 The player can protect their vault in a number of ways, such as building walls, keeping guard dogs, setting up traps such as electrified floors and bottomless pits, and giving guns to the player's family members so that they can defend the vault as well.The game does not punish the player for family members—by default, a wife and two children—being murdered by intruders; the player can even view footage of the incident afterwards.Rather, protecting the money is the goal the game emphasizes.
