Kenneth Suk-Wah, one of the bosses, is encountered at the end of The Hong Kong Massacre's second chapter. This page contains tips for defeating Kenneth Suk-Wah.
This is a mandatory boss fight that takes place after you complete all missions of the third chapter - Two Days Earlier.
Just like with the previous bosses, the rifle is the best weapon to defeat Kenneth. Getting all upgrades, especially 10 Clip Size and Extra Clip, for this weapon is also highly recommended. Thanks to that you can complete the entire level without picking up weapons dropped by defeated enemies.
The fight with Kenneth is very similar to the previous boss fights (those that took place at the end of the first and the second chapter). The location where you face the boss is vertical. This time, you need to jump from one rooftop to another.
If you have a rifle with a lot of ammo, you can defeat Kenneth in the starting location. Hide behind the crates (presented in picture 1) and jump out to shoot 2-3 times (picture 2). Aim at the boss before you leave your cover - your bullets will have an increased chance of hitting the target.
If you run out of ammo, go north. Watch out, you will encounter single enemies. Don't let them surprise you. Pick up their weapons.
You don't get any trophies/achievements for defeating Kenneth Suk-Wah. However, the game will reward you with one 1 star. You also unlock the fourth chapter (Yesterday).
