Previously, we have reported on Ougon Musou Kyoku (黄金夢想曲), a doujin versus fighting game based on the characters and settings from Umineko no Naku Koro Ni. There is another video featuring the gameplay elements.
Based on the video, it is confirmed that the game is a 2 v 2 tag play featuring combos and chains and it is looking lovely there.
The game is due for release next month at the Winter Comiket in Japan for the PC platform.
