Elsa's last day

Last Day has kidnapped Elsa, Sakharov's wife, yet again. He advises us to see Doctor to get his account of the events so far.
==Walkthrough==
=== Central Pripyat ===
Doctor tells us about the rumors he's heard of Murzo and Recluse - and that the former is simply a pawn of the latter.
In terms of the recent developments, he saw Monolith fighters transferring a prisoner over to the Last Day soldiers, who have set up bases in both Zaton and Jupiter. We have to find this prisoner, who is likely being held in the workshops in the southwest of Zaton, in Journalistic investigation. The mysterious radio signal you heard after talking to Sakharov will sound off again...
=== Jupiter ===
The clues the journalist gave us lead to Jupiter. Last Day soldiers are stationed at the Volkhov AA facility and Elsa is imprisoned in the cell where Cartographer's loot was in Mystery of the islands. After wiping the area, speak to her to open The Golden Key - apparently a "pile of iron containers" was mentioned, likely referencing the cargo lot in the southwest corner of the area. Strelok will radio Voronin to send a helicopter to pick up Elsa once she is freed.
After completing The Golden Key, Elsa is rescued for good and the quest is marked as complete.
==Notes==
* A teleport at the bottom of the Volkhov AA facility prevents you from accessing the cell from below.
