Neverwinter Nights: Hordes of the Underdark is the second expansion for the revolutionary role-playing game Neverwinter Nights. BioWare has created a dark and dangerous world of adventure set in the world of Dungeons & Dragons. Your hands are callused from many years of weapon play, your mind is sharp from hundreds of books studied, your feet are nimble from slipping unseen and unheard past thousands of guards and your faith is unshakable in the gods you worship... but will it be enough for this final terror?
