Assassin’s Creed Valhalla Hidden Side Mission Guide: How to Open the Locked Door in Paris
In the Siege of Paris DLC for Assassin’s Creed Valhalla, there’s a hidden side mission that tasks you with finding three keys to unlock a special door. Completing this side mission rewards you with the Joyeuse Short Sword and an achievement. Here’s how you can complete it.
How to Open the Locked Door in Paris
To unlock the door in the Lutetia Bureau in Paris, you must first find three hidden keys scattered throughout Francia. Once you have all three, you’ll be able to access a locked door leading to the Assassin’s Bureau. The mission called Hidden will guide you to this location.
Hidden Key Locations
The three keys are located in different ruins across the map. Here are the locations you need to visit to find the keys:
- Champlieu Ruins
- Diodurum Ruins
- Gisacum Ruins
At each ruin, you’ll find a marked Assassin door. Enter the door to find a room where the key is hidden. Grab each key and add it to your inventory.
What’s Inside the Assassin’s Bureau
Once you’ve collected all three keys, head back to the locked door in the Lutetia Bureau. Open the door to earn the Future Past trophy/achievement and discover the Joyeuse Short Sword hidden inside. After claiming the sword, exit the bureau to find a special letter. This marks the end of the mission.
