Suggested player route
Suggested kill areas
After you start this chapter, crouch and walk through the window to the left.
Once you take several steps, you will have to walk out into the corridor through the widow to the right. Wait for 2-3 seconds, next to the toilet, for the enemies to walk away.
Walk from the corridor to the room opposite and leave it through the window on the right. On the left, there are two soldiers with flashlights. To avoid the light, hide quickly behind a cover and climb into another room through the window. You can now walk around the two soldiers and turn right in the room at the other end of the corridor.
Avoid the light from another pair of soldiers and go ahead, up until the long passageway between the hospital sections.
You will notice a tabletop to the right, which you should quickly hide behind. This way you will avoid another Firefly patrol.
As soon as the soldiers run away, walk out of your hiding place and go ahead. In the next room, you will be attacked by a single enemy which you need to shoot.
Once the man dies, walk through the door opened ajar and barricade it from the other side. You are now relatively safe. After you climb up the stairs, you will see a tabletop ahead of you, with a locked room behind.
Use your knife to open it and run ahead. This way, you will reach a place where you should press L3. Joel will notice another soldier unit then.
To avoid getting into fight, sneak through, as far away from the beam of the soldier's flashlight , and keep to the right side of the location then.
When you encounter another enemy, wait for him t turn away and go ahead as quickly as possible.
The next one is waiting a few steps ahead. He should be standing back to you but, only for a short moment. Before he turns, hide behind the cover next to the door. After several seconds, you will be able o leave the room and go ahead. As soon as you notice a wide entrance, jump over the barricade to the left and leave this location.
At the other side, there is a long corridor which will lead you to the operating room. Kill the doctor that stands in your way and take Ellie from the table.
You now need to run, while carrying the girl, ahead, and avoid the soldiers that you get past.
Once you enter the elevator, the chapter will conclude.
