The storyline will tell you about "Labyrinth," an underground TerraGroup laboratory located beneath the "Lazurny Bereg" sanatorium.

To begin the storyline, you need to approach the entrance to Labyrinth (behind a door that can be unlocked with the key to the "OOO KNOSSOS" premises).

After waiting for approximately 36 hours, Jaeger will open a barter for the Labyrinth key card in exchange for 1 moonshine, 2 vodka, and 2 sausages. The barter is available 2 times per shipment. In return, he asks you to find out about a group of PMC BEAR fighters who stormed Labyrinth during evacuation. After successfully completing the operation, the group lost contact with command, and Labyrinth was closed.

At Labyrinth, you'll need to visit several points, picking up notes and finding the bodies of the group fighters. Additionally, to unlock room number 6 on the map, you'll need to retrieve a key from one of the lab assistants, marked on the map as number 2.

Exiting the Labyrinth, head to Shoreline and descend along the river to the drainage point near the Norvinsky yacht club. There, on the shore, you will find the Labyrinth research report.

All that's left is to come to Jaeger and hand over the tape. The old man will be upset, but he will reward you with 500,000 rubles, an AXMC rifle, two magazines, and 40 FMJ rounds.

Handing the tape over to Jaeger completes the "Labyrinth" storyline, and the player receives the "Theseus" achievement.
