While the gameplay is very similar to that of "BioShock", some new features were added to the sequel. First, the player can use both plasmids (powers gotten from ADAM) and weapons at the same time. In addition, the player has a new weapon called the Hack Tool. This allows the player to hack machines from faraway by shooting Hack Darts at it. Instead of playing a Pipe Dream-like minigame every time the player hacks a machine, the player plays a timing-based minigame that happens as the game is still happening. The player can also use the Hack Tool to drop Mini-turrets. Instead of the wrench, the player's main melee weapon is the Drill. The Drill has a powerful drilling attack that can drain an enemy's health very quickly, but this attack will stop if the player runs out of Drill Fuel. The Drill also has a weaker melee attack that does not use Drill Fuel.
