Frequently Asked Questions

A KAL Online private server is an independent server of Inixsoft's Korean 3D MMORPG (2004). Projects recreate the game on different engines (classic, INT, latest) and rates — from slow low-rate to fast high-rate. The BestGames catalog lists 44 KAL Online projects with filters by rates, classes and engine.

Rates set leveling and drop speed. Low-rate servers stay close to the original long progression and classic feel — good if you value a steady grind. High-rate servers give a fast start and more time for PvP and endgame. The rate type is shown on each server's card.

KAL Online has six classes: Knight, Archer, Magician, Thief, Shaman and Sword Trickster. Sword Trickster starts at level 60, the others at level 1. Some private servers run only three base classes, others all six — this is noted in the project's description.

INT refers to the content of the international KAL Online server (operated by GameAgit). 'Old' engine servers stay close to the classic pre-INT build, INT adds later content, and 'latest' engine means the current client. The engine is shown in the filter and on the server card.

Decide on rates (low/high), engine (old/INT/latest) and class count, then check the server type (PvP, PvE, RP) and community language. Compare projects in the BestGames catalog by filters and open a server card to see the details before signing up.

KAL Online — why the classic endures

Inixsoft launched KAL Online in 2004 and re-released it on Steam in 2016. Its Korean oriental-fantasy atmosphere, large-scale castle sieges and the teacher–student system keep a community around private servers, where projects recreate the game across different engines and rates. The BestGames catalog gathers 44 KAL Online projects in one place — with filters by rates, classes and engine, so picking a server takes minutes, not an evening on forums.
