- Starts two weeks after the defeat of Sarevok, Charname hailed as hero, but suspected of a shared lineage with Sarevok.
- During this time, a holy crusade is rising in the north, besieging dragonspear castle for supplies. They're led by a woman named Caelar, whose origin is shrouded in mystery but could possibly also be a bhaalspawn. The Grand Dukes of Baldur's Gate ask you to end this crusade on their behalf, and you go north leading an army of mercenaries.
- 70 new areas, 25 voice actors with several returning from BG1/2, hundreds of new items, spells and abilities.
- Over 25 hours of new story and a bunch of side content. "Riddled with crannies" according to Phil Daigle.
- New class, shaman. Able to summon "an almost unlimited number of ghostly allies", but is rooted in place while summoning - a shaman NPC will be available.
- Meant to be more accessible than previous games without sacrificing tactical depth: new interface, journal pop-ups that deliver concise journal information (longer entries with more lore are still available); combat health bars (optional); inventory highlighting that suggests which characters to give items to.
- New difficulty modes: story mode (easy combat); "legacy of bhaal" difficulty, similar to heart of fury, for veteran players.
- Combines open-world exploration of BG1, iconic locations from BG2, art and combat from IWD.
