The research facility is a fortified location, often guarded by a small contingent of hostile stalkers or a pack of aggressive mutants. Approach from a less obvious angle, using environmental cover to your advantage. Look for alternative entry points like broken fences or maintenance tunnels, which might bypass the main entrance's defenses.
Once inside, the facility will be dark and labyrinthine. Use your flashlight sparingly to avoid detection. The primary objective is to reach the central laboratory, which is usually located on a lower level or in a heavily secured section. Expect to encounter 'Snorks' and 'Bloodsuckers' in the darker corridors. Listen for their distinctive sounds to anticipate their attacks. Activating circuit breakers or finding keycards might be necessary to progress through locked doors.
