NCsoft will shut down Master X Master just months after launch
The game, which only launched in June this year, hoped to position itself against genre giants League of Legends and Dota 2 but "wasn't enough to take on the established juggernauts".
In a statement, NCsoft thanked the MXM community for its support and laid out the what was next for the game.
"Deciding to close the game is not a decision we come to lightly, but ultimately it came down to a matter of business - we explored several options, but none of them were sustainable," said the developer.
"We truly believe that MXM is special, and offered a lot of new ideas to change up the MOBA genre, but in trying to carve out a niche for itself, we failed to connect with players."
Until the game goes offline in a few months, players will be able to unlock all in-game content for free, real money purchases on the MXM Store will be permanently disabled, and refunds will be issued on any purchases made between August 30 and November 16.
