Icewind Dale: Enhanced Edition Available!
Evil stirs beneath the Spine of the World.

In the northernmost reaches of the Forgotten Realms lies the region of icy tundra known as Icewind Dale. Journey deep into the Spine of the World mountains, a harsh and unforgiving territory settled by only the hardiest folk. Encounter fearsome beasts that have learned the cunning and ferocity needed to survive among the snow-shrouded peaks. Confront an evil that schemes beneath the carven glaciers and mountainsides to wreak destruction upon the face of Faerun. This is the world of Icewind Dale: Enhanced Edition.

Icewind Dale: Enhanced Edition features both Heart of Winter and Trials of the Luremaster expansions, and allows players to experience the epic adventure on Windows and Mac!
