BioShock Infinite The Plaza of Zeal is considered to be Chapter 18 of the video game, but it acts as a hub from where the player can start other missions.
The Plaza of Zeal is opened after DeWitt and Elizabeth use the service elevator they find in Finkton Proper.
While in the plaza, they must search for a gunshop that belongs to a character named Chen Lin.
Since the plaza is a larger area than usual, with many paths to follow, it is recommended to use the following BioShock Infinite collectibles guide in order to find all the secrets and collectibles.
When you arrive in the plaza, the first thing you should do is start the optional quest, because later in the game it will lead to a hidden collectible.
In order to do that, turn right and go around the corner to find a locked door (The Clock Shop). Go inside near the code to activate the quest (the code book can be found in the building named Good Time Club).
Go back outside and walk forward, pass the police security checkpoint (this makes the enemies attack you, so deal with them first).
Near the Good Time Club there are some train cars filled with logs. If you go pass them, in the corner you can find the first BioShock Infinite The Plaza of Zeal Voxophone next to a saw (this area is the north-east point of the plaza, considering your starting position).

You can access the Good Time Club now, but its best that you visit it later, when the story leads you here, since there isnt much to do now in there. Search for Chen Lins gunshop and go inside.
As soon as you enter look on the counter for the second BioShock Infinite The Plaza of Zeal Voxophone (you need to collect it before opening the next door).

After that, open the door to leave the area and start the chapter known as The Gunsmith Shop.
However, this chapter doesn’t feature any BioShock Infinite collectibles, because as you progress through the game inside the shop (detailed in the next part of our guide), you need to get to The Good Time Club.
