In 2Moons, players control a single character, and move around the world, completing quests and defeating fiends (which may either be monsters or other players) to gain experience and become more powerful.

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

Azure Knight: Knights focus on traditional m¨ºl¨¦e combat and offensive self-buffs. Knights may choose to focus on dual-wielding weapons, using shields, or using larger, two-handed weapons.
Segnale: Segnale, a humanoid rage, wield Whips of various forms and have a range of effect spells, including curses to weaken enemies and party buffs. They function primarily as healers yet they provide impressive combat skill when at high level.
Incar Magician: Magicians focus on 'traditional' offensive spells. They use either Staffs or Wands.
Segita Hunter: Hunters are an archer class, specializing in both long-range combat and close-quarters combat. They can use Crossbows, Bows, and Daggers
Vicious Summoner: Summoners have the ability to summon creatures to aid them. Summoners may specialize in either wielding Staffs or dual blades.
Bagi Warrior: Bagi Warriors function as Tank (mak ko la])|tank characters, and specialize in the use of buffs and various combos. They use Gauntlets.

Mount system
Upon reaching Level 30, players may buy and use mount tokens, which give the player access to a mount for one 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.
