Larian Studios today announce the races, variations, and classes of Baldur's Gate 3's Early Access. Players will be able to select from 16 races/subraces, as well as 6 classes from day one of Early Access, October 6th.
On launch, players will be able to create humans, githyanki, elves, drow, half-elf, dwarves, halflings, and tieflings, including subraces of each race. Early Access of Baldur's Gate 3 provides around 25 hours of content, designed for multiple playthroughs. On October 6th, players will be able to create their own characters and play in either single-player, or as a party of up to four players in multiplayer, each with their own character.
Races more alien to the Sword coast - like the Drow and Githyanki - are so rare to the average NPC that you'll find their interactions to be unique as well. The world of BG3 is a highly reactive one, so this single choice will have huge ramifications across your play experience.
Baldur's Gate 3's character creation features photorealistic fantasy races, based on 3D scans of actors and models (blemishes and all), selected because their features roughly resembled the direction for each race in the game, as well of course for diversity and variety in the human-like races. Our team spent much of pre-production carefully selecting, scanning, and moulding these scans, to become the base heads for character creation. Launched into Early Access is a total of 150 heads to pick from, across the 16 races & subraces.
