Enter the abandoned hospital then make your way to the lower section of the building. Afterward, look for a small cabinet near the area where Eleazar patients were previously treated. Interact with it to collect the Ancient Key.
Once you have the key, go deeper into the abandoned hospital until you come across a locked room. This is where you’ll use the Ancient Key.
Inside, you will find investigation points as well as lore notes. Opening the room will also grant you the hidden Before My Time achievement.
Final Thoughts
While the rewards are relatively small, the locked room is still worth visiting if you want to hidden achievement and learn more about the Eleazar storyline. It’s also a must-visit if you’re a completionist.
Overall, it’s a short but worthwhile side quest that most players accidentally skip during the Archon quest.
