Copter Carnage is a mission in Grand theft auto: Chinatown wars given to Huang by his uncle Wu'Kenny' Lee. Six waves of Spanish Lords will attack, two from the ally, two from the street, and two from besides the building. Ignore the copter and avoid it, it's invincable. Make sure not to hit the merchandise. After all the enemys are dead you must follow the copter back to the Spanish Lords warehouse. A fast but durable car is reccomended for this. Head over the East Borough bridge. Ignore the road block and crash through the toll gates and keep driving to avoid more Spanish Lords. Just keep trailing it till you arrive in Bohan. Eventually the copter lands at the warehouse. As long as you kept up, Mission Complete.
