CD Projekt is not only working on The Witcher 4: somewhere in the background, the far more mysterious Project Sirius is still taking shape. The multiplayer spin-off set in The Witcher universe has spent years surrounded by reworks, internal changes, and uncertainty, but it has now gained a new lead writer, which may suggest that the project is finally moving into a more stable phase of development.

Among CD Projekt’s current projects, one remains even harder to read than The Witcher 4 or Cyberpunk 2: Project Sirius. The game was officially announced in 2022 as a standalone side project set in The Witcher universe, but one that would move away from the traditional single-player RPG structure of the main trilogy. Instead, it was described as a project with multiplayer and cooperative elements. Development was originally handled by The Molasses Flood, the studio CD Projekt acquired in 2021 and later fully absorbed into CD Projekt RED’s US structure in 2025.

Project Sirius has not had a clean, straightforward development history. In 2023, CD Projekt had to rethink the project and recorded an impairment allowance connected to it, which immediately fueled speculation that the game was in serious trouble or could even be canceled. The company later said the concept had been revisited and development would continue under a reformulated framework, while also noting that a material part of the previous work would still be retained. In other words, Sirius was not restarted entirely from scratch, but it was clear that CD Projekt was not satisfied with the original direction and needed to reshape the game.

Project Sirius, The Witcher Spin-Off, Finds a New Writer

That is why the latest development matters: Kwan Perng has joined CD Projekt RED as the lead writer on Project Sirius. Perng is not one of the industry’s most widely known narrative names, but his background makes sense for this particular project. He has worked on Destiny 2: The Final Shape and Guild Wars 2: End of Dragons, and he has also contributed to the narrative side of Last Epoch. That means CD Projekt is bringing in someone with experience in fantasy and science fiction worlds, and, just as importantly, someone familiar with games where online structure and long-term player engagement are part of the design problem.

Perng confirmed the news on his own LinkedIn page, writing that he had joined CD Projekt RED as lead writer on Project Sirius. He said it would be some time before he could talk about the project in detail, but added that he had already been immersing himself in the dark and eclectic universe of The Witcher, calling it humbling to tell stories in that world alongside the studio’s developers. It is not a major reveal in itself, but for a game whose existence has often been tracked more through financial reports and job listings than through proper public showings, even a staffing update like this carries weight.

CD Projekt’s latest financial materials show that Project Sirius is still actively in development and has a meaningful team assigned to it. As of February 28, 2026, 71 developers were working on the project, more than in earlier reported periods. That does not mean a release is close, and it does not mean every problem created by the earlier rework has been solved, but the growing team, the absorption of The Molasses Flood into CD Projekt RED’s US structure, and the arrival of a lead writer together suggest that CD Projekt has not buried Sirius.

The real question is what shape this unusual The Witcher side project will eventually take. The original messaging pointed toward multiplayer and cooperative systems, while CD Projekt also stressed that narrative would remain important. That is a delicate balance, because The Witcher has always been strongest through storytelling, characters, and moral choices, not through simply turning monster hunting into a live-service loop. If Project Sirius finds its own voice, it could become an interesting experiment in using the Witcher universe outside the traditional RPG format. If it does not, it risks remaining what it has been so far: the foggiest and most repeatedly reworked project in CD Projekt’s portfolio.
