Neverwinter Nights: Diamond

A plague known as the Wailing Death is terrorizing the city of Neverwinter. Lady Aribeth summons an adventurer, who teams up with her fiance Fenthick Moss and his friend Desther to capture four monsters which are needed to prepare the cure. However, the matters become more complicated when the protagonist is attacked by mysterious assassins. It seems that an evil cult is behind the infestation, and the hero must find out what its ultimate goals are, and eventually save the city.

Neverwinter Nights is a role-playing game based on the third edition of the Advanced Dungeons & Dragons rules. The game utilizes 3D graphics with a zooming function and free camera rotation. Combat is handled in real time, and is similar to that of Baldur's Gate series, allowing the player to pause in-battle to issue orders. Unlike other RPGs that utilized this system, Neverwinter Nights allows the player to fully control only one character. Various "henchmen" may join the hero during the journey, but their functionality as party members is limited, as they cannot level up, have no inventory, and only follow general commands.

The multiplayer modes include Dungeon Master, in which a "DM" controls the traps and battles set for other players in the dungeon, and a range of game types such as hunting for treasure or a simple death match battle between players. The game also comes with an extensive tool kit for the construction of custom adventures. It allows players to create their own maps using a tile system. It is possible to add objects to the areas and even produce scripted events, cutscenes, and conversations.

The Diamond Edition includes the original Neverwinter Nights and three official expansion packs: Shadows of Undrentide, Hordes of the Underdark and Kingmaker.
