The Boiler Room
After a brief respite, you'll find yourself in the Boiler Room, a cramped and steamy area that serves as a crucial bottleneck before deeper exploration of the Factory. This section is characterized by its tight corridors, steam vents, and the constant threat of ambush. Your primary objective here is to navigate through the industrial machinery and find a way to proceed to the next area, which often involves manipulating environmental elements.
Upon entering, immediately be on alert for a Soldat Jet or Soldat Panzer. These enemies thrive in confined spaces, so prioritize headshots and utilize any explosive barrels you might spot. The Boiler Room also contains several steam pipes that can temporarily block your path or obscure enemy vision. Look for valves to shut off the steam, but be wary as this might also reveal hidden enemies. There are often a few crafting materials and shotgun shells scattered around the machinery, so keep your eyes peeled.
