🔥 KO4FUN – 5 Years Strong! The Original Academy System & Ultimate Knight Online PvP Experience 🔥

Hey Knights, GM Patos here.

Since 2020, we’ve been running KO4FUN non-stop for 5 years, continuously improving and delivering the best Knight Online experience. Many servers make bold claims, but we’re the ones who actually innovate. The Academy system that redefined seasonal KO? It started here, and others have only tried to copy it.

🏛 Three Servers, One Connected World
Immortal – Our final and permanent server, running for over four years with zero wipes. This is where legends are made and live on.

Genesis – The yearly seasonal server where players grow, fight, and prepare for the final merge into Immortal.

Academy – Our own creation, opening every month for 10 days of intense competition. After each cycle, Academy merges into Genesis, fueling constant battles and rivalries. After the tenth Academy, Genesis unites with Immortal, carrying forward everything players have achieved.

⚔️ Why KO4FUN Leads the Way
Custom-built game engine delivering features and performance no other private server can match.

Fresh content with official updates plus our own unique additions.

Fair, skill-based PvP – no pay-to-win mechanics.

Regular tournaments with real cash prizes, making every fight matter.

Robust infrastructure with servers in Europe and Asia for low latency, and US servers coming soon for the best ping worldwide.

Active community & dev team that listens and evolves the game with the players.

It’s no surprise other servers try to copy our ideas – the difference is, we set the standard.

🚀 Get Ready for the New Season
The new Genesis season begins Friday, August 1st at 9 PM server time.
This is the perfect time to return or start fresh. Build your character in Academy, climb the ranks in Genesis, and claim your legacy in Immortal.


Gather your friends, form your clan, and prepare for a season full of battles, rewards, and history in the making.

See you on the battlefield,
KO4Fun team.
