MapleStory 2 was a 2015 massively multiplayer online role-playing game (MMORPG) developed by NSquare in association with Nexon and NCSoft. MapleStory 2 was released free-to-play first in Korea. The game takes many of the features of the original game, MapleStory, and applies them to a 3D voxel-based environment. Most enemies, NPCs, and locations made a return in this sequel, although with several changes.
