Icewind Dale II is a computer role-playing game developed by Black Isle Studios, released in 2002. The game is set in the Forgotten Realms Icewind Dale region, and is the sequel to Icewind Dale and its two expansions.

Like its predecessor, Icewind Dale 2 takes place long before the events described in R.A. Salvatore's Icewind Dale Trilogy made the area a well-known part of Faerûn. The plot itself is often influenced by or refers to events that happened in the original Icewind Dale.

Like the previous games in the series, Icewind Dale II is based on the BioWare Infinity Engine. The game incorporates nearly all of the changes and additions to the series made by the Heart of Winter and Trials of the Luremaster expansion packs.

Icewind Dale II was the final Infinity Engine game, and the last Black Isle Studios game released for PC. After their next game, Baldur's Gate: Dark Alliance II, they were shut down by Interplay Entertainment, their parent company.

Unlike its predecessors, the game is based on the Dungeons & Dragons 3rd edition ruleset, which brings such things to the series as feats, the ability for any race to be any class, and the ability for any class to use any weapon. As in Baldur's Gate II: Shadows of Amn, the 3rd edition character classes of Barbarian, Sorcerer, and Monk are present in the game, but unlike that game there are also many sub-races, such as Drow, and Tieflings, which all have racial advantages and disadvantages.

The basic gameplay of Icewind Dale II is quite similar to that of its predecessors, as well as the other games developed on the Infinity engine. The combat system is a quasi-real-time adaptation of the normally turn-based Dungeons & Dragons combat system used - dice rolling and the like are all done automatically, without requiring the player's participation, although it is possible to pause the game at any time to issue orders to the party.

Character generation is very different from the earlier Icewind Dale games, however. Instead of the usual virtual dice-rolling process to determine the amount of strength, dexterity, constitution, intelligence, wisdom, and charisma a character will have, the player is given a set amount of points to distribute amongst a character's various statistics. Also included are the D&D 3rd edition components of Feats and character abilities. Among other things, these replace the simple "weapon proficiencies" of previous Icewind Dale games. This, combined with inclusion of more classes and sub-classes, as well as more races and sub-races (all with their own advantages and disadvantages), makes Icewind Dale II's character generation much different from its predecessors.

Another significant change is the once more increased bestiary, which now includes such creatures as bugbears, hook horrors, and driders, as well as many returning monsters from the previous Icewind Dale game and its expansion packs, the Baldur's Gate series, and Planescape: Torment. In addition, a much larger section of Icewind Dale is explorable than in the previous games, with the game's six chapters (each broken up into around 3 thematic sections of around 2-3 maps each) providing a large amount of play value.
