• First known MU Online version with a numerical number.

0.32 aka 0.32.0 (20.07.2001)

• Adjustments to Agility based Defense and Defense rate for the upcoming Fairy Elf (FE) release. Consequently, major balancing issues can be avoided since Fairy Elf (FE) is Agility based.

• Introduction of 3^rd character: Fairy Elf (FE) in addition to Dark Knight (DK) and Dark Wizard (DW).

• Introduction of Fairy Elf (FE) items: Vine set, Silk set, Wind set, Spirit set, Short Bow, Crossbow, Bow, Golden Crossbow, Elven Bow, Arquebus, Battle Bow, Light Crossbow, Tiger Bow, Serpent Crossbow.

  • Some sources claim that the sixth set mentioned by MU Korea (muonline.co.kr) is Guardian set. The issue with that is the fact that Guardian set was added on drop list on version 0.45. See below. The sixth bow is claimed to be Silver Bow. However, that one was added on drop list on version 0.45 as well.

• Added map Noria.

• Added Healing Orb, Orb of Greater Damage and Orb of Greater Defense.

0.35 aka 0.35.0 (10.08.2001)

• Introduction of Guilds.

• Added background music.

  • Interestingly, MU Online intro song and many map theme songs were written/composed by Jeong Jae-hwan (Bound Media) and performed/recorded by the Seoul Metropolitan Chorus.
  • Music integration initially relied on a supporting executable called MuPlayer.exe. Later, likely in some version between 0.99B+ and Season 1, the use of MuPlayer.exe was replaced by the wzAudio.dll library.

• Maximum item level increased to +9.

• Introduction of Item Options.

• Added Switch Character option at 'Esc'.

• Introduction of in-game currency Zen.

19.11.2001

• 'Commercial launch' (Grand Opening) of MU Online in South Korea.
  • Webzen does not specify what version was considered as the commercial launch of MU Online. However, knowing the timeline and patches announced, we can safely assume that the version 0.45 or 0.46 is the version when MU Online was launched officially. Everything until then was Open BETA.

0.47 aka 0.47.0 (11.12.2001)

• Introduction of 4^th character: Magic Gladiator (MG).

• Introduction of /item name and # functions.

0.48 aka 0.48.0 (18.12.2001)

• Added map Atlans. Entry level requirement of 100.

• Added Crystal Sword, Crystal Morning Star, Aquagold Crossbow, Bluewing Crossbow (Legend Crossbow), Staff of Resurrection.

• Added Scroll of Aqua Beam.

• Added Unicorn (Storm Crow) Gloves, Unicorn (Storm Crow) Boots. Unicorn (Storm Crow) Pants and Unicorn (Storm Crow) Armor were not a part of the initial release. A likely explanation is that Unicorn (Storm Crow) Armor has Item level 80, Unicorn (Storm Crow) Pants have Item level 74. The strongest monster in Atlans is Hydra with Monster level 74.

  • However, on test server and test patch Hydra was level 72. Therefore, it could not drop Unicorn (Storm Crow) pants with an Item level 74. Likely Hydra's drop table was not adjusted initially even though it was released as a level 74 monster on the main server.

• Maximum level limit increased from 255 to 298.

  • Discrepancy exists since live evidence does not support the claim. The publicly available 0.75 KOR protocol client, while running on OpenMU server, still has the maximum level of 255.

• Bug fixes.

  • Interestingly, Battle Soccer was introduced to commemorate the 2002 FIFA World Cup, which took place in South Korea and Japan.
  • Interestingly, Webzen had planned to release 'Dark Wolf', a unique pet for the Dark Knight (DK). However, it was never implemented. Traces of it still exist in decompiled code from early game versions. Some speculate it was later reworked into Fenrir, the pet released for the Dark Lord (DL).

• Added macro function /1 /….

• Added /request on and /request off.

0.66c aka 0.66.3 (15.07.2002)

• Bug fixes.

0.66d aka 0.66.4 (18.07.2002)

• Bug fixes.

0.68 aka 0.68.0 (08.08.2002)

• Introduction of Jewel of Chaos.

  • Likely introduced in version 0.67 on the main server. Test server 0.67 and 0.68 patches do not mention Jewel of Chaos at all. Main server 0.68 patch explains that Jewel of Chaos can be obtained as a drop from monsters. Main server 0.68 patch is a fix to a previous patch that introduced Chaos Machine (likely 0.67 just like on the test server).

• Introduction of Chaos Machine.

  • Likely introduced in version 0.67 on the main server just like on the test server. The 0.68 patch mentions a fix to a previous patch introducing Chaos Machine. We do not have version 0.67 main server news update, just from the test server.

• Added Chaos Lightning Staff, Chaos Nature Bow, Chaos Dragon Axe.

  • Likely introduced in version 0.67 on the main server just like on the test server. The 0.68 patch mentions a fix to a previous patch introducing Chaos Machine. We do not have version 0.67 main server news update, just from the test server.

• Introduction of 1^st Level Wings (Satan Wings, Angel Wings, Fairy Wings).

  • Likely introduced in version 0.67 on the main server just like on the test server. The 0.68 patch mentions a fix to a previous patch introducing Chaos Machine. We do not have version 0.67 main server news update, just from the test server.
