Stalker: Shadow of Chernobyl → Underground
Down below, you'll be warmly greeted by bandits. Avoid the electrical anomalies—descend the spiral staircase to the lower level, a realm of cheerful green lights, filled with witch's jelly, and inquisitive bloodsuckers. First, a rapid-fire AK-74, the one and only. Second, a flash drive containing information about Strelok. It will lead you to a stalker named Prizrak, one of Strelok's comrades.
Carefully move further underground and prepare to encounter the game's first controller. If you have grenades, good. If not, you can survive. Wait until evening (you might have to go have some tea), and emerge from underground. You are inside the perimeter of the research center, and your goal is to steal the coveted briefcase from the third floor. Continue to the surface of the Agroprom Research Institute.
