Stalker: Shadow of Chernobyl → Research Institute "Agroprom" (Part 1)
The research institute area is controlled by soldiers—you'll constantly encounter patrols on the road. Beyond the institute's gates, stalkers battle the military. Help Mole's group, and he'll show you the entrance to the sewer system where Strelok once stored his valuables.
Before you venture into the dungeon, be sure to find at least one silent pistol—you'll need stealth very soon. Let's go down to the underground.
