Yakuza 4

You’ll be playing as Taiga Saejima in Part 2.

Chapter 1 - No Substories
Part of this chapter involves a Prison Break section where your objective is to break down doors while avoiding fire from the Sniper on a Tower. Hide behind crates and obstacles when you see the laser target turn red to avoid taking damage.

Boss Battle: Guard Saito and his goons are trying to stop you from escaping. Make use of Saejima's Charge attacks to make short work of them, pickup the keycard from Saito to open the door and escape.

Chapter 2 - No Substories
This is a very short chapter, and you're thrust into a fight with Kazuma Kiryu. He's practically undefeatable unless you utilize your Charge Attacks, which makes the fight immensely easy.

Chapter 3 -11 New Substories
Unlike Akiyama, you need to steer clear of Policemen while playing as Saejima. The final section of this chapter involves a tournament with 3 cage fights with Ivan Ibrahimovic as the final challenger. Use the same moves as before and you'll win easily.

Chapter 4 - 3 New Substories
You won't have lots of room to move in this chapter as Police Lookouts are everywhere and you're limited to using Rooftops and Underground Sewers to move around. Upon entering Millennium Tower, you'll be confronted by waves of Yakuza, and finally Minami again. He's no different from the fight with Akiyama, so just beware of his Flame Breath attack and you'll be fine.

Boss battle: Majima Goro, utilizes knife attacks and is very quick at evading. What you should do is wait for him to perform his lunge or leap attacks, sidestep them, drop in a combo and repeat. There will be a couple of QTEs during the fight: If you succeed, you get a huge boost to your HEAT gauge, if you fail you'll be on the receiving end of some serious damage.
