Stalker: Call of Pripyat → Quests → Oasis (where to find it)
In short, it’s complicated. After the game autosaves, exit to the Oasis, grab the artifact, and escape the wrath of the angry pseudo-dogs by going up the stairs. That’s it, you can go to the scientists and give them the artifact.
The place where the dotted line begins is the entrance to the ventilation shafts. There are a lot of jerboas there, but not many zombies. We enter the building, go “deeper,” turning left, and then the entrance to the shafts. After wandering through the tunnels for a bit, we come to a nondescript room, which is the last obstacle before finding the Oasis.
Personally, it’s quite difficult for me to describe the process of getting through this obstacle in words, because no matter how hard I tried, I couldn’t figure out the algorithm (and I didn’t even understand how I got through it). Here are some eyewitness comments:
…you need to run around the perimeter of this room, either clockwise or counterclockwise (I don’t remember which way I ran). After running around the entire room and passing through the “electric rain,” run again (along the perimeter, not straight ahead) to the second passage with the anomaly. You’ll be thrown back to the first exit, but another section of the room will light up. Run around the perimeter again, back through the passage. And do this three times, I think. Eventually, after another run like this, you’ll be able to go through that ill-fated corridor and reach the oasis (it’s located directly under the round thing, according to the map, but you can’t climb up there). © Ambi
