MapleStory M is Nexon's Most Up-to-date attempt to deliver the MapleStory MMORPG to Android. They had attempted previously in 2015 with the release of Pocket MapleStory, but fans of the PC version were not too pleased with the changes made to the game and its god-awful controls. In October of 2016 MapleStory M premiered in Korea, but there wasn't any word about an English release. It looks like we know for sure that an English version is coming stateside as a public beta is on the Play Store right now. https://www.mmotank.com/Maplestory-2-Mesos.html
