Menus and advancement systems in GD contain a number of hidden areas that are dispersed throughout the game. These regions are not merely for esthetic purposes; rather, they may have additional challenges, personalities, awards, and hints.
The Vault is one of the examples that is perhaps the most commonly recognized. Players are able to gain access to it once they have satisfied the necessary criterion, and subsequent interaction with the Goalkeeper can be achieved by entering specific codes. There are certain combinations that disclose icons or other surprises, giving players the opportunity to experiment outside the scope of the typical gameplay.
The Vault of Secrets is an expansion on this concept, as it contains its own collection of secrets and information that may be unlocked separately. It may feel like you are solving a minor puzzle that is buried deep within the bigger game when you first find these regions.
