The Unofficial Patch is not really a mod, but while the default basic patch mostly only fixes bugs, the optional plus patch, that can be choosen at installation, is like a restoration project, adding a lot missing content, including new quests, levels, weapons, items, characters, dialogue, graphics, models, sounds and original music!
