While the China server is just preparing for the beta phase, the Chinese media got an exclusive interview with the Korean developer of Rusty Hearts. According to the article, the China server will be the first to receive a male gunner character. Update: Thanks to a tip, the male gunner is apparently named as Ian Jablonsky.
No doubt, it will be the male counterpart for Natasha, currently available in the North America server (edit: not yet, just images on website). The developers also said that a new Assassin class is being developed, while the major bosses of Rusty Hearts’ main storyline have yet to appear.
