After you regain control of Blazkowicz, grab any ammo in the area and head out of the boathouse. There are guards patrolling this area, so be careful as you move around. We suggest taking out the two soldiers patrolling across the river (leave the Heavy Soldier alive), as well as the soldier and the Commander on this side of the dock. Once these normal soldiers are dead, head to the first opening on side of the dock beside where you entered. Here you can drop into the water and swim past the Heavy Soldier to a ladder near where he patrols. Climb out when he isn’t looking and move as quickly as you can to the archway on the far left side of the dock. This will lead to a large winding staircase.
Drop into the water, then continue up the staircase to the next area. There are a couple of guards up here, so take them out and continue over the wooden bridge and into the building. Once the enemies here are dead, continue up the stairs and drop out of the window on the upper floor.
This next part requires a lot of stealth. If you choose, you can go in guns blazing, but there are two Supersoldiers, two Commanders, and a batch of regular Nazi scum roaming about in this area.
If you choose not to waste all your ammo in this area, continue past the first option (from where you dropped out of the window) and all the way to the right. Turn left right here, then head up the small steps, waiting until after the Supersoldier walks away to drop onto the ledge below. When you have another chance, make your way to the ladder in the middle gazebo and climb up.
This is where things get tricky. After you reach the top of the ladder, locate the window with the zipline. It should be the first one to the right of the ladder. Wait for a clear shot, then take out the soldier Commander that is patrolling the ledge across from you. Once he is dead, and you have another opportunity, zipline across and drop down.
Follow the path down the stairs to the corner, turn left, then continue to your right to find the entrance to the Baker’s shop. Interact with the door, then after being told what to do, interact with the rock on the ground to the right of the steps.
Take the key, open the gate, then head around the back of the house and climb in through the basement window using your Pipes. This will trigger a cut scene, and once you’re inside you can move around a little. Enjoy the banter as it plays out, grab Wesley’s letter off the desk, then scoop up the Gold Collectible hiding in the corner by the pipe.
After Pippa (Agent Two) gives you the information, interact with the chest to find some clothes. Once you’ve picked them up, Blazkowicz will deposit all his guns into the chest, then you’ll need to wait for Pippa to ask for help with the hatch in the floor.
Drop through the door and into the water below. Swim forward until you reach the well at the end, then climb up the wall using your Pipes. You aren’t in the clear here, so watch out for the two hounds sleeping in the yard. Take the one in front of you out, then the second one to the left if you wish. Step up to the tavern’s door and head inside.
This will place you in the kitchen. The whole point of this part is to pretend to be a waiter so you can get close to Helga. To do this, you’ll need an Apron and a Serving Tray. You can find both of these items near a wooden shuttered window on the opposite wall from where you entered. Once you’ve interacted with both of them, head out the door into the main area.
Ignore the Nazis around you. Your objective is located on the second floor, so you’ll need to head up the stairs. As you go, a couple of Nazis above will get into a scuffle. Wait it out, and once the door is closed again, sneak on past them with your disguise. Continue forward until a soldier calls you over to give Helga her wine, then move into her room.
Set the tray on the desk by interacting with it. You'll have several more bits of interaction in this chapter, but you merely need to follow the on-screen prompts to get through. Since we don't want to spoil things for you, we'll let the chapter play out naturally.
You can continue directly to Wolfenstein: The Old Blood Part Two - Chapter Six: Ruins, or you can return to our main Wolfenstein: The Old Blood walkthrough. It's there you'll find all of the chapters, boss fights and collectibles the game has to offer.
