Note that the first two missions in the game do not have a name, although the game does recognize them as missions.
The game begins with you following Naz. Hold down the designated button to sprint and then press that button when you get close to an obstacle to vault over it. Keep following Naz, who has a green marker over his head, until you get a short scene. Once it plays, keeping running in the same direction you're going and jump over the big gap, busting through the door. Keep breaking through the doors until you encounter another scene that has you getting arrested.
The next mission starts with you in a jail cell, where you meet an old friend, Jackie Ma. After all of the cutscenes play out and you find out that Wei Shen is an undercover cop, you'll meet back up with Jackie on the streets. After some more scenes, you'll be introduced to the melee combat system of the game. Follow the on-screen button prompts as they show up to get through this section.
Once you take down the first set of guys, more will show up and you'll be shown the grappling system. Take out these guys with your new moves, and the leader of this pack will jump over the counter. Grab him, bring him to the flashing red counter, and press the button to use an environmental attack. These are a great way to quickly take down enemies, as they are usually one-shot defeats.
Once all of that is over, watch the ensuing cutscenes, which will introduce Winston to you. He is the leader of the Water Street Gang faction of the Sun On Yee and you'll now be working for him. One of his men doesn't trust you and brings you out back. This introduces the counter system to you, so whenever an enemy flashes red, he is about to attack you, so press the corresponding button to counter his attack. All you need to do is just survive until time runs out, which will bring this mission to a close.
