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 Wild Island mission marker, locating Professor Lodochka at Quite's Camp. Expect an immediate priority: eliminating mercenaries marked on your map. These enemies are readily visible, eliminating the need for searching.
Equip yourself well; this isn't the only encounter. Eliminate all mercenaries to reveal Lodochka's location. An optional objective, "Activate the Ventilation System," will then become available.
Consult your map for a fuse location. After retrieving it, another marker will appear to the north, leading to the engineering rooms. Beware an invisible enemy within.
Navigate the shelter passages to the Engine Room. Use the fuse to restore power to the Ventilation System, facilitating mission progression. While this optional objective doesn't provide unique rewards, it simplifies the main mission.
It's advisable to acquire superior weaponry before proceeding. Locate the marked cave entrance near the water. Navigate the caverns westward, descending and traversing obstacles. A broken pipe provides access to higher cave levels.
Follow the marker to a large cone-shaped spire. The Emitter is located at the marked point beside it. An invisible enemy awaits on your return journey. Finally, report back to Professor Lodochka to complete the mission, unlocking "Hornet's Nest" as the next main objective.
