Getting through this part isn't as tough as it seems, just need a smart approach. Starting off make some saves since things can get intense pretty quick. Before diving too deep, take time to scout out guard movements from a safe spot using scopes or binoculars, really helps avoid nasty surprises. Getting your hands on an OZK Explorer Suit makes a huge difference, since it'll keep you safe from those random anomalies that pop up everywhere.

When you're moving through the guarded areas, stay quiet and use suppressors whenever possible, guards will definitely investigate noise but you'll be long gone if you relocate after each shot. Those bolts are actually super useful, toss them ahead to trigger anomalies safely while staying in cover. The rats on the catwalks can be tricky, but if you keep moving and use rapid-fire weapons while staying near exits, they're manageable. Just remember to stock up on medkits and bandages since those little guys love making you bleed.

Tip that might help - treat each new area like its own little mission instead of rushing through. Breaking it down into smaller chunks really helps keep your head clear when things get chaotic, especially in those tight ventilation shafts and near security gates.
