Prologue: Go Wayback! is now permanently free to own on Steam, and anyone who paid for it during early access can claim a full refund with no strings attached. The survival game from PlayerUnknown Productions, the studio founded by PUBG creator Brendan Greene, has been pulled out of early access, shipped one last update, and left available for anyone who wants to keep playing it.
Quick answer: Add Prologue: Go Wayback! to your library for free on its Steam store page. If you bought it in early access, request a refund through Steam’s standard process before Monday, August 17, 2026, and mark discontinued development as the reason. You can re-add the free version afterward.
What changed for Prologue: Go Wayback!
The game entered Steam Early Access on November 20, 2025, priced at $20 (€19.99). Less than a year later, on June 3, 2026, the studio announced it was halting development after running out of money to keep funding the project, which led to layoffs. Rather than delisting the game, PlayerUnknown Productions moved it into a full release state on June 17, 2026, and made it free.
The reason for leaving early access was deliberate. Keeping a game with no further development in early access could mislead new players into thinking work was still ongoing, so the team marked it as released to keep it playable without setting false expectations. It is not a finished game, but it works and now costs nothing to claim.
What’s in the final update
The last update adds trails to the world. These connect cabins and shelters that sit close together, and they can branch out to other clusters, sometimes leading into meadows and cliffs, with only a small chance of hitting a dead end. Settings let you increase the distance over which these connections form, though pushing that higher raises the risk of running into paths that cut off unexpectedly.
Two new items arrive alongside the trails. A handheld weather monitor shows current and incoming weather, and higher-tier versions add details such as humidity and temperature. A waterproof spray protects everything from clothing to fragile items like paper and matches. The studio also improved the cooking system, liquid handling, item descriptions, visual effects including lighting and fog, and audio consistency.
If you want to experiment, you can switch on the developer build from the “game versions and betas” menu in your Steam library. The studio says this version is close to the live game but adds a menu on the = key that lets you spawn items, change the time of day and weather, fly across the map, teleport, and more. The game files have also been left unencrypted for modders. The team had hoped to add official mod support and documentation, but ran out of time and resources to finish that work.
How to claim a refund
The refund offer is the part that stands out. Anyone who paid the $20 (€19.99) early access price can get their money back regardless of how many hours they played or how long ago they bought it. That sidesteps Steam’s usual rules, which deny refunds after 2 hours of playtime or 14 days from purchase.
Note: When you refund the game, it is removed from your Steam library. Adding the free version back restores access at no cost.
What happens to Melba and the studio
Prologue was always a test bed rather than the end goal. It existed to show off Melba, the studio’s in-house engine built to generate earth-scale procedural worlds in Unreal Engine 5. Each launch generated a fresh 64 km² map offline on your own PC. Work on Melba continues with a smaller team, and the studio’s earlier tech demo, Preface: Undiscovered World, stays on Steam in early access at no cost for anyone curious about the technology.
Greene framed the decision as a funding problem the wider industry shares. He said he was privileged to have kept the studio’s lights on himself for a while, a luxury few independent developers get, but that he could only do it for so long before moving forward with a smaller team and looking for the right partners for the project.
He thanked his team and said he was proud of what they built, adding that he truly regretted they couldn’t finish the journey they began together. Prologue: Go Wayback! remains free to keep and play, and the broader Project Artemis vision the studio is chasing still rests on the engine work that continues beyond it.
