Particular Reality is a project in early stage of development. You can follow its journey, starting from day one of “proof of concept” prototyping, by subscribing to the DevLog.
Many ideas put aside over years of XR development for non-gaming scenarios will give shape to a game where players can forget the limits of their play area and experience unspoiled immersion in an ethereal, unbounded game world populated by particles.
You can find further details and additional prototype gameplay on the project website.
