Stalker: Call of Pripyat → Path to Pripyat
The guide doesn't know the way to Pripyat and sends us to the Jupiter plant to get documents. We enter the plant through the main entrance, turn right, and enter the administrative building. In a room on the third floor, we find a folder with an order. The documents found in the administrative workshop speak of the evacuation of the production complex from the plant grounds. Information on this should be sought in the laboratory building.
There's a corridor leading to another building on the third floor. After that, turn left and find a notebook sheet on a shelf that mentions a certain item #62. Judging by the recording from the lab floor, the delivery department was supposed to be the one conducting the evacuation. We need to check this place.
We exit the building and move further away from the entrance. In the next building, on the first floor, there will be a sheet with the delivery details for this very same product. Now we head to the repair shop. We go around the main building and enter through the southern gate, descend into small underground corridors, and exit into the main building. There will be two Chernobyl dogs there. On the table, we find another document telling us to go to the first department, where we find evidence that an underground route to Pripyat exists.
The chemical compound shop should have information about the preservation of the Pripyat-1 underground overpass using some kind of gas. So we return the same way we came to the repair shop. Those who haven't yet tired of running around the abandoned plant looking for the document continue on.
The entrance to the underground overpass is behind the transport lock. We need to check this place and look for any information about the overpass. Finally, once we've collected all the documents, we go to technician Azot on Yanov Street, where he'll tell us about the underground passage to Pripyat .
Tips: Before leaving the factory, go to the third floor of the administrative building to pick up some more documents. They contain purely administrative information, but they're guarded by mercenaries, whose leader has some interesting information on his PDA. Take all the documents you find to the Duty leader; you can earn the "Information Trader" achievement. Bring the administrative information to the scientists' camp. You'll get 7,000 rubles + some medicine for it, and 2,500 rubles for Black's PDA.
