Third chapter is the first one which gives us possibility to choose between two brothers McCall, Thomas and Ray. Each brother has different ability and playing with each of them you will get different experience. In subsection "Brothers" you will find detailed information about changes in gameplay.
The chapter starts with the first duel of revolvers. Move your character in the way to keep your opponent in the central part of the screen (in that way it'll be easier to kill him) and keep your hand close to the revolver (but do not grab it). After the bell rings move your hand and make a shot (the sight will be moving up and down, wait until it will be red).
After winning duel go straight to the saloon, the game will show you it. Do not pay any attention towards your enemies, your brother is skillful well enough to deal with them on.
Being inside that saloon you can kill few enemies through windows but this is not necessary. However, when they put that building on fire, take a stairs [secret].
Upstairs, you will find only one open room and making use with the backdoor, go outside.
During this part of gameplay you are save. Follow your brothers on the other side of the town. You will pass next to the weapon store [secret], depending on the brother you have chosen, buy different guns (in case of Ray take some dynamite).
A bit further climb the balcony and enter the building [secret] (doing that you will scare a lady inside). Do not waste time and leave that room, exit it on the other side.
Depending on the brother you will get different task. Taking the stagecoach or (playing as Thomas) or protecting Thomas against some enemies (Ray). One way or another you will ended up in that stagecoach and the great escape will begin.
During this part of the game you do not have to worry about foes, they will appear very often and it will be hard to hit them, but they will not make much harm to your character.
After a while you get to the place where the further way will be blocked. In that moment McCall brother will play different parts of the gameplay [secret] [secret] (details about them in "Brother" subsection). The result will be the same for both brothers, you will get back to the downtown.
At one point you will start to ram into fences 'till you will stuck because of a herd of cows. To hurry up them just shoot.
A bit later you will crash into a big building and stop for a moment inside. Being there be ready to kill one enemy from behind the counter. After leaving that place few Concentrate Mode will be triggered.
When you leave that town once and for all, you task will be to enter the stagecoach and continue shooting [T!]. Enemies will show from both sides and sometimes two or three in the same time (what is a perfect moment to use Concentrate Mode). Remember that crouching won't save you. Being in that position their bullets will still reach you and you can die very easily.
