Development

2Moons is a localized adaption of Korean MMORPG, Dekaron. The business model uses micropayments for premium objects from an item mall. "Sponsored" items and other advertising was also planned. Due to a preterminated contract between Mobiusgames and GameHi, Dekaron SEA has ceased its operation starting from May 8, 2010. However, players from Dekaron SEA are compensated with MU Character Packages depending on what level they attained on Dekaron SEA.

Gameplay

In Dekaron, players control a single character, and move around a three-dimensional world, completing quests and defeating fiends (which may either be monsters, known in Dekaron as the Pitborn, or other players) to gain experience and become more powerful. In terms of player and player interaction, there is also a PVP option, and sometimes a PK (player killing) option outside safety zones. The ultimate goal in Dekaron is for a player guild to obtain Genoa Castle through a siege war.

Classes

When creating a character, players select one of seven classes. Each class offers various benefits and drawbacks, as well as access to different weapons, abilities, and skill trees. Unlike several other MMORPGs, there exist no races; the only character differentiation is through class. Once selected, character classes are permanent.

• Azure Knight: The Azure Knight, a male class, are dependent on their choice of weapons; Knights can choose to use single-handed axes, single-handed maces, single-handed swords, great maces, great axes, great swords, and shields; or they can choose two single-hand weapons to become a 'dual' knight.
• Segnale: The Segnale, a vampire-like female class, have a range of effect spells, most of them curse based, including buffs to weaken enemies and party buffs. They function primarily as healers, yet they provide impressive combat skill when at a high level. They use Bloodwhips.
• Incar Magician: The Incar Magician, a female class, focuses on 'traditional' offensive spells , with many of them having affinities to natural elements. They use Staffs and Wands.
• Segita Hunter: Segita Hunters, a female class, are archer specialists, and are effective in both long-range combat and close-quarters combat. They use Crossbows, Bows (for long-range), and Daggers (for close-range).
• Vicious Summoner: The Vicious Summoners, a male class, have the ability to summon creatures (Either Beast or Libido type) to aid them. Summoners use Twin Blades and Staffs, and serve well in mobbing since their summons auto-aggro monsters as well, resulting in twice the amount of monsters to kill.
• Bagi Warrior: The Bagi Warrior, a male class, functions as a tank character, and specializes in the use of self-buffs, various combos, and knockbacks. They use gauntlets.
• Aloken: The Aloken are female class that focuses on melee and magic combat as well as numerous buffs, and function as combo-based characters. They use spears and a "guardarm" shield.

Stats

Stats are in Dekaron, as with most other MMORPGs, based on stats, or statistics.^{[clarification needed]} As you gain levels, you'll be able to put a total of five stat points to one of the four stats.

The four stats are: Strength, Dexterity, Health and Spirit.

• Strength affects the attack power of your character in melee.
• Dexterity affects the guard and block rate as well as ranged attacks (Segita Hunters mainly.)
• Health is a stat every class needs to level up. It affects the amount of health and defence a character has.
• Finally, Spirit increases the strength of magic attacks and increases MP (Magic- or Mana Points.)

Skills

Skills are why Dekaron is fun. Skills are basically attacks which are usually stronger than normal melee attacks. Other skills boosts your characters attack and movement speed, while other heals you.

• Azure Knights have skills that are mainly melee. They are powerful and create large combos.
• Segita Hunters have skills that usually are ranged, but there are some skills for the dagger.
• Incar Magicians have magic attacks and buffs.
• Vicious Summoners can summon other creatures. They also have spells and melee skills. They are basically hybrids, making their attacks slightly less powerful.
• Segnales are the healers of Dekaron. They can heal other players, but they also have a few powerful skills.
• Bagi Warriors are tank characters. They use buffs to make them able to withstand a ton of damage. They are most powerful in higher levels.
• Alokens have a few buffs, but mainly rely on Spear skills.

Mount system

Upon reaching Level 35, players may buy and use mount tokens, which give the player access to a mount for one day's time, 15 day's time, or 30 day's time. Mounts offer no benefits other than increasing a character's movement speed by 32%. Players may not use abilities while on a mount, and any buffs that were previously on the player are discontinued when that player mounts. Prices for mounts are described as extremely expensive, particularly given that mounts are rented for one, fifteen, or thirty day durations. In addition, the game's exportations system provides cheaper and faster transportation (though only between major areas).

Acclaim has recently introduced a system whereby mounts may be permanently purchased from the Acclaim Shop for some Acclaim Coins. Additionally, a new feature was added which allows players to obtain and trade 10 Piuma Feathers to an NPC in one area of the game in order to obtain a special mount named Aquira.

Dead Front

The Dead Front, which was released with Action 2, is a 24-player raid on a large castle, which is ruled by Oppucus and his serpent minions. Multiple Dead Fronts are held daily, though the number and times range based on player location. There are 6 levels of Dead Front: Rabble (Levels 21-45), Common (Levels 46-70), Baron (Levels 71-90), Earl (Levels 91-110), Duke (Levels 111-130), Arc (Levels 131-150), and Doom (Levels 151+). Using the pre-existing party function, players form seven-person groups (called parties) and apply for entrance into the appropriate Dead Front for their level. The Dead Front is accessed via the Chain of Fire, which is located in North Ares. In order to apply for the Dead Front, players must have a map of their Dead Front (i.e. Baron Map), which can be obtained by trading 20 vouchers to Tes, an NPC in Braiken Castle. If anyone in the party has no map or is not of the appropriate level, the party will be unable to apply for entrance. Of the parties that apply, four will be selected. The four parties will then speak with their Dead Front's NPC, who will teleport them into the Dead Front preparation area. This area will remain sealed for two minutes before the Dead Front begins. Each party will then receive a designated team color (either Blue, Yellow, Orange, or Purple). Each party begins in its own stretch of land, which cannot be accessed by the other parties, and must fight their way through three waves of Dead Front-specific Pitborn in order to access the convening stage, in which all four parties will convene and continue the Dead Front together. After defeating the first boss (Las Alhage), the players will continue fighting together until the final boss, Oppucus. After Oppucus has fallen, the parties will then enter the final stage, a Four-Way Party PvP. Once one team has won this stage, the overall Dead Front winner is proclaimed, and additional experience is distributed.

• Important Notes
• The Dead Front Winner is determined by the number of points each team earns. The total number of possible points is 23. Points are earned by capturing any of the three Supply Depots, dealing the most damage to Las Alhage, dealing the most damage to Oppucus, and winning the final PvP stage.
• The total time for Dead Front is 45 minutes.
• In order to access the fight against Oppucus, players must first decipher four slates (which are defended by the Magimata, a powerful Pitborn) and then read an ancient book which rests on a pedestal near the entrance to Oppucus's Sanctuary.
• In the stage where players encounter the first post-Alhage mob, there are two side paths, each of which leads to an armory. Players who raid these armories (which are defended by various serpent Pitborn) can find large amounts of DIL.
• Due to a glitch, a function called "mini-experience" exists; if a player dies during Dead Front, and is not revived/does not respawn, they will still receive full experience from the deaths of Las Alhage and Oppucus as well as if they are in one of the Four-Way Party PVP teams (never actually having to do any of the party PvP itself)

Communication

The game features an integrated shoutbox- in which a player's message is displayed to the public on the same map, a local-range chat box (which features recorded chat within a certain radius), and chat boxes specifically for guild members and party members. There is also the "whisper" option, and a private message system. You can also save the chat-bar by clicking the "Store" button.

Quests

As with almost any RPG, quests are available to players once they have reached a given required level. These quests differ in nature, ranging from running between NPCs to deliver either information or items to more difficult tasks of killing a specific number of monsters. Certain quests are unique to each class, and so rewards may differ between classes. Dekaron features a Quest Log that automatically keeps track of both completed and unfinished quests for easy reference. Certain Quests, (called Commission Quests), may be obtained from the Commission Center in Parca Temple, Draco Desert, Tomb of the Black Dragon or the Space of Pilgrimage, and they grant Adventure Points to players and a random reward, which may be donated to guilds for various rewards. There are several unique quests, but the amount of these will decrease as your gain more levels (there are only several quests from level 97+) which makes this a grindgame.

Support

Dekaron has a multi-layered support system, with GM's (Game Masters), VGMs (Volunteer Game Masters), and moderators. Each group is targeted at regulating different portions of the game. More explicit technical support is available on the Dekaron forums or in-game by simply asking a marked support member.

Events

Game Masters often enact various player-driven events for the community. They are usually scheduled and posted on the forums well in advance to allow players to attend.

Aside from special events, occasionally scheduled Double Experience events occur on Wednesdays, Fridays, Saturdays, or Sundays. Sometimes there are even 5x Experience events, but not nearly as often. Double Experience events used to be every weekend, but now it's on random times.

Combat

Dekaron has a fairly unique combat system that allows you to continually attack your opponent without getting attacked back thanks to a stun delay after every hit. Certain monsters that are at a higher level than you don't get stunned by basic attacks and my require the use of skills in combat. The combat is also much bloodier and gorier than other popular MMORPG's. As players level up the skills become more powerful and flashier

Player versus Player"PvP"

Players can duel one another with consent in any area. The victor of a duel earns PvP points; however, there is currently no known use for the points. A player defeated in a duel reincarnates on the spot with minimal health and mana.

Fights without consent (player killing(PK)) can only be performed in areas outside a safety zone. In such cases, players enter a battle status, during which the names of the fighting players turn purple. In this mode, players do not gain PvP points through victory. The victor of a non-consensual fight may gain PK and Inclination Points (IP), if the attacked player did not fight back. In such a case, the player enters a "niete" mode and the player's name turns red. However, if the attacked player fights back, the attacker will not gain IP or PK points. The defeated player, when killed, must respawn from a set return point. Inclination Points decrease over time or when being killed. Players with IP can be attacked and killed outside safety zones without consequences for the attacker. Furthermore, they may not use shops or the teleportation system, will be sent to jail if they have collected over 500 IP and get killed, and may be attacked by NPC guards. When in jail, time may be paid off with bribes.

Dekaron includes 'Attack' system, which can only be utilized in Player Versus Player combat. The shield activates only against an attack launched by another player, and it acts as additional protection and regenerates steadily after combat. Its strength is based on the armor rating, health, and level of the player. The shield prevents quick killing of weakened players, giving them a chance to run away from battle.

Experience

Experience points earned in battle vary depending on the level of the monster and the level of the player. The first attack on the monster determines who "owns" the monster; unless the first attacker is in a party with other players, whoever attacks first gains the experience and drop rights. Monsters which are five levels or more than the player's level have a display name in red; monsters which are very low in level when compared to the player have a display name in green; monsters that are very close to (or at) the players level have a display name in white. Experience gained from slaying monsters outside of a player's level is modified based on the level difference.

There are currently no penalties for player death with the exception of a 15 second respawn delay. Thus, a player can die without fear of losing experience and items. But he/she will respawn at the set return point.

Major Expansion Packs

Since the release of Dekaron, two major expansions have been issued: Bad Moons Rising and Expedition. The Bad Moons Rising Expansion added multiple new areas, dungeons, bosses, quests, skills, and items to the game. Most of these are for higher level players^[4]. The second expansion, Expedition, added a new feature to the game, allowing players to form a massive party, or Expedition Force, of 12 through 18 players to launch an attack on Karon's Transport Ship, an instance dungeon in which there are many new items and monsters, as well as a new boss, to find. Additionally, the new map Cherubim's Nest was added. The expansion Bad Moons Rising required only a standard start-up update; however, the Expedition expansion required an entire new client download, making the previous non-Expedition client obsolete.

Action Series

Dekaron is updated by GameHi using a series of "actions." Each action contains new updates, including things like glitch fixes, improved abilities (or completely revamped abilities), new armor/weapons, monsters, classes, etc. To date, there have been four "actions," with two scheduled for release.
