Chaos;Child is coming to the PS4 and PS Vita in the third quarter this year. As part of the Science Adventure Series that includes Steins;Gate (seems to include the same weird punctuation as well), you play a high school student who notices that the dates of recent deaths line up with murders that happened six years ago. He and his friends will investigate and solve the mystery.
The teaser trailer is only a quick character introduction with a cryptic intro sequence that will probably mean more to you after you beat the game. Either way, we like a good visual novel with a murder mystery to solve, and, the trailer makes us believe that the game may include the Japanese voice over when it releases outside Japan. We have no proof, but we did not hear anything that resembled English.
Check out the trailer, and let us know if you can decipher the beginning.
