BioShock
Throughout the game, the player will interact with many kinds of machines. Some machines give you items, like vending machines and safes, and others are enemies that attack you, such as security cameras, robots, and turrets. The player can hack all of these machines, and doing so will make buying items cheaper and give you extra items. If the machines are enemies, the player can use electricity to stun machines and hack them. If the player succeeds, then these machines will help the player fight enemies. To hack machines, the player will need to solve a puzzle. The puzzle is about connecting pipes so that a liquid can go from one place to another. If the player fails the puzzle, either the player loses health or security robots will attack the player.
