This key allows you to explore new places and find more ways to advance in the game.

As you approach the Guard House, you'll see that the door needs a key. Head left down the alley beside the Guard House door.

This trail passes small storage areas that serve as great spots to duck out of sight.

A guard patrols the area and will soon pass by the storage zones, so watch out.

Now's the time to stay hidden, knock him out without making a sound, and get rid of his body so no one suspects anything.

Head forward until you encounter another guard next to a gate with a wire fence. Stick to the walls to stay out of view and sneak up behind him.

Once he's out of the way, head back to the Guard House and continue down the main path.

Look for a lit room on the left with the Bastione San Giovanni sign.

The next stop is this room, where a Blackshirt guard is inside the well-lit space.

Handle him quietly, then inspect the room to see if the Guard House Key is in it. Once the area is clear, it will be visible hanging on a noticeboard or wall.

Now that you have the key return to the Guard House door and unlock it. Some exciting rewards are waiting for you inside.

The first level of the Guard House contains items like a collectible letter on the table and a weapon secretly stashed in a drawer.

However, the real perk is accessing routes on the upper floor.

Unlock the double doors and use the ladder to check out other areas of the castle.

These paths let you skip over tough spots and come at objectives from other angles.

The key is optional to complete this, but getting into the Guard House makes it more worthwhile.

It provides extra tools, shortcuts, and hidden gems for those looking to explore more.
