Psysonic Omega is based on a fictional background and story after RA3: Uprising. We will present three new factions that are developed from original factions in RA3. They are la Commune, Commonwealth Of Sovereignty and a nameless faction using advanced Imperial Arsenal from Shiro Sanitarium. This mod is not just for better graphics performance or more enjoyable gameplay experience, but for a further story after RA3's present plot. In this mod, plenty of new units and structures that basically expand the Style of original RA3 are added. New story and interersing ideas will be implemented.
