One of the newer action online games in Korea now, Fighters Club will be coming within the year to English shores! This is made possible by the gaming portal, Kill3rCombo, which is a joint venture by Korean developer KOG and publisher Level Up! Games. The only game now on Kill3rCombo is Elsword North America (link).
Essentially a real fighting game which will involve many different actual fighting styles, Fighters Club gives off an old-school arcade beat-em-up feel. To me, the game should be pretty successful in catering for the older crowds as well as the young ones who are getting used to action games, similar to some popular console titles. No date is given yet, so stay tuned!
