There's no question that Neverwinter Nights: Hordes of the Underdark is currently one of the best-looking RPG's on the market. Although the game still pretty much clings to the basics of the NWN engine, there are plenty of neat new effects to behold during gameplay. New spells and a huge number of impressive-looking new character and creature models all contribute to a gratifying visual experience. There's also a wide range of new tilesets exhibited throughout the game and a notable variety of details in the backdrop. Other features such as lighting, shadows, and character animation, all stay true to the original and Shadows of Undrentide. To cut a long story short, the game boasts an overall visual quality that will probably put it in the very top of contemporary PC titles.​
