Epic Games has unveiled an initial roadmap for Unreal Engine 6: Head of Development Marcus Wassmer outlines a timeframe for the Early Access launch and explains how UE5 and UEFN will converge.
Last month, Epic Games announced the new Unreal Engine 6 somewhat unexpectedly, but revealed very few details.
Two Key Dates for Early Access and Full Release
According to Wassmer, the plan for the next two years is clearly laid out:
- The Early Access launch is scheduled for late 2027, and according to Epic Games, the final version is set to follow twelve to eighteen months later—meaning early 2029 at the earliest.
- Until then, according to the blog post, UE5 will remain the production foundation for studios that are already releasing games today.
At its core, this merges two previously separate development lines: Unreal Engine 5 and the Unreal Editor for Fortnite (UEFN)—the tool that allows developers to build their own content directly within Fortnite.

In addition, Epic Games is launching a new UE6 development branch at GitHub.
As with its predecessor, this branch is publicly viewable, allowing interested parties to follow along in real time as the team works. However, Wassmer also explicitly states that this is not an alpha version, but is intended solely to promote transparency.
Why the Merger Is Taking Two Years
Epic Games attributes the long timeframe to the fact that developers are simultaneously building a new programming model called “Verse” and a new gameplay framework called “Scene Graph.” Both are intended to make it significantly easier for developers to launch new games.
In addition, there will be open standards for content that can be shared across games, as well as deeper integration of AI tools such as Claude and Codex via the MCP protocol.
No Abrupt Switch for Existing UE5 Projects
According to Wassmer, anyone currently working with UE5 or UEFN won’t have to start from scratch. Epic Games says that existing systems like Actors and Blueprints will be retained in early versions of UE6 and will only be removed once the new framework is mature enough—at which point conversion tools will be provided to facilitate the transition.
According to Epic Games, there are currently no plans for a separate UE5 version following the also-announced update to version 5.8, but the team is keeping a version 5.9 open as an option.
