Gekkeiju Online: The Beginning is an MMORPG/VRMMORPG-hybrid where players all around the world assume roles of heroic fantasy characters in a gigantic new world that is being re-populated after a massive cataclysm. A World full of magic, mysteries and perils awaiting for brave adventurers. Virtual Reality-mode is powered by native Oculus Rift-support.
The game is currently being ported to Unity in order to keep supporting virtual reality as well as to add better graphical effects.
The Unity Client will likely catch up with the current version during next year at which point it'll replace the other one.
