Groznyj Grad is the heavily fortified GRU fortress, the heart of Volgin's operations and the location of the Shagohod. This is arguably the most challenging stealth section of the game. The base is sprawling, with multiple sectors, guard patrols, searchlights, and even tanks. Your primary objective is to locate Sokolov and then find a way to destroy the Shagohod. You'll need to be extremely patient and methodical in your approach. Utilize the 'Scientist' or 'Officer' uniform (if acquired) to move more freely, but always be wary of suspicious behavior. The base also contains a prison cell where you'll be held captive at one point, requiring a clever escape.
