Where to Find Infusion #9
The next Infusion is one of the easiest to miss in the game.
From the room where you fought Slate and his men, turn left and head through some white double doors. Then, turn left again toward a workbench with a slightly opened toolbox on it. Jump up onto the bench, and look inside the toolbox to find the Infusion.

The tenth Infusion is one of the easiest to get. Simply look to your right after boarding the First Lady Airship, and it’ll be on a desk along with some Salts.
Where to Find Infusion #11
The next Infusion is found in the Finkton Docks, in one of the holding cells on the lower level.
After defeating the soldiers that take Elizabeth during the main story mission, head to the white double doors on the upper left side of the “Defending Our Values” building. Head through them, and then look for a pile of straw in the cells found inside. The Infusion will be sitting on top of the straw and leaning against the bars.
Where to Find Infusion #12 in BioShock Infinite
For the next Infusion, Proceed through the game until you reach Finkton Proper.
After entering the area, head toward the room with the Main Elevator and then head to the rear left side of the room. There, you’ll find a door that requires five lockpicks to open. If you don’t have enough, there are several scattered around the area that you can find.
Have Elizabeth pick the lock, and then head inside. The Infusion will be to the right on top of a desk.
Where to Find Infusion #13
The 13th Infusion is in the room where Fink tests Booker’s potential as a former Pinkerton with waves of enemies. However, the room won’t be open until after you’ve defeated every enemy.
Once you do, head toward the bottom right corner of the room to find some white double doors below some stairs. Head inside, and the Infusion will be on the right next to a Free Sample sign.
Where to Find Infusion #14 in BioShock Infinite
The next Infusion is hidden behind another Cipher puzzle located in Finkton Proper. The fastest way to get it is to first get the Code Book, and then take it to where the Cipher message is located.
To do this, head toward the lock-up where Chen Lin is being interrogated during the main story mission. Head to the room with the orange Disposal sign and the furnace, and then look for the Code Book sitting on a pile of his business’ signs.
Grab the book, and then head out to Finkton Proper’s main area. Go to the Shantytown entrance, and then make your way up to the far right corner of the area. Here, you’ll find a small passageway leading to a hidden section of the area nestled between two buildings.
Go into the section, and then have Elizabeth pick a lock that requires one lockpick (like with the last lock, there are lockpicks scattered around the area you can use if you’re all out). Head through the opened door, and there will be a Cipher message on the wall next to some clocks.
Once deciphered, the message will refer to a clock tolling at midnight. Interact with the clock just to the right of the message, and it will reveal a hidden compartment housing the Infusion.
