Navigating S.T.A.L.K.E.R. 2: Heart of Chornobyl involves crucial decisions impacting gameplay. The mission "Just Like the Good Old Days" follows either "To the Last Drop of Blood" or "Law and Order," culminating in an escape from the SIRCAA.
Proceed to the mission marker on Wild Island to locate Professor Lodochka at Quite's Camp. Expect an immediate priority objective: eliminating mercenaries. These enemies will be clearly marked on your map.
Equip yourself well; this isn't the only encounter. Eliminate all marked mercenaries to access Professor Lodochka. An optional objective, "Activate the Ventilation System," will then become available.
Consult your map for the fuse location. After retrieving it, another marker will appear, guiding you to the engineering rooms. Be prepared for an invisible enemy within.
Navigate the shelter to the engine room and use the fuse to restore power to the ventilation system. This simplifies the remainder of the mission, although it doesn't offer unique rewards.
Consider acquiring better weaponry before proceeding. Locate the cave entrance near the water. Navigate the caverns westward, descending and overcoming obstacles. Use a broken pipe to reach higher cave levels.
Find the large cone-shaped spire; the emitter is located at the marked point nearby. An invisible enemy awaits on your return journey. Report back to Professor Lodochka to complete the mission and unlock "Hornet's Nest."
