In Fortnite's New Sanctuary map, there's a blue door. To open the blue door, you need to interact with it by pressing the corresponding key on your keyboard or controller.
Here's a step-by-step guide:
1. Find the blue door in New Sanctuary. You can search the map to locate it.
2. Approach the blue door and interact with it by pressing the 'Interact' key, which is usually the 'E' key on PC or the 'Square' button on console.
3. If you've interacted with the door correctly, it should open, and you might find some loot or items inside.
Please note that the blue door's location and purpose in the New Sanctuary map may change with each update or season, so make sure you're playing the most recent version of Fortnite.
