One of the first data bios that players will encounter will be in chapter one when you have the objective of checking on the special cargo. Open the door into the main hallway, and players will be in a room that will have a few beds, as well as two main lockers that will be present in front.
Start walking up to the lockers, and you will encounter a locker to your left that you can easily open up. Press E to interact with it in order to open up, and you will get the Jacob Lee: Jacob’s Job data bio.
As for the second one, you will be able to encounter it in chapter two, “outbreak,” when you have the objective of “find the weapons lockup.” You will need to go to a room with “surgery M112” written on it.
Enter the room and head past the operation table, and go past a door that is unlocked on a small yellow ledge; you will find Caitlyn Mahler Mahler’s Appointment data bio present.
In order to find the third one, players will need to be progressing through the second chapter, which is an outbreak. Players will need to get to the objective whereby. It tells them to make their way over the back to the watch tower.
From the main hallway, start running forward until you’re able to encounter a small door that is open in front of the smoke that you just crossed. From there, head into the cellblock that is labeled above, jump over some boxes, and turn right to enter a cell, and it will be present inside.
Captain Leon Ferris
Another one that players will be able to find in chapter two will belong to Captain Leon Ferris, and in order to get that, players will need to be at the objective, which tells them to find a certain exit.
You will be behind a few glass windows overlooking enemies inside that will be attacking a person in a flashback. Head inside the room, and the data bio will be on the futuristic center table.
Sergeant Eric Jane
To get the next data bio, players need to have progressed enough to get to the aftermath chapter, whereby they will have an objective that tells them to find a guard’s corpse.
While being inside a vent, start moving forward, and jump out of it, where there will be a malfunctioning guard. A dead person will be lying on the ground, and you can access the data bio by pulling it out of his neck.
Officer Pruitt Matos
For the next data bio, players won’t need to go anywhere else, as they will need to head past the lifeless guard that had SGT Eric Jane’s data bio and start making their way past the boxes that are present in front.
Move forward, enter the laundry area, and turn right from a corner; an enemy will attack you there. Head into the next door that is unlocked, and keep making your way to the end and into the office.
To get the Duncan Cole data bio, start heading back from where you got Pruitt’s bio, and you need to turn right from a few boxes, which will then start leading you up. Run past the two doors that say unlocked, and then start making your way down.
