If you're looking to complete your trophies in Last of Us 2, then you're going to have to locate yourself the Strange Artifact! We have a quick guide on exactly where you need to go to find it, so you won't be searching through the infected crawling lands for too long.
Locating the Strange Artifact Guide
The first piece of this puzzle is that you need to be in the following chapter: Seattle Day 1 - Hostile Territory. Now, look for a bunch of brick buildings in the Chinatown area of the map. You'll see one building labeled as the Jasmine Bakery (which has a safe in it, check out our guide for all the safe combinations). Keep running down the street until you see a red sign labeled with the name Ruby Dragon. Go inside of this building run to the back and then right through the door. Go up the stairs, once you're up them turn around and run down the hall that flanks the stairs. At the end of them you'll see a doorway with tables blocking it. Crawl underneath the tables and into this room. There's enemies in here, so take them out however you want.
There should be a large doorway that's open that leads out to the road. Go out there and jump across to the roof landing. Go to the left and through the open doorway. Go into that room and through another door and turn right. There's a table with a fan on it and the strange artifact you are looking to find! Pick it up and put it away to get the achievement!
