The summer 2002 release of Bioware's Neverwinter Nights gave many hardcore PC gamers a much-needed RPG epic amidst the annual summer drought. With 3D environments, tons of spells, weapons and a good narrative to boot, this action-based adventure even rivalled games such as Warcraft 3. It is a fine game in its own right, but with the addition of the Shadows of Undrentide expansion pack, it stands even taller as one of the best RPGs the PC has to offer.A hideous evil has awoken in the Forgotten Realms, and in order to save the inhabitants of Neverwinter, you must uncover a sinister conspiracy, unmask your mysterious betrayer and complete an epic struggle to defeat the powerful forces that conspire to unleash an evil your people would never survive. This is the story that accommodates this massive RPG, offering a 60-hour single player game and multi-player options. And that's without the addition of Shadows of Undrentide.In Shadows of Undrentide, players can begin their adventures in the small mountain town of Hilltop as a student under the tutelage of a mage named Drogan, before traversing the deadly Anauroch Desert in search of the ancient ruins of Netheril. Players must again uncover a fiendish plot whilst battling a multitude of new enemies through over 20 hours of original, new gameplay. Players can choose from any of the classes in the original, or try out one of five new Prestige Classes. Players can also customise their characters even more with a choice of 50 new spells and 30 new feats.Shadows of Undrentide is clearly a worthwhile expansion pack that, given its depth, could be a stand-alone game in its own right.
