XENO DRAGON is an MMO strategy RPG where you grow while enjoying adventures with cool dragons. You can acquire dragons and equipment of various attributes through various events, challenges, and markets. Go on an adventure to the continent of Holivia with your XENO DRAGON! Dungeon mode is a game mode in which you can acquire Gears of Dragon. Depending on the game's story, players will be given the opportunity to visit the heads of each of the scattered Dragons in the Olivia continent, to be tested by them, and to obtain a random Gear as a reward. The heads of Dragons guarding Dungeons in each region have their own powerful attributes, so challenging Dragons have to pay attention not only to their abilities, but also to the coherence of attributes. Dungeons are divided into four categories. In addition, the Gear sets that each Dungeon can get as a reward are all differentiated. As a result, the player repeatedly challenges Dungeon to get the Gear he wants. Each Dungeon has four difficulties: Easy/Normal/Hard/Very Hard, and the probability of obtaining a rare Gear is also different depending on the difficulty. Expedition mode is a game mode that explores unknown parts of the Olivia continent and collects unused Element crystals that were collected by ancient Dragons. This Element crystal is an item that Dragon can use to grow through adventures and reach the limit level, and you get different Element crystals from region to region. It is divided into four categories: 1 hour / 3 hours / 6 hours / 12 hours, and the amount of compensation for the Element crystal is differentiated. Arena mode is a game mode that allows players to test each other's strength through competition
