Most detailed walkthrough?

[D3lirious]

I have played through the game many times (which is my #1 game of all time btw) but have not played it for about 5 years now.
I want to go through it again and, with the help of a good walkthrough, not miss out on any quests/items/areas.
Can anyone recommend a really detailed walkthrough?
Ideally it should also cover stuff that is unlocked by the three patches I have downloaded (unfinished business, tweaks pack, and fix pack).

Dan Simpson's walkthrough is one of the best, found here. Gamebanshee's own walkthrough section is also great, especially since it includes maps.

Unfortunately, they don't include anything about the patches you downloaded, as those are relatively recent and most walkthroughs were completed a long time ago.
