First thought to be the mobile version of Concerto Gate, it was revealed recently that Perfect World China is actually working on Cross Gate’s mobile version, the working title of the original game. A teaser trailer was recently shown, and it retains the classic turn-based combat of the classic game.
There is currently no confirmed schedule, and do note that Cross Gate is officially licensed from Square Enix. It is a trend for the bigger companies, such as Tencent Games and Perfect World, to actually pay royalty for IPs these days. The Ninja class looks really cool!
