Digimon Masters

, also known as Digimon Masters Online, is a Massively Multiplayer Online Role Playing Game by Digitalic for the PC. It was originally going to be released in English by WeMade in December 2010 but was delayed until early 2011. It was then announced in July 2011 that JoyMax would be hosting the game. In February 20, 2012 Aeria Games launched its own server, Seraphimon. When moving the English version over to, MOVEGAMES took over the publishing rights.

In 2022 the game will be overhauled, with the engine changing to.

Game Basics
The game is based on the anime series Digimon Data Squad, with supporting NPCs drawn from other anime series as well. The player begins by choosing between Marcus Damon, Keenan Crier, Yoshino Fujieda, and Thomas H. Norstein as the appearance of the character and then choosing one of four partner Digimon. The player then completes quests and levels both the character and the Digimon, as well as collecting new Digimon. New Digimon are acquired through a "mercenary system" involving either the hatching of partner eggs or the usage of a serial code found on select Korean Digimon cards.

Characters
There are four selectable Tamers and four starter Digimon. Marcus, Thomas, Yoshino, and their Digimon were included in the game's release, while Keenan and Falcomon were released in later updates for both the Korean and English versions.

Unused Digimon
Ebemon and Labramon have unused models in the game's code.

Hatching Mercenary Digimon
Hatching is the process by which a player obtains mercenary digimon. It involves retrieving the normal eggs that are dropped by defeated opponents, cashing them in at an NPC to get data chips, and using these data chips to hatch mercenary digimons from special partner eggs.

There are currently nine types of data chips:
 * Beast
 * Rock
 * Devil/Dark
 * Bird
 * Dragon/Reptile
 * Plant
 * Fire
 * Insect/Bug
 * Aquatic

Battle
Battling is done in real-time. At all times the currently selected partner Digimon follows the player. The player initiates combat by clicking on the selected enemy or walking near a boss enemy. The player's Digimon then approaches the enemy and immediately performs their standard attack. The player's Digimon has a health bar measuring health and a DigiSoul meter. The DigiSoul meter measures how much energy the Digimon has to use special attacks. When empty, the Digimon can only use standard attacks. While in combat tamers are able to use items that restore health and DigiSoul but must wait several seconds before being able to again. After the enemy Digimon is defeated the player and Digimon receive varying amounts of experience points depending upon the level of them and the enemy.

There is a tool bar running along the bottom of the player's screen with two columns. The first has a small thumbnail of the Digimon and click-able icons for the Digimon's special attacks. As the player levels up they have access to more attacks. The second column has a small thumbnail of the player and click-able icons for telling the Digimon to: attack, run away, stop attacking but not run away, and pick up dropped items.

Combat takes place in real time with nearby players able to watch and even join in on battles; however, the only person who will receive experience and any dropped items is the player who attacked first. Players can also join temporary "parties" where players share all experience points gained in battle.
