Around midway through Frankie Fusilli's goals during his stay in the Penthouse, he will ask the player's sim to build a vault for the hotel. The Vault costs 3000 simoleons to build and is one of the most expensive rooms in the game. However, it only boosts your hotel score by 4% when built, which is joint least with the Secret Warehouse. The Vault is the only place in Strangetown to have The Goons as its default music, apart from when goons are invading certain areas.
Inside The Vault, it is fairly empty however there are a few unique objects that sims can interact with. These are listed below.
