Perfect World and Cryptic Studios, the companies that never sleep, released the Underdark expansion for Neverwinter today. It follows the tale of Drizz’t Do’Urden by author R.A. Salvatore and his attempt to vanquish the Demogorgon, a horrible 2 headed beast in a 10 person encounter. A storyline given by Drizz’t himself, we’ll see our adventurer on another campaign quest along the sword coast.

“With the all-new 10-player encounter against Demogorgon, Xbox One players have yet another large scale experience to play in with their friends. On top of diverse new experiences for players, Neverwinter is now closer to Dungeons & Dragons than ever before,” said Rob Overmeyer, executive producer of Neverwinter. “Creating adventures featuring iconic D&D heroes like Drizzt and Bruenor is an awesome opportunity, and Underdark wouldn’t be what it is without the integration of R.A. Salvatore’s story-telling and characters. Looking at 2016, we’re excited to continue strengthening our ties to D&D as well as delivering MMO experiences players want.”
