If you have watched Chinese wuxia drama series or movies, you would have seen how some characters take on identities of others perfectly to go on spy missions or to assassinate targets with as little fuss as possible. Swordsman Online will be introducing this system, with players able to do the mentioned activities.
A simple example: If you are a wanted villain, you can use this system to become a street performer without gaining the attention of patrolling royal guards or your enemies; if you are a Royal Guard, you may disguise yourself as a wandering swordsman and mingle with the crowd to gather information (NPCs will not say these if you are wearing the uniform).
At night, players may don the black ninja-type costumes and mask to leap over buildings on spy missions. Wearing this in the day will just attract unwanted attention! All of these actions will affect the overall world storyline and quests, hence every player has the power to decide which way world progression will be heading to.
A couple of new screenshots can be seen in this post, and Swordsman Online still has no beta dated for China. I am guessing Perfect World is trying to avoid Blade & Soul China, and wait for the hype to die down a little before launching Swordsman Online. A logical business choice, but the wait is getting just a little too long…
