According to one of the players' guesses, the Fish in a Barrel mission at the beta stage of the game was a full-fledged one, and not just a cutscene. From these guesses I tried to make this mission based on DYOM 8.1. Presumably, CJ was supposed to pick up Ran Fa Li from the airport, but something goes wrong and they are followed by the Shindako family, who intend to kill both Ran Fa Li and CJ himself.
