Upon reaching the final approach to the 'Heart of Chornobyl', you will face the fanatical forces of the Monolith. These are highly trained and heavily armed stalkers, often equipped with advanced weaponry and armor. They will utilize cover, suppressive fire, and coordinated tactics. This will be a prolonged and intense firefight.

Prioritize targets: snipers, grenadiers, and heavy weapon users. Use your own grenades and explosives to flush them out of cover. Look for environmental hazards that can be exploited. After clearing the initial defenses, you'll likely encounter a series of fortified positions leading to the central chamber. Be prepared for traps and ambushes. This segment is a test of your combat prowess and tactical thinking.
