Stopping it within the green area progresses the sequence and or potentially ends it while stopping in the blue area (this only needs to be done once per hack) may grant a bonus to the hacking attempt landing in a white area shocks the player (dealing a small amount of damage) while landing in red-colored areas can lead to the start of a security alert. This requires the player to stop a quickly-moving needle one or more times in the correctly-colored marked area of a gauge. The player will also encounter security systems which can be hacked through a mini-game. Money can be used to purchase more items at vending machines across the city. If the player is killed, they are revived in the nearest "Vita-Chamber".Īs the player explores Rapture, they will collect ammo, health and EVE (a liquid used to power Plasmid use) recovery items, and money. Unlike the first game, the player is able to equip both one weapon and one Plasmid at the same time, which they can use in quick succession to destroy foes for example, by first freezing a foe, they can be shattered into pieces using a spear gun. The player can use each weapon in a close-range melee attack. Several of the weapons in BioShock 2 are those that were previously seen carried by Big Daddies from the first game, including a powerful drill and a rivet gun. For example, Plasmids can give the player the ability to use telekinesis or evoke fire, while Tonics can improve the player's movement speed, attack damage, or damage resistance.
Plasmids and Tonics are special genetic-reencoding liquids that grant the user active or passive abilities, respectively, and include both those introduced in BioShock and new ones for this game. As with BioShock, the player explores Rapture and fights off Splicers, the remaining psychotic human population of the city, using a combination of the environment, weapons, Plasmids and Tonics. BioShock 2 is presented as a first person shooter with the player taking on the role of Subject Delta, a prototype for the Big Daddies approximately 10 years after the events of the first game.
