Expansion pack

From Talus Wiki

Neverwinter Nights (NWN) has two expansion packs: Shadows of Undrentide (SoU) and Hordes of the Underdark (HotU).

It is recommended to first play the NWN Original Campaign with a new character. The SoU campaign should be played with another new character, since the storyline runs in parallel with the NWN story. Finally, the HotU campaign can be played with the SoU character, since the story assumes you've gone through SoU (NPCs will make references to past exploits).
