Chapter 4 - The Triple Lock | Chris's campaign Resident Evil 6 Guide
Last update: 11 May 2016
Once you get to the destination, move to the lock blocking the door. You need three electronic keys to unlock it.
First one can be found in a room a bit further. Pick it up and then open the door to the right.
Prepare for the fight with two beasts met in Leon's campaign. These creatures split themselves into pieces after being shot and can reborn even after destroying each element.
Once you get rid of them, open the door to the right and enter the ship kitchen. A third opponent will appear. You have to stick with him in one room until fire alarm goes down.
After that leave the room and move forwards. You'll reach a long corridor. You have to turn right and then enter the first room on the right.
Once you start opening the door, Chris will be dragged to the other side by a mutant. Kill him and take a second electronic key lying nearby.
You can now leave the room and move to find the last keycard. So go back to the corridor, turn right and go down the stairs to a lower level.
You'll reach a corridor leading to several rooms. The last key card can be found in the penultimate room on the right.
Now you can return to the upper floor and unlock the gate.
