Like a secret staircase behind a bookshelf? [He smiles.] Nothing like that yet, but I spend enough time in the library that I'd probably find one.
Everything here is free, so there are a few stores with basic things like food and clothes. And then if you ever need something specialty or specifically from home you can ask Acumen about it at the kiosk. It shows up on your map in the communicator if you press the top button.
You can also live in a room at the shelter or find yourself an empty apartment or house. There's still a lot of space. Helpful?
