Reigniting the old flame.

UPDATE: All owners of the game can go ahead and grab the Rum Runner's Pack for free. It adds six new alcohol-themed items and Mirke, a recruitable sidekick that really loves her booze.
If you don't own the Deluxe or Obsidian edition of the game, you can also now purchase the game's Sountrack separately.

Note: If you already own the first Pillars of Eternity on GOG, go to your library and look under Serial Keys. You should see a bonus code which you can use to redeem your Gaun's Pledge DLC for Pillars of Eternity II.

Pillars of Eternity II: Deadfire is here, DRM-free on GOG.com.
The sequel to Obsidian's seminal RPG, which brought back all the immersion and attention to detail we remember from the genre's classics, has finally arrived. Introducing naval battle mechanics, a new vast open world, a relationship system that now affects interactions between your companions, and an epic story involving the re-emergence of an old god, it might just become the RPG you'll be replaying for all eternity!

Go for the Deluxe Edition, which includes a Digital P&P Guide, the official OST, the second Volume of the Digital Guidebook and more. You can also grab that stuff separately inside the Explorer's Pack.
Or plan for the future with the Obsidian Edition, which also grants you access to the Season Pass, that contains the first three pieces of planned DLC.
