If you are a NieR: Automata fan you might have enjoyed the new addition in Final Fantasy XIV raid list:: The Puppet's Bunker.
But while running around and killing big robots did you notice that you can actually see 2B's Room and even enter it?
While I don't want to spoil the fun too much, you can even find some elements of the story inside the room.
You can access the raid location without using the duty finder anytime. The entrance is in Kholusia (X: 35.5 Y: 18.2) and you can exit anytime you want inside of the bunker by interacting with one of the black boxes.
