Last update: 11 May 2016
When you get to the mech and can control your character again, destroy the gate and deal with the charging zombies. If one of the enemies manages to jump at the mech, you have to go outside and kill it, otherwise it will kill you.
When you get to the second bridge, go out of the mech and shoot down the ropes holding the drawbridge. Before you go back to the mech, dive into the water on the right side of the bridge to find a piece of gold on the bottom.
After picking that up use the mech to destroy the gate and proceed to the next location. Deal with the zombies charging at you, then leave the mech and start sweeping the area.
First, collect the map on the right. As soon as you can jump into the water and dive, in order to get to a narrow passage you can swim through. When you get out to the surface on the other side, you will see the map lying there.
Go back to the mech and move through the next parts of the location. Destroy all gates, and by no means leave the mech behind. The next gate must be opened manually. Enter the small, stone room and pull the lever in there. Before you head back to the mech, pick up the letter on the table on the right.
After finding all the collectibles here, go back into the mech and destroy the wooden gate blocking your way. On the other side, you will find a building on the left and a metal gate. This can be opened only with the key lying on the table in the aforementioned room.
When you open the gate, be ready for an endless wave of zombies. Try to eliminate them by headshooting them with your rifle, and when it gets safe, proceed to the next part of the location.
You have reach another lever on the opposite site. Smash through more zombies, and when you manage to open the gate for the mech, get inside it and follow the left corridor to the next gate. Destroy all the enemies on your way, and at the end approach the passage seen in the picture to conclude the seventh chapter.
