This page of the guide has a walkthrough for chapter 19 of Uncharted 2: Among Thieves called Siege. This chapter takes place in the village attacked by the mercenaries. Enemies will have a huge advantage and use heavier equipment. They will also occupy the roofs and other hard-to-reach places.
After a long break, we return to killing the mercenaries. Chapter 19 has a huge number of opponents. The entire level is one big battle.
You can also get three treasures. They aren't that difficult to find but due to the chaos in this chapter, these treasures are easy to overlook.
Difficulty level: medium
Number of opponents: huge
Chapter type: combat
You start in the building. Leave it and prepare for a fight.
Don't rush forward - take your time to eliminate all the oncoming opponents. Some enemies are located on the roofs, others will attack you from the ground. Kill them one at a time. You will be attacked by an enemy with a slightly better armor and a shotgun - kill him from the distance.
When everyone is dead, collect ammo and grenades, and then head down the hill toward the brick arc.
The pictures shown above show this place. This is a great position - you have to defeat a lot of opponents. The picture on the left shows the left side of the square, with the machine gun on one of the roofs. The picture on the right shows the building in front of you [secret 1] - there are several enemies inside it. Kill a few enemies and head to that place (a good idea is to throw grenades inside it).
Get inside the building to have a great position to attack the enemy using the machine gun. Run towards that enemy while he is focused on shooting the villagers. Reach that enemy and kill him. If you play on a harder difficulty level, you will have to hide behind a few covers before reaching him.
After that, use the turret to kill the approaching enemies. They will appear on the street and on the roof to the left.
Go through the open gate, the one used by the enemies a moment ago. You will be attacked by an enemy using a rocket launcher. Drake will automatically land behind a fragment of concrete structure. Kill the enemy equipped with a rocket launcher first. He is located farther away, on one of the roofs. One of the enemies is waring armor and uses a shotgun - don't let him get closer to you.
When all enemies are dead, follow your companion.
You will get to the building. Get inside and defeat yet another mercenary. This enemy has a shotgun, and the room is relatively small. The best way to take him down is to shoot him before you get inside the building. When you approach the first ladder, one of the opponents waiting at the top will throw a grenade - when this happens, move away for a moment.
Climb the two ladders to reach the rooftop. This marks the beginning of the last and biggest battle [secret 1] [secret 2]. This fight isn't the most difficult, but you need to remember a few important aspects. First, the opponents will attack from almost all sides. Second, never leave the roof, always attack from above. Third, be aware that the opponents can attack you from behind by climbing up the ladders.
Don't stand too long in one spot, jump from one roof to another. One of the enemies standing farther away to the right has a grenade launcher. Kill him as soon as he opens fire.
The building with blue trapdoor has a machine gun. Use it to kill the enemies faster.
Go down to the ground floor and head to the place where the enemy with a grenade launcher stood. You will reach Tenzin's house. Go inside and finish the chapter.
