Chapter 16: Return to Deathshead’s Compound
5:7: Just after you enter the compound, go down the first hallway lined with statues and enter the room at the very end. Go left and you will find this code sticking out of a filing cabinet there.
5:8: After the first large fight in the large room, go down the circular stairs on the left and you will enter a circular room. Go through it into the next large room and look for the code on the bench in the centre.
5:9: After the previous large room, go through the metal door and you will enter a lab. Go to the far left side to find this on a table against the wall.
