CD Projekt Red have just announced the much anticipated Witcher 4 is in development, but perhaps most interestingly to game developers, they have also announced they are switching from their long running in-house game engine REDEngine to Unreal Engine 5. Beyond being a simple user, Epic Games and CD Projekt will work together an improving open world support in UE5.
Details from the announcement:
This is an exciting moment as we’re moving from REDengine to Unreal Engine 5, beginning a multi-year strategic partnership with Epic Games. It covers not only licensing, but technical development of Unreal Engine 5, as well as potential future versions of Unreal Engine, where relevant. We’ll closely collaborate with Epic Games’ developers with the primary goal being to help tailor the engine for open-world experiences.
At this point, no further details regarding the game — such as a development time frame or release date — are available.
REDengine, the technology which powers Cyberpunk 2077, is still being used for the development of the upcoming Cyberpunk 2077 expansion.
