It's largely going to depend on how you play it. If you do the side quests, you'll add around 2-3 hours to it.

Description
"Random attacks by hordes of orcs and giants. Travelers killed by marauding undead, rumblings from the Underdark, and a city thrown into chaos. Everything seems to be directed from some higher power, but why? A call has been made for heroes, for you, to put a stop to this evil, but that just might be exactly what this evil power wants you to try to do...can you survive The Challenge of the Overfiend?"
This module is designed for 1 character of 20th level or better with 1 - 2 henchmen.
You will need SoU and HoTU both installed to play this as well as patch 1.68.
I don't use any HakPaks in this, just code that I modified from the original campaign and the expansions packs and scripts that I have composed myself. I have cutscenes that I put in it and quite a few AI scripts to make enemies a little smarter. There are henchmen in the game you can get to join you, as well as 2 additional characters that will join you at the end if
certain conditions are met. There are also a few suprises here and there.
I have made a multitude of updates to this that you can find in the readme file.
*Note* I'm finding that it is a good idea to save the game immediately after you begin the module and then reload. The game should then work pretty smoothly afterwards. I'm not sure why this is, but the scripts seem to fire properly after an initial reload.
I did a lot of tweaking to this. Deleted a lot of dialogue, changed dialogue, scaled down enemies, and added some spell-casting command options to 2 of the henchmen.
