MU Online is a 3D medieval fantasy MMORPG, produced by Webzen, a Korean gaming company. MU Online was created in December 2001 by the Korean gaming company Webzen. Like most MMORPGs, players have to create a character among seven different classes and to set their foot on the MU Continent. In order to gain experience and thus to level up, a players needs to fight monsters (mobs). MU is populated by a large variety of monsters, from simple ones like goblins and golems, to frightening ones such as the Gorgon, Kundun or Selupan. Each monster-type is unique, has different spawn points, and drops different items. There are manymaps in this game. The beginning maps are Noria, where elves begin, Elveland, where summoners begin, and Lorencia, where all other classes begin. Successive maps hold stronger enemies and greater rewards, with level restrictions on each map to prevent weaker players from accessing the more difficult maps. At the start of the game the players can choose between five different character classes - Dark Wizard, Dark Knight, Elf, Summoner or Rage Fighter (the last two are playable only through a purchase from the in-game shop). After levels 220 and 250, players can respectively unlock a Magic Gladiator and a Dark Lord. Each class has its specific powers and items, making no class truly "better" than the other, and they are typically used to their fullest extent when grouped together. As characters level up and complete quests, they can transform themselves into stronger classes. Each progressive class change grants, gain access to new spells, skills, weapons and wings as well as an associated change in appearance. Like most RPG games, characters in MU can use many different kinds of magic and special abilities. Each character has its own set of spells and some weapons may be enchanted in order to provide the character with a specific spell. Casting a spell costs MP (mana, or magic point) and sometimes AG or stamina.
