It seems that Obsidian Entertainment is working not only on Avowed and The Outer Worlds 2, but also on some unannounced game. A mention of the project was found on the LinkedIn page of the studio's creative director, Daniel Cabuco.
There are no details yet, but it is surely a big game. Cabuco has extensive experience in the industry and has worked on The Legacy of Kain: Soul Reaver, Lost Planet 3, and Death Stranding.
The development of the new project may be led by game designer Josh Sawyer, known for Fallout: New Vegas. His latest work was the role-playing adventure Pentiment, where players, in the role of a medieval artist, must track down a murderer.
Many fans hope that this mysterious project will turn out to be a new Fallout. Meanwhile, Josh Sawyer once mentioned that he would be happy to release the third part of Pillars of Eternity.
Let's recall that the next game from Obsidian, the fantasy role-playing game Avowed, will be released this year. You can watch detailed gameplay here.
