This is a guide for the The King of Chinatown mission in Hitman: Absolution. It describes the score maximizing way to complete this mission, which includes getting a signature and silent kill on The King of Chinatown, how to hide his body and how to recover the evidence and stay undetected. All of this on the purist difficulty.
Locate the King of Chinatown
At the start make your way to the middle of the square until the objective completed message for finding The King of Chinatown pops up.
Eliminate the King of Chinatown with Silent and Signature Kill
Find a spot that gives you a clear view of the middle of the square:
And wait for the drug dealer, who wears a white jumper and a golden chain around his neck, to get there. He then waits for the King of Chinatown to return and talks to him. After that he goes to get the drugs. Follow him and once he is in a side area subdue him:
Take his outfit and hide the body in one of the dumpsters. Go back up to the middle of the square and pick up the evidence that is on the table with the coffee on it. Then find the King of Chinatown. He will be near the exit on the opposite side of the Chinatown Square than you entered. Walk into his sight. After a bit of talking he will follow you. Take him up to the apartment that overlooks the square. The entrance to it is down a side alley off the main square area on the right side of the Chinatown Square compared to where you entered it:
Go all the way up and into the apartment. Select the fiber wire. It will be easiest to take him out when he is bent over doing drugs, but any time you see the garrote prompt is a good time to take him out:
This will cause a silent and signature kill on The King of Chinatown. Be sure to hide the body in the cabinet that is also in the apartment to gain some extra score. You can now leave the Chinatown Square via the exit you found The King of Chinatown next to earlier:
