MapleStory Classic World (often called OSMS, for Old School MapleStory) is an upcoming classic edition of MapleStory, recreating the pre-Big Bang era of the game within the existing Global MapleStory (GMS) client. Unlike a temporary or seasonal event, it is intended as a permanent server with ongoing support. Nexon announced the project in April 2025 during the 20th anniversary celebration of Global MapleStory, with original Wizet designer Nemi serving as lead designer.
Nexon set the dates in its Ossyria Exploration Report of 21 August 2026: Founder's Package sales from 2 September 2026, Founder's Access from 6 October, and Grand Launch on 21 October 2026. The same report holds Orbis, El Nath and the 3rd job advancement back from the launch build, to be reworked and introduced gradually afterwards.
The project targets the "old-school" era of MapleStory, which during the 2000s was among the most popular MMORPGs alongside titles such as World of Warcraft and RuneScape.
The game world is Windia, which is divided into channels.
Contents
The world at launch
Grand Launch opens one continent. A character starts on Maple Island, which covers levels 1 to 10, then crosses to Victoria Island and spends the rest of the run there. Ossyria is not part of the build.
-
Maple Island: the first ten levels, ending at the boat in Southperry. -
Victoria Island: six towns and everything from level 10 onward.
| What | At launch | Documented on this wiki |
|---|---|---|
| Monsters | 73 | 73 |
| Maps | 303 | 303 |
| Quests | 293 | 293 |
| NPCs | 195 | 195 |
| Skills | 80 | 80 |
| Items | 2618 | 2673 |
| Shops | 30 | 30 |
| Music tracks | 67 | 75 |
The right-hand column is larger because the wiki also documents what was played in the second Closed Online Test and held back. Those pages carry a banner and are collected in Category:Not at launch.
Towns
Maple Island has two towns: Amherst, where a character first opens their eyes, and Southperry, where the boat leaves. Victoria Island has six, four of which hold a job instructor. Florina Beach is reached by ferry from Henesys and has no monsters on the town map itself.
-
Lith Harbor: the port where every arrival from Maple Island steps ashore. -
-
-
-
Kerning City: the Thief home town, in permanent night. -
Sleepywood: no instructor, and the way into the dungeons under the continent.
Only Perion and Henesys have portals to the Free Market, the shared trading hub. The Henesys portal is in Henesys Market. See Maps for the full list, and the route planner for how to get between any two of them.
Characters
Every character begins as a Beginner and takes two advancements: a branch at level 10, then a specialisation at level 30.
| Branch | Second jobs | Primary stat | |
|---|---|---|---|
 |
Warrior | Fighter · Page · Spearman | STR |
 |
Magician | Wizard (Fire/Poison) · Wizard (Ice/Lightning) · Cleric | INT |
 |
Bowman | Hunter · Crossbowman | DEX |
 |
Thief | Assassin · Bandit | LUK |
The third advancement exists at level 70 and is not in the launch build. Nexon has said its skills will be reworked before they are introduced, so the ones documented here are what was playable in testing rather than what will ship.
Appearance is chosen at character creation and can be changed later with coupons, covered at character appearance. What the four ability scores do is set out at Stats, and how a character spends its skill points is where the branches diverge in practice.
Monsters
73 monsters are in the launch build. They run from a level 1 Snail in the hunting grounds of Maple Island to the level 80 Jr. Balrog at the bottom of the dungeon network under Victoria Island.
| Levels | Some of what you fight |
|---|---|
| 1 to 10 |  Snail ·  Blue Snail ·  Shroom ·  Red Snail ·  Stump ·  Slime ·  Pig ·  Orange Mushroom ·  Ribbon Pig
|
| 11 to 20 |  Dark Stump ·  Octopus ·  Green Mushroom ·  Bubbling ·  Axe Stump ·  Stirge
|
| 23 to 35 |  Dark Axe Stump ·  Wild Boar ·  Iron Hog ·  Jr. Wraith
|
| 38 to 50 |  Lorang ·  Zombie Lupin ·  Copper Drake ·  Wraith ·  Drake
|
| 52 to 75 |  Croco ·  Stone Golem ·  Red Drake ·  Wild Kargo ·  Tauromacis ·  Taurospear
|
Six bosses are in the build, on their own respawn timers:
Mano (20) · 
King Slime (32) · 
Mushmom (40) · 
Zombie Mushmom (50) · 
Jr. Balrog (80)

What else is in
- Crafting: six professions, with their own recipes and materials.
- Party quests: instanced, party-based objectives.
- Citizenship: town residency, with a Community Board of rotating daily errands and weekly donations.
- Fame: the reputation number other players raise or lower, and a gate on some equipment.
- Guilds and parties: the two grouping systems.
- Gamepad support, which the original game never had, alongside a choice of three starting key layouts, three saved presets, and a twelve-slot quick bar.
Items divide into equipment, use items, etc items and setup items, bought from shops or dropped by monsters. Mesos are the currency; see Money making guide for what actually pays.

History
MapleStory launched in South Korea on 29 April 2003, developed by Wizet. Regional versions followed: Japan on 3 December 2003 and China on 23 July 2004. The Global (North American) version, GMS, launched on 11 May 2005, with a dedicated European service opening on 12 April 2007.
In 2010, the Big Bang update overhauled the game's core mechanics, leveling curve, and world layout. The change proved divisive, and a significant portion of the veteran player base left in the period that followed. The desire to preserve the pre-Big Bang experience drove a long-running private server scene, with patches such as v62 and v83 becoming common reference points for the era MapleStory Classic World aims to recreate.
Development and testing
Following the April 2025 announcement, Nexon ran a private playtest in June 2025, reportedly selecting around 30 participants from over 18,000 applicants. A public hands-on demo took place at MapleCon LA in October 2025, followed by additional in-person testing at Cyber City in Gardena, California, from 15 January to 13 February 2026. A worldwide closed beta test, the first opportunity to play remotely, ran in early 2026.
A second Closed Online Test followed in August 2026. It included Orbis, El Nath and the third job advancement, none of which are in the launch build. Much of what this wiki records about that content comes from it.
