Ah, you must be the outsider. I am Ching Tsun, a fellow student in the art of war. You see, I design and repair weapons. Perhaps you are interested?”— Ching Tsun
He is an Asian man and a very talented weapons engineer that likes to manufacture and repair weapons. Busy in his lab, he asks the Initiate to bring him some junk metal parts find into the Secret Vault, so he could create something new from them. He always carries a continuous fire laser and is very proud of it.
Later, when the people of the Secret Vault hiding in the Garden area start to evacuate, the Attis army find and attacked them, and he remained in the Garden to give the people time. Using his continuous fire laser, he killed some of the super mutants attackers but was killed by one of them, attacked in the back with an axe-like weapon.
Ching Tsun appears only in Fallout: Brotherhood of Steel.
