Chapter 4 - Three Fragments of Code | Ada's campaign Resident Evil 6 Guide
Last update: 11 May 2016
In order to obtain the first code, turn around and enter the cabin on the right. You'll encounter there one J'avo, which has the key-card.
Go through the nearby hatch and move forwards. At the very end of the corridor turn right.
You'll reach the flames, where two breaking up mutants will attack you.
Kill the first one by pressing A and use the crossbow to get rid of the second one. When the water extinguishes the fire, move forwards. In the long corridor you'll be attacked by a large group of enemies. After the fight explore the nearby cabins. You'll find there some useful items.
Once the area is clear, go through the hatch with a yellow lever and then enter the canteen on the right.
On the other side you'll find the corridor - go forwards, until you'll see a cabin door on the right.
Quickly get inside, kill enemies and try to pick up the key dropped by J'avo with yellow eyes. Unfortunately moments later it will be stolen by a mutant sliding through the ventilation shaft. You have to wait until the beast comes back and scan the code.
Once you're done return to the corridor and then turn right twice. You'll reach that way the wooden door leading to the luxury cabin.
Inside the cabin kill opponents and pick up the machine gun lying on the table.
You can now return to the corridor with many cabins and head to the place with red glow. There is a door leading to the cabin.
Inside you'll find an enemy with the last passcode.
Take it from him and open the lock.
