PlayerUnknown Productions, the studio founded by PUBG creator Brendan Greene, has announced layoffs amidst a company restructuring.

Alongside news of the layoffs is the confirmation that development on Prologue: Go Wayback has come to an end.

The survival game launched into Early Access on Steam in late 2025 and served as the first major showcase for the studio’s proprietary Melba terrain-generation technology.

Designed as an open-world survival roguelike, it generated unique wilderness environments for every playthrough, challenging players to survive dynamic weather conditions and unpredictable landscapes.

In a statement addressing the decision on, Greene explained that the studio’s ambitions had grown beyond what could realistically be supported through personal funding:

When PlayerUnknown Productions became an independent studio in 2021, we embarked on a journey to achieve an ambitious vision for the future.

Our goal has been to develop technology that can break the boundaries of scale, which currently limit how large virtual worlds can be. To achieve this, we built a research team to develop our Melba technology and a team to develop our first practical application of our terrain generation technology: Prologue: Go Wayback.

Unfortunately I have reached the limits of how far I can continue to fund this journey in its current form. As a result, I have made the hard decision to restructure the studio. We will continue developing our Melba technology with a smaller team, while halting further development of Go Wayback. Our immediate priority is to support our affected employees to the best of our abilities during this difficult transition.

We plan to make Go Wayback available for free for all future players with an upcoming update. We are also investigating offering players who have purchased the game on Steam and Epic Games Store a way to receive a refund. We will have more details on this in the near future.

Lastly, I want to thank our community and everyone who has been involved in supporting our studio’s journey so far.

While this marks a disappointing end for Prologue in its current form, for now, the priority is supporting affected employees and continuing research into the technology that originally inspired the game.
