Mission 10: Chain of Evidence - Sleeping Dogs: Definitive Edition (Xbox One)

Wei is contacted by Tiffany, who's currently in possession of a 9mm pistol belonging to Charlie Pang (whom she used to date). He has no problem agreeing to take the pistol off her hands, which makes her happy. Later, Wei calls Raymond and tells him he has Charlie Pang's pistol. He tells Wei to come down to the underpass. When there, Pendrew appears instead and makes Wei reenact the shootout from before to frame Charlie Pang for the murder of an unnamed Triad member. This mission serves as a tutorial on how to shoot guns.
