Floor B2 (Electrical)
You will start exploring floor B2 of the factory at the top of the Grinder Shaft, which is where you turned off the big working blade after dealing with the flying Soldat Jet enemies.
Use the only available exit from the area with the shaft. In the next room, you will find the Factory Map (Upper Levels). You may optionally push aside the wagon pictured above. This will unlock access to the tunnel leading to the side room. The most important object you'll find there is the Ball Mold. You can use it to create a ball in the Casting Mold on floor MB4 and then solve the Labyrinth Puzzle next to the elevator with Duke on floor B4.
Reach the large Ventilation Duct. The hero will be sucked into the duct. You have to quickly hit the red reactor located in the middle of the giant working fan to get out alive.
Reach the elevator traveling to level B1.
Floor B1 (Storage) - Finding the Key Mold
You will discover something important shortly after you start exploring floor B1. In one of the first rooms, you will come across a Key Mold.
Continue following the linear path until you reach the balconies with the elevator shaft. Summon the cargo elevator to floor B1. Ride the elevator to floor B4.
Floor MB4 (Materials) - creating Heisenberg's Key
Once you have acquired the key, you must once again reach the Casting Machine, which as a reminder is located on the MB4 floor. Place the recently acquired Key Mold in front of it to create the Heisenberg's Key.
Reminder - If you also found the Ball Mold on level B2, you can additionally create an Iron Horse Ball, which you can use to solve the Labyrinth Puzzle on floor B4, next to the elevator.
Where to use Heisenberg's Key
You can use the newly acquired key in two locations. Visiting Heisenberg's Quarters on floor MB4 (pictured above) is optional. Some regular monsters will be inside and once you have disposed of them, you will find lots of minor loot and the Mechanical Part (Shaft) treasure, which can be combined with the Mechanical Part (Cylinder) treasure found in a different part of the factory.
You are required to bring the key to the door on level B1, which is located next to the cargo elevator with Duke (pictured above).
This will allow you to progress the game and reach the battle with the first of the two factory bosses.
Fighting the Panzer Soldat super soldiers
Unfortunately, on the way from the casting machine to the elevator traveling to level B1, you will encounter two Soldat Panzer supersoldiers - this is the strongest among the "standard" varieties of these enemies.
You have two options here:
- If you want to fight the Panzers, use a grenade launcher first and aim at their front armor. Only once the chest armor is destroyed will the red core be revealed, which you can target to defeat the monster.
- If you want to avoid a fight, you will unfortunately have to retreat to a wider location and wait for the Panzer to arrive. These are very large enemies that by default will occupy the entire width of the corridors where they appear. Pass by the Panzer while they are finishing one of their slow attacks.
