The server became public not so long ago. Therefore bugs are expected. Our team is fully commited to provide you the best experience we can so please bear with us while we are fixing the upcoming bugs.

If you want to experience Conquer Online at its best with all the classic features there were and with lots of new custom content that will surely spice things up then Black Side CO is the right place for you.



All classes, items, and spells are fully implemented, tested and work exactly the same as official Conquer.


In order to make it even more enjoyable for you to play our server, several PVE Quests have been included. They all had a few tweaks in order to spice them up a bit. On Black Side CO you can find quests such as DisCity, AncientDevil, SnakeKing, BlueMouse, among others.


In order to spice up things a bit, we have added several PVP Events as well. We're striving for new ideas so that we can make more PVP Events and add them to our current list. There are hourly PVP Events such as FB/SS Skill Based and Last Man Standing, Class Based Wars, Top Spouse Tournament, Weekly Tournament and so on.


The server is developed and maintained by a group of talented individuals with extensive experience in development, management and game play.

Custom Quests/Events

This is probably the type of feature that we will want to invest most of our time in. It is also for sure the one we are expecting you to help us with. On Black Side CO we aim for an unique experience for our players, therefore we are always striving to add new events that you can find nowhere else. Feel free to contact us with any ideas you have and we guarantee we will discuss them.
