Today, Piranha Bytes announced that they are working on a sequel to their action-RPG Risen, called Risen 2: Dark Waters. According to the press release, the game is set years after the events of the first game, and "raging titans have devastated the world and pushed humanity to the brink of existence. Subsequently, monstrous creatures have risen from the watery depths of the sea and their attacks have brought all seafaring to a grinding halt. The hero, now a member of the Inquisition, is sent out to find out how to stop the chaos caused by these creatures from the deep."
The game is supposed to have a pirate theme, have a "highly interactive environment and a full day/night-cycle affecting countless aspects of the game world." No word on when it's supposed to be done, but it's planned for both PC and Xbox 360. A couple of concept pictures came with the announcement, which we've included below.
