Compare this chapter to the previous, you might feel that this one is completely different and original. The whole way you will be forced to go dawn the scaffolding. Reaching the bottom you will mount your horse and run from that place. A breathtaking view, especially at the first stage of the chapter, will varied you way through the waves of opponents.
The chapter will start when all brothers McCall are kept in the shed on the top of the mountain. Fortunately, William will manage to free his hand and to untie the rest of the crew. When you will start moving around take the nearby chair and wait next to the door for an enemy. At the very moment of opening the door, hit him with your chair and grab his gun (in that way you will get your weapons as well) and shoot the rest.
Further way until the end of the chapter will lead you down the mountain and that's way do not waste your time and follow your brother. Take the first stairs and another [secret].
In that way you will reach the place where a lift to the bottom of the scaffolding will be started and the first opponents (except of those who attacked you after leaving the shed) will strike. Their number won't be large so you shouldn't have any problems with eliminating them.
A bit further, after covering another footbridge, you will reach the first Cooperative Concentrate Mode, next to the entrance to a cave. Active that action and kill guys inside.
Another few will hide a bit further on your left.
The whole way to the exit you will be forced to shot but the number of the enemies won't be overwhelming so you should cover that cave very smoothly.
After leaving that cave once again follow your brother and go down the scaffolding. You will reach a place with a drawbridge [secret] and the first special tasks for both brothers (details in "Brothers" subsection).
When the bridge will be lowered go through it and continue you way down the mountain. At one moment some enemies will attack you. They will lie in wait on a distant footbridge (right screen). There won't be a lot of them so the fight won't be hard.
After a few steps you will reach another cave  [secret] with Cooperative Concentrate Mode. Activate it and kill enemies inside . This time their number will be a bit larger but still you will be able to kill all of them during the slow-mo.
