Master X Master

MXM was a MOBA with third-person shooter characteristics. Each player controlled two playable characters known as "Masters". There were 30 Masters as of January 2016. Each had unique abilities and different styles of play.

The Masters were characters from previous NCsoft-published games, as well as new characters. The player could switch between two Masters throughout the game, where the unused Master could regenerate its health. There was a cooldown associated with switching, as well as death. The player in MXM used the WASD keys and computer mouse to move and point the character, though the game provided the option for the player to move the character solely with the mouse.

NCsoft was beta testing the game in South Korea in October 2014, and was NCsoft's first internally-developed MOBA. Engadget did not know of a release or localization date at that time, but also reported a month later that NCsoft planned to release a mobile version of the game.

In mid-2015, NCsoft planned to release the game in a beta version globally in early 2016, with a later full-release of the game the same year. The game was still in beta test only in South Korea. In January 2016, NCsoft announced the launch of the game for personal computer in the second half of 2016 for Europe and North America. NCsoft did not announce a pay model.

GameZone was overall "impressed". IGN thought there was a lot of potential.

The game was compared to Heroes of the Storm, Smite, Diablo, The Incredible Adventures of Van Helsing, and Torchlight. IGN also commented on the crowd of MOBAs with which MXM would need to compete, noting that "standing out" would likely be challenging. Engadget suggested "it might be different enough from its contemporaries to pique your interest", while IGN thought the publisher's experience with world-building helped to differentiate the gameplay modes.
