Chaos;Child was released for the PS Vita, PS3 and PS4 in Japan on June 25, 2015 and is the fourth entry in the Science Adventures series after Chaos;Head, Steins;Gate and Robotics;Notes. Only Steins;Gate has been localized so far, with its follow-up Steins;Gate 0 to be released in the west in Q4 2016.
As PQube is the publisher for both Steins;Gate and Steins;Gate 0, it’s likely that the publisher will release Chaos;Child in the west as well. But for now we have to treat this as a rumor and wait for an official announcement. As usual we will keep you updated.
