As with almost any other online games which launches in Japan, it is critical to have popular characters from other franchises to make appearances. Core Masters, a MOBA developed in Korea by Soft Big Bang, introduced 3 characters from The King of Fighters 98 earlier today. Looks awesome!
Core Masters actually launched in Japan several months earlier, with the Korea native server entering beta just recently. There are several game modes, standing out from the big titles such as Dota 2 and League of Legends. The English server is still signed to Rock Hippo, a walking-dead publisher.
