one of the Little Sisters, Jack takes them back to the surface with him and adopts five of them as his daughters. Tenenbaum happily narrates how they go on to live full lives under his care, eventually surrounding him on his deathbed. This ending is considered canon in BioShock Infinite: Burial at Sea. If the player harvests more than one Little Sister, Jack turns on the Little Sisters to harvest their ADAM. Tenenbaum sadly narrates what occurs, condemning Jack and his actions. A US Navy submarine then comes across the plane's wreckage and finds itself suddenly surrounded by bathyspheres containing Splicers, who attack the crew and take control of it. The submarine is revealed to be carrying nuclear missiles, with Tenenbaum claiming that Jack has now "stolen the terrible secrets of the world": The more Little Sisters Jack harvests throughout the game, the harsher and more furious Tenenbaum's narrative becomes. Gameplay BioShock is a first-person shooter with role-playing game customization and stealth elements, and is similar to System Shock 2. The player takes the role of Jack as he is guided through Rapture towards various objectives. The player collects multiple weapons and plasmids as they work their way through enemy forces. The player can switch between one active weapon and one active plasmid at any time, allowing them to find combination attacks that can be effective against certain enemies, such as first shocking a Splicer then striking them down with a wrench. Weapons are limited by ammunition that the player collects; many weapons have secondary ammo types that can be used instead for additional benefits, such as bullets that inflict fire damage. Plasmid use consumes a serum called EVE which can be restored using EVE syringes collected by the player or by consuming cigarettes and alcohol. The player has a health meter that decreases when they take damage. The player can restore their health with food or medical packs found throughout Rapture. If the player's health reduces to zero, they will be regenerated at the last Vita-Chamber that they passed with limited amounts of health and EVE. A patch for the game allows players to disable these Vita-Chambers, requiring players to restart a saved game if the character dies. The game provides several options for players to face challenges. In addition to direct combat, the player can use plasmids to lure enemies into traps or to turn enemies against each
