A mod menu is a type of software modification that allows users to alter the behavior of a game or application. In the context of Granny 3, a mod menu can grant players access to unlimited resources, unlock special features, or even provide an unfair advantage over other players. These modifications are often created by third-party developers and can be downloaded and installed on a user's device.
