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," concluding with 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 identifiable, foregoing any need for searching.
Strong equipment is advisable, as further encounters await. Eliminate all hostiles 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. Be prepared for an invisible enemy within.
Enter the shelter, navigate the passageways to the engine room, and use the fuse to restore power to the ventilation system. While this optional objective doesn't offer unique rewards, it simplifies subsequent mission steps.
Consider upgrading your weaponry before proceeding. Locate the marked cave entrance near the water. Navigate the caverns westward, descending and overcoming obstacles. A broken pipe provides access to higher cave levels.
Find the large cone-shaped spire; the emitter is located at the marked point beside it. An invisible enemy will likely ambush you on your exit. Return to Lodochka to complete the mission, unlocking "Hornet's Nest" as the next main objective.
