Follow Wesley into the building, down the steps and through the turnstile to the desk clerk. As soon as the cut scene ends (Rudi Jäger laughs at your impromptu joke and hands you back your papers), go through the second turnstile and turn around to look back the way you came. There is a key on the counter to your left. Pick it up.



Get into the elevator with Wesley and follow him out to where a cable car is waiting. Do not go into the cable car yet. Go to the gate and open it (the purpose of the key you picked up) to go down the stairs into a secret area.



Go over to the bed on the floor and click to activate the nightmare.








Note:
Instead of exiting the maze here, rather find the hidden elevator that takes you to the upper level of the maze where a lot of Old Silver is still to be found.

In this part of the maze you will find a lot of health packs. Some of these are arranged to spell out the letters "MG". It stands for MachineGames, the developer of the game -- my thanks goes to Españoleitor tres mil for pointing that out. A total of 180 health points are available here. Unfortunately, these cannot be used to obtain health upgrade perks -- thanks to The Darius for reporting this.

As you progress through the prison, you'll get to talk to a prisoner called Markus who mistakes you for his son. As soon as this happens, know that the nightmare bed is quite near.











Continue to the nearby gate and use sprint-slide to get past it. Now enter the circular hall where several prisoners are sitting and walking about. Find the open prison cell with the two stacked beds and a hatch in the floor beside them.











Open the hatch and jump down onto the stacked beds below. Get down to the floor. The bottom bed of these two is the chapter's nightmare bed. Click on it to activate the nightmare maze.

After escaping from prison, get down from the balcony (where you forced the switch) back into the cable boat and continue the trip into the next area. Shortly after entering, you will come under heavy enemy fire. Take care of the enemy while still in the boat as well as after you have disembarked.

Notice the other cable boat on the other side of the dock? That will take you directly to another balcony with a switch AND the next nightmare bed. (In the meanwhile you can explore the surroundings, get into the right-hand side upper level of the keep by pulling a lever, going through a gate and climbing up a wall, then down again to eventually end up at this docking area again.) Get into this second cable boat and take the short trip to the second balcony.



Go through the gate and get up onto the balcony when the boat stops. Before you pull the switch, locate the nightmare bed on the right-hand side of the balcony and click to activate the nightmare maze.

Once you reach the dining hall, you are in close vicinity to the chapter's nightmare bed. A long table is set in the middle of the floor, with a fireplace burning at the far end. The area is patrolled by Nazis. After taking care of the enemy, go to the left-hand side of the room (as you entered) where there is a kitchen and pantry area. Continue further in until you get to a closed trellis-gate. When you stand close to it, a prompt will tell you that it's opened from the other side. This is the secret area that contains the nightmare bed.











To get to that secret area you must first climb the stairs to the upper level of the dining room, where you go to the side of the room the closed gate is on. Locate a hatch in the wall around the corner (far left corner of the upper level as you entered the dining hall). Open the hatch and climb through it.











At the opposite side of the little room there's a weak spot in the wall where you can break through and continue the game. However, before you do that, notice the lower area beneath the wooden support on your right. This is the secret area where the nightmare bed is. So jump over the side to the bottom part.











With the closed gate on your left (you can now open it from this side), go to the nightmare bed in the corner and click to activate the nightmare maze.

This nightmare bed is located in the Paderborn tavern where you meet up with Annette and Kessler for the first time in the game. After meeting the village drunk (also for the first time) and, maybe, giving him some coins for soup, go around the building to the tavern door and knock.











Follow Annette into the tavern, but don't go into the room where Kessler is yet, otherwise you will miss the bed. Instead, go up the stairs on the left as you entered the building.











The nightmare bed is to be found at the top of this staircase. Click on it to activate the nightmare maze.

After dealing with the two Nazi commanders, two super soldiers and a few regular soldiers in the Wulfburg square, you jump down from a roof into an alley that leads past a brown sign hanging on your left that reads "Bierstube" ("Beer room"). Continue down the alley until you get to the village drunk for the second time, who is very glad to see his old friend again.











After the drunk quiets down and goes to sleep, continue on to the left, where you will find the nightmare bed in the corner behind a broken old pick-up. Before you turn to the right to go to Agent Two's house, click on the bed to activate the nightmare maze.

You are on your way to meet up with Kessler and Annette again, but they are not at the boat house. You acquire a shotgun and upon exiting the boat house you deal with several Nazi zombis that have rained down from the sky in the area. Much of the area is ablaze, also the airships above. You continue to the left of this docking area where you have previously taken care of some Nazis and their commanders.











There now is a gap where earlier on the way was barred. Jump into the water and swim to the once inaccessible part of the area. To your left you will see a shop sign reading "Schmiede" ("Blacksmith") and a bit further you will encounter a detached water-wheel from a mill.











The chapter's nightmare bed is in the gap where this water-wheel is. Get in there and click to activate the nightmare maze.

From the start of the level, use the Laderoboter to break down the gate in front of you. (You can also explore this area before bashing down the gate - press 'C' (default) to exit the machine.) On the other side, exit the machine and shoot the ropes attached to the drawbridge to your left so you can access the next large gate. Get back into the machine and also break down that gate with it. There is a bridge in front of you with a Nazi fighting off some zombis. Kill them all and exit the machine again. Facing the bridge the way you entered this area, notice the broken wooden walkway across the water on your left (just before crossing the bridge). This is where you need to go.











Jump into the water here and swim to any of the two brick archways on the right. Continue through to the other side, where you can get out of the water.











Once you get onto dry land, go to your right, where you will find the chapter's nightmare bed in the corner behind some boxes, next to another brick archway. Click to access the nightmare maze.

After going down a floor using a cage-elevator, duck behind a mining cart to avoid being spotted by a super soldier. Once he turns to walk back in the opposite direction, follow him to where you turn into a doorway on your left. (After getting out of the elevator, you may explore the screened-off area to your right, but avoid being seen by the super soldier.) You enter a tunnel with a large yellow funnel running alongside you. It ends when you get to a fenched-off area where there is a table with some grenades on it and a skeleton sitting next to a locked wooden door. This is the area containing the nightmare bed, but you can not access it from this side.











For now, you have to move deeper into the dig site, either avoiding enemies or taking them out as you go. So continue past that closed door to the junction, where you turn to the left, following the tram lines. Up ahead is a door that opens by holding down a lever and then prying it open with your multi-purpose piece of pipe.











On the other side of the door you enter a room with three Nazi soldiers who are shooting at some zombis through windows. They all have their backs turned to you, so take them out stealthily (or not). Two rooms lead out from this one: one to your left and one to your right (as you entered). To get to the nightmare bed, go up the steps on the left and immediately turn left again. You will see some stairs with a hole going down right through them. Go through that hole.











You are now in a small chamber with only one small exit: a narrow rectangular window that will take you into the secret area with the nightmare bed. Tuck in your stomach and climb through to the other side. Now click on the bed to activate the last nightmare maze. (The locked door will now open to let you continue the chapter and finish the game.)
















Congratulations! If you have followed this guide to the letter and pixel, you have now completed all the nightmare mazes and collected all the old silver!
