Too much drink, Dr Jones?
In Lego Indiana JonesEdit
Kao Kan is a playable character in Lego Indiana Jones: The Original Adventures. Kao Kan has a machine gun, like the other Chinese gangsters. He is the last gangster you throw the diamond at for the antidote. Be careful, as he will fire his machine gun at you after Indiana Jones drinks the antidote. After drinking the antidote, Indy cuts one of the gongs down to avoid the machine gun fire.
He can be bought as a playable character in Free Play mode for 25,000 studs after Shanghai Showdown is completed.
