Basically, you'll have control of Max for the next 10 minutes or so but you won't do anything more than walk. Eventually, you'll be coming up on a bar and Max will say something about the irony of it. At this point, look left to find Anders the ex-cop in an open window. Make your way up the hill and at the top, enter the bar. After a little while, you'll get a gun from Da Silva. Not long after that, the shooting starts.
You'll be attacked by a group of three men at first. After you kick the table at them, go kill the three of them quickly. Just behind them down the stairs to the right will be a fourth enemy and shortly after that, the bartender will take out a shotgun and shoot at you. Kill him quickly and you should be much safer. At this point, go down the stairs and watch for the couple of guys up by the pool table. After you kill them, go right and take cover behind the bar by the pool table as three more enemies come out of the hall near the pool table. From this angle, they should be easy pickings. Kill all three.
Head back to the table that you were originally sitting at and you should find a picture of Serrano nearby. Head towards the back of the strip club and in the bathroom by the pool table will be part of the Golden Sawn Off. Grab that and fight your way through the back hallways. As you take your first right, one enemy will come around the corner. Behind him is a room with Pain Killers. Kill him and then kill the enemy that is around the corner to the first left. You'll find one more enemy in each bedroom. Once it's safe, check under the bed in the last bedroom on the right just before leaving to find the Business Man. Exit through the back door.
You'll regain control of Max after he drops down into a lower area. As you walk up the alley way. You'll see a couple of men running around and you can kill them if you like. If you linger too long, they'll shoot at you. Make your way until you come to an open area with a large set of steps leading up ahead of you. Kill the men as you climb the stairs and round the corner. Follow this ledge and it will curve left. Follow the curve to find cover and clear the area. Once it's safe, drop down.
After you've dropped down, climb up the far side and you'll be attacked by three men. The first one will be on the balcony of the building on your right and the next two will come running around the corner just beyond that building. Kill them with a Bullet Time/Shoot Dodge and then take cover behind the partial piece of wall along the left side of the alley.
You'll have a few more enemies in this alley but they will mostly be on the upper levels. Clear them out before making your way up the alley. Once you get about halfway up the alley, one man will come flying through a door beneath an overhang on the right and another will come from the alley at the back left. Shoot Dodge to take them out and then take that alley to the left. You'll come to a padlocked door and on the left will be graffiti. Inspect the graffiti for a clue and then shoot the lock off the door. Go inside.
When you regain control of Max, you'll be riding a chain to the top of the warehouse. There is an achievement for killing 9 enemies during this sequence. To do this, there are four enemies on the bottom floor that you must take out very quickly (just go for chest shots since you have the auto-pistol), then you will find two more on a middle level to the right. They should be easy enough. Once they are dead, look far to the left to find the stairs in the distance. Hopefully you've been fast enough that you can't see the top level yet but you can see the man on the stairs. Kill the one man on the stairs and then work your way to the right. There will be another enemy just about to take cover behind the railing just before the corner that you need to kill before he gets there and the last enemy is at that corner in the open. Take him out to get all nine. It might take a couple of tries to get it just right so don't be shy about abusing that checkpoint.
*Achievement: So Much For Being Subtle
Once you land, make your way along this platform and down the stairs at the far side. Hopefully, you've killed these three people already but if not, they shouldn't pose much of a challenge if you use Shoot Dodge. Go down the stairs and into the building on the middle level. Check the far side of this level because it's likely that a couple of enemies appeared even if the other two on this level were killed during your chain ride. Inside this building is a Rifle with a Red Dot Scope. Grab that and use it to clear as many enemies off the far side as you can. There will be two enemies in the middle, two enemies on the left side, and two to three enemies on the right side by the stairs leading up. After you've cleaned it out a little, check the next area before going down the stairs to find part of the Golden Sawn-off tucked away. Go down the stairs to the lower level.
On the bottom floor, more enemies will appear. Take cover behind the giant water heater to your left. There will be one enemy in the middle of the first floor and a couple more that will come down the stairs at the back. Kill them and then climb the stairs. You'll find two more enemies towards the top of those stairs. Kill them and then kill the next two in the room at the top. Make your way through the room and in the next room will be one more. Just by the door to the hallway will be part of the Golden SPAS-15. Go into the hallway and turn left. There will be one more enemy coming out of the room on the right side. Kill him and enter the room. On the desk will be pain killers. Come out of the room and turn right to kill the man at the end of the hallway. You've hit a checkpoint!
Go up the stairs at the back and you'll end up outside again. Go through the giant metal double doors to enter an area with tougher enemies. Just under the man you noticed on patrol will be more Graffiti to examine. Not far from here as you make to leave this area, you will find a stack of wood to the right with part of the Golden SPAS-15 behind it. Make your way through the alleys and when a man with a flare announces your presence, drop down and check near the dead end for the final part of the Golden SPAS-15. Also nearby will be a mural of Claudio the soccer player. Eventually, you will climb some stairs to a destroyed building. You'll be shot at from a similar room across a gap bridged with a wooden walkway.
There will be two enemies initially and when you kill them, two more will enter that room from the left. Kill them all and cross. When you get to the far side, watch for a man with a shotgun hidden around the corner to the left. Hop down the other side and if you follow the right wall, you will find a flyer of Giovanna tucked in a corner. Go through the single nearby door and there will be one man hiding behind an overturned wooden table.
Kill him and take cover behind the white counter to the right. There will be some pain killers on this table while also providing good cover. Two more men will attack from the doorway just to the left of the wooden table. Take them out from here and then go through their room. Going out the other side, a man will exit a door across an alley opposite you. Kill him and then take the alleyway to your right. You'll notice a wooden door on the left wall as you go down the alley. A man with a shotgun will pop out of this when you get close so be ready to Shoot Dodge. Get to the end of the alley and go into the building there.
Immediately turn right as you enter and take cover behind the nearby wall. Take a moment and look up to notice there is an upper level with a couple of gunmen. Kill them and then exit this building through the back. You'll come outside and see a set of stairs with a man on it. Kill him and approach the stairs. At the bottom of the stairs is a small niche to your right that you can't see. There is an enemy there so be sure to take him out as you get to the stairs. Go up the stairs and there will be three men in the room. Use the door frame for cover or (if you feel confident) Shoot Dodge into the room but know that pretty much anywhere you land is going to put you in the middle of a triangle of men with automatic weapons. Cut through the building and exit the back.
When you get outside, turn right and go through the door at the end of the alley. There will be a cutscene where a man comes out of a building and finds you but you'll already be in cover. There will be about six to eight men scattered around there room. Just start with the enemies in the middle and then the right. Work your way left, cleaning them out. You've got a great position even if your view is rather narrow. When you enter the room, just be cautious of enemies behind all the low cover around here. There may be a few men waiting to ambush you. After they are dead, check on the right side of the room on a kitchen counter for a Bag of Oxidado. Try to exit the back of the building and Max will bust it open. And then bust some more things.
Once you control Max again, make your way up the alley again. Keep your eyes open for a Comando Sombra gang tag. You'll find a gated fence at the end on the right. You'll enter and take cover behind a small box. Don't stay here too long because they are going to throw quite a few cocktails and if you get hit by one, you are toast. A cocktail will go over you once, then a second will likely land just to your left. After this, you HAVE to move or the next one will hit you. In the meantime, pop out of cover and try to work your way from right to left, killing enemies. There should be about six enemies visible. After that second cocktail though, immediately start moving to your right and toward the stairs. Just to the left of the stairs will be the last part of the Golden Sawn-off. Grab it and head up the stairs.
When you hit the stairs, there will be one man at the top and then two more in a building in the distance behind him. Kill him and immediately focus on those two. One will be on the middle floor with the other being on the top. Kill them both quickly and move around the right corner. As you round this corner, a man will come charging down the stairs with another not far behind him. Once you hit the top of the stairs, look up to find two more enemies on the rooftops ahead of you. Take cover by the railing to your left once they are dead because you will be shot by enemies across the alley.
Slide along this cover to the right and when you reach the end, someone will shoot a rocket at you. Shoot it quickly to kill him and then jump down into the alley. Run up to where the man with the rocket was. Follow the path as it wraps around the building on the left and go through the front gate to end the chapter.
