What the store does identify

The saved Steam requirements list Windows 10 or Windows 11 in a 64-bit environment. They also list DirectX 12 and an internet connection requirement. Those are compatibility requirements, not an identification of the software engine used to develop the game.

Why the collected video cannot answer this

The gameplay trailer candidate did not provide a caption track in the collection run. Its visuals were not independently reviewed here. Even a visual resemblance would not establish a specific engine or engine version without direct supporting evidence.

What remains Not confirmed

The engine family, engine version and rendering pipeline are Not confirmed. No engine claim has been inferred from system requirements, graphical style or the publisher's other projects. This page preserves the unanswered technical question instead of attaching an unsupported technology label.
