Let's continue with the solution of The Last of Us in Bill's City:
1 - The forest
Continue straight into the forest, examine the grate on the right to collect some useful items. Continue on the path to the base of the water tank. Follow the fence to the left to collect the wooden plank; lean it against the building behind you, climb onto the roof by climbing on the air conditioner motor and take it back in your hand, to place it over the fence and pass it. Before continuing any further, pick up the melee weapon on the roof of the building you are standing on.
Go down the hill leaving the cistern behind you, then look for the hole in the fence to enter the city. There is a Clicker in the shed, be careful. Go up the metal stairs; enter the room at the top (the one full of computers) to collect a collectible.
There are two more in the area, so pay attention. Jump down the stairs and help Ellie get over the fence to get the iron door open for you to continue. First you will find another one, to be opened by sacrificing a pair of scissors: do it to collect a series of useful objects.
Once you get through the door Ellie opens, you will find more, especially in the garden area. Some are in the pizzeria, where as you approach the video game machine you will witness an optional dialogue between Ellie and Joel. Continue your exploration and collect more items by examining the area around the blue waste bin behind the pizzeria, and the landing at the top of the staircase.
Climb into the Jeep and pick up the Lights Tag, then the collectible along the fence with the barbed wire. Now go back to the street and approach the restaurant, where, next to the pickup truck, you will find a safe with items and ammunition.
Now go to the record shop to collect more things, then to the back to see one of Bill's traps in action: an enemy will approach and explode after touching a wire. Be careful of these along the way, if you have a pair of scissors use it to open the door then continue. You will find a corpse with arrows in its body: collect them and continue, take the ladder and place it on the truck to get on it. On the roof of the vehicle, collect the bow and another arrow, to be used immediately once you reach the one in front.
Once you take out the Clicker, jump off the roof and go under one of Bill's traps, heading towards the church and the column of smoke. You will come across a door beyond which there will clearly be an enemy: open it and go up the stairs to collide with the runner on the second floor, then take everything you can find. Go back to the street and continue, throwing a bottle or a brick at the two traps you will encounter. Keep going and avoid a third one, near the green sofa in the grass.
Now enter the red brick building and you will find yourself hanging upside down in yet another trap. Shoot the zombies to keep them away from you and Ellie. You will have to survive against multiple waves of monsters before Bill arrives to save you. Now start running to the next room. Complete the frantic sequence to reach a safe place.
2 - The Refuge
Watch the cutscene (we dare you not to laugh at the bickering between Ellie and Bill), then gather everything you can, paying particular attention to the collectibles and the manual to improve Joel's skills. Approaching the board you will see an optional dialogue. Once you're done, follow Bill up the stairs and grab whatever you find. Keep following the man to the street, where you will be attacked by a large number of infected. Throw a brick or bottle on the glittering street lamp to drop and collect the Lights tag. Now keep following the NPC until you drop under the house, where you can pick up the shotgun.
Approach him and talk to him to get a nail bomb. Collect everything and upgrade your weapons at the nearby work table. When you are ready you can go up the stairs and follow Bill into the church.
3 - The cemetery
In the church, before exiting, check the room on the right to collect. Use the window and get ready for a long stealth phase: you will have to go through a graveyard full of Clickers, so it will be better to use a silent approach rather than fighting with firearms. Once you leave you will have to head towards the school, and even in this case it will be better to do it silently: use the scissors that will be left to take out the monsters, while normal runners can be strangled as usual without too much effort.
In the garden on the right there are three infected: pass them to enter the house, where in the laundry room next to the kitchen you will find a plate of the Lights. Go through the garage and continue. Wait for Ellie to go through the dog door and open the passage for you. Once you get out, get ready to take out some Clicker and rake everything. Then continue with Bill's plan: enter, take the battery and escape as quickly as possible. Once outside, go up to the tree house and use it as a passage to reach the next garden, the one with the swimming pool.
You have almost reached the school, which is on the other side of the house you will enter. Before continuing, examine all the rooms, including the one upstairs where you can witness an additional dialogue with Ellie. Once you have everything, go to the garage and help Bill raise the overhead door. Kill the infected and go straight, help the girl get on the bus and get on too. The main door of the school will be closed, so you will have to follow it and go around the structure until you find the window open and enter from there.
4 - The school
The plan to recover the battery will be a disaster. Follow Bill into the school and kill all the enemies in the science class, possibly in stealth mode. Open the gym door and prepare to face the toughest of the infected, the Bloater. You will be able to easily get the better of this enemy using the Molotov cocktails, while with the pistol or (better) the shotgun, it will serve to keep the minor enemies that will attack you at bay. Once killed, help Bill and Ellie up the bleachers, then get ready to repel the last runner attack before continuing.
Exit the window and go back to the street, then you will find a hole in the fence and go through it. Enter the house where you collect everything you will find, including the letter from Frank which will allow you to witness a dialogue between Joel and Bill. Once ready, get Ellie into the car and start pushing. Every 50 meters or so you will be attacked by a group of infected, until the engine starts.
