Capcom Japan recently announced a brand new 3DS adventure game called Nazo Waku Yakata (roughly translated to Deluding Mysterious Mansion) and now they have a deliciously strange trailer which you can check out after the jump. It’s recommended that you use headphones so that you can hear the heavily touted “3D sound” feature that the game is putting an emphasis on. As to what the game is about? Well obviously with the presence of M. Bison, scantily clad females, and creepy singing little girls, this game is definitely about…

Yeah you’re on your own there. No word yet on a NA release, but one can ONLY hope.
