To look around before you commit, try it now as a guest; the guest option gets you into the game without sign-up.
What to check before you choose a server
The question most players ask about a server is how the game works and what it asks of you. To tell the server types apart and spot the security basics, the private server checklist covers four points: price, whether anything is installed on your PC, whether you reuse your password and whether you plan to share your account. On ChromeKO registration and play are free, and the game runs in your browser.
A server's own settings matter too. ChromeKO follows the official USKO settings, and the way progress takes effort is explained in the USKO server guide. The current rates are shown live on the home page, so this guide gives no numbers that could go stale.
A new server: starting from zero
ChromeKO opened in October 2026, so progress is just beginning for everyone. The new Knight Online server guide explains how players starting from zero can found or join a clan and take part in the first events, castles and kings. For a plain summary of how and where to play today, read the Knight Online 2026 guide.
When you are ready to start, the sign-up guide walks you through opening an account and creating your first character. Because the server is new, patience and taking the first steps in order pay off.
Server types: PvP and private servers
In Knight Online, PvP means players fight monsters and each other. ChromeKO is a Knight Online PvP server, with the Karus and El Morad nations, nation wars, castles and kings as part of the game. Players search for this as web PvP or mobile PvP; the web and mobile PvP guide summarizes both. The PvP server guide explains what to look for in a server of this kind.
"Private server" is a different question: can I trust the place I am playing? The checklist above answers it. On ChromeKO you play in the browser, install nothing on your computer, and register a free account if you want to play under your own name.
Coming back or chasing the old feeling
If you played years ago, the first step back is still opening the game in your browser. The return guide gives a seven-day plan with a phone shortcut, quests, a party and a clan. If you want the old atmosphere, the nostalgia guide explains how to start in Moradon and move on to other zones.
First choices: nation and clan
On a new server, your first big choice is your nation. Karus or El Morad decides who you play beside, which castle and king you support and which side you fight for in nation wars. Before you pick, look at which nation your friends are in; the nation choice guide lists the points to compare.
A clan is the easiest way to play together. Clans show their identity with capes, compete in the clan ranking and fight together in Border Defense War and castle sieges. The clan guide explains how to find, join or found one. For the event list, see the events guide and the events page for the calendar.
Progress on an effort-based server
Effort means progress takes time and commitment rather than shortcuts. On an effort-based server, steady play beats a single long session: keep up with your quests, hunt in a zone that matches your level and make the most of the weekend EXP bonus. The quest guide explains how the quest system works, the leveling spots guide shows where to hunt, and the EXP bonus guide covers the weekend boost. Playing with friends also helps; the party guide explains shared EXP and the drop bonus.
