Rumor Claims Obsidian Has Been Developing a New Fallout Game for Two Years Using Unreal Engine

A new report suggests that Obsidian Entertainment has been quietly working on an unannounced Fallout project for the past two years. The rumor follows recent confirmation that Bethesda and Obsidian are collaborating on a new entry in the series, with multiple sources claiming the project was originally greenlit after Microsoft reorganized Xbox Game Studios and shifted development priorities. While the game has not yet been officially revealed, insiders believe development has been underway for significantly longer than previously thought.

According to the latest claims, the new Fallout title is being built with Unreal Engine 5 rather than Bethesda's traditional Creation Engine. If accurate, this would mark a major technological shift for the franchise, potentially delivering improved visuals, faster development, and more advanced world-building tools. However, several reports note that Bethesda has not confirmed which engine the project uses, meaning the Unreal Engine detail remains unverified.

The rumored game is believed to be a standalone Fallout adventure rather than Fallout 5, which Bethesda recently confirmed is currently in pre-production while The Elder Scrolls VI remains the studio's primary focus. Reports indicate that Obsidian's project is intended to expand the Fallout universe alongside future remasters and Bethesda's mainline sequel, allowing multiple Fallout experiences to be developed simultaneously.

Neither Bethesda nor Obsidian has officially announced the new game or shared details about its setting, gameplay, or release window. Until an official reveal takes place, information regarding the project's development timeline and its use of Unreal Engine should be treated as speculation. Even so, the possibility of a new Fallout RPG from the creators of Fallout: New Vegas has generated enormous excitement among fans eager to return to the wasteland.
