Tool Dispensers are a type of vending machine encountered early in the course of BioShock 2. When these machines are activated, a Hack Dart drops into a receptacle for the player to grab. The purpose of these machines, gameplay-wise, is to provide the player with additional Hack Darts, should they run out before accomplishing the current Hacking task. Tool Dispensers cost no money to use, and it is recommended the player obtain their maximum number after the local Hacking activity.
