Boston-based developer The Molasses Flood has merged with CD Projekt Red as part of the CDPR Group.

In a statement posted on its website, it said the merger occurred on April 1, 2025.

It had previously been announced in CD Projekt’s FY24 financial results “to ensure better alignment in scope and direction” of Project Sirius – a multiplayer set in The Witcher universe announced in 2022.

Molasses Flood has “ceased operations” as a “separate legal entity” as a result of the merger, with CD Projekt Red assuming “the rights and obligations” of the studio.

The developer clarified the merger will not affect the availability or distribution of its games The Flame in the Flood and Drake’s Hollow, and that both will continue to be published by CD Projekt Red.

Molasses Flood co-founder Damian Isla said that the decision was “a good and healthy thing for the studio” in post on LinkedIn.

“It breaks down some organisational barriers, and better integrates The Molasses Flood team with the rest of the amazing CDPR organisation,” Isla wrote.

“Overall, it shows a very bright future for Project Sirius. It’s going to be an amazing game, and I cannot wait until the rest of the world learns about what we’ve been working on.”

Isla also announced that he would be parting ways with the studio.

“Molasses Flood has been a huge part of my life for the past decade plus, and I’m proud of having been a part of building something that lasted as long as The Molasses Flood did in a market environment often quite hostile to tiny teams like ours.

“I think we made some beautiful, memorable, and quirky things, and I’d also gotten to work with some of the kindest, most generous and talented people in the industry.”

Molasses Flood was acquired by CD Projekt Red in 2021 for an undisclosed sum. Once acquired, it began working on Project Sirius which was announced in October 2022.

Development of this project was written off in March 2023, which cost more than $7 million in 2022 and $2.2 million in 2023.

This decision was attributed to a reset in development “based on results of evaluation of the scope and commercial potential of the original concept […] and ongoing work on formulating a new framework for the company.”

As a result of this, 29 employees were laid off in May 2023 which made up roughly half its development team.

Project Sirius hasn’t been abandoned, and is currently still in development. In its latest financial results, CD Projekt Red confirmed that the game had entered pre-production.
