Assassin's Creed Valhalla is a massive game that can have an overwhelming amount of activities to do. Finding something like a secret room can be annoying and ignoring it can have dire consequences during Assassin's Creed Valhalla's campaign. When it comes to opening Alfred's study room, there's only a certain way to do this. Players need to plan ahead and get their resources in order before making an attempt.
Toward the end of the campaign, players will have a conversation with Alfred one more time. During the talk, he will mention a secret study room that's hidden away within the land. He won't detail specifically where it is because players need to find out for themselves. There's a special key needed to open the door and players will need to venture out to find it. On top of that, finding the study room is also a little tricky if players don't follow the clues to solving challenges and puzzles.
When it comes to locked doors in Assassin's Creed Valhalla the first thing that obviously needs to be done is finding the key. The only way to do this is by completing "The Order of the Ancients Quest." Kill all the members except Hytham. What will happen is that he will give players a new mission that entails meeting up with the "Poor Fellow Soldier of Christ." During this mission, players will encounter Alfred and he will hand players a special key. Once the key is obtained, read the description engraved in it. It'll mention that the study room is tucked away somewhere in Wincestre.
Wincestre is a prime location in Assassin's Creed Valhalla where players can find a variety of optional missions, especially Assassin's Creed Valhalla romance. Once players make it to Wincestre, head over to the Old Minister and use Odin's Sight. Scan the area and look for a door that has a green aura fuming around it. That'll be the door that players will need to unlock. It's best to find a vantage point before using Odin's Sight so it can be located rather easily.
Once players get inside Alfred's study, they will find that it's a rather large room that has a slew of documents to read. It's encouraged to take the time to read the documents if players want a more fleshed out experience with the overall campaign. In this particular instance, these documents will explain Alfred's place with the Order of the Ancients and how he's tied into them. Plus, they'll also explain in more detail about Itsu and other situations which thickens the lore and fleshes out Assassin's Creed Valhalla's ending a little more.
Assassin's Creed Valhalla is available on Google Stadia, Microsoft Windows, PlayStation 4, PlayStation 5, Xbox One and Xbox Series X.
