwn2, like shadows of undertide and hordes of the underdark where for nwn1. It is its own campaign (3 acts) you may use a character that has finished nwn2 if said character is under level 18 MoTb will level you up to there to start (this will also happen if you start a new character). It has also removed the level 20 cap and extended it to level 30 (the 4 class restriction remains). There are 3 new races (Genasi,Half-drow ,Wild elf )as well as 7 new classes 2 base classes (Favored Soul,Spirit Shaman) and 5 prestige classes (Arcane Scholar of Candlekeep, Invisible Blade,Red Wizard of Thay,Sacred Fist, and the Stormlord). There are also 2 new camera angles.





So in other words, yes is your answer.
