Question: What were the prototype Big Daddy characters called in the sequel version of the BioShock series?

 Assuming control of Subject Delta, a hulking Big Daddy, players are tasked with fighting through "splicers", the psychotic human population of the city, using weapons and an array of genetic modifications. BioShock 2 is a first-person shooter video game developed by 2K Marin and published by 2K Games.  It is the sequel to the 2007 video game "BioShock" and was released worldwide for Microsoft Windows, the PlayStation 3, and the Xbox 360 on February 9, 2010.  Feral Interactive released an OS X version of the game on March 30, 2012.  Set in the fictional underwater dystopian city of Rapture, the game's story takes place eight years after the events of the first "BioShock".  The game also introduces a story-driven multiplayer mode called "Fall of Rapture", which takes place during Rapture's 1959 civil war, before the events of the first game. <SEP> A Big Daddy is a fictional character in the "BioShock" series of video games.  Big Daddies are heavily spliced (genetically mutated and altered with ADAM) human beings who have had their bodies directly grafted into heavily armored, steampunk-inspired atmospheric diving suits.  They are armed with a rivet gun, heavy drill, rocket launcher, or ion laser.  Alpha series Big Daddies are equipped with any of several other weapons as well.  Though they make low-pitched groaning noises similar to whales, Big Daddies have no voice actor attributed to them.  Designed by Irrational Games (then under the supervision of 2K Boston/2K Australia), they first appeared in "BioShock" and were promoted heavily.  A six-inch Big Daddy action figure was included in the limited edition version of the title.  In its sequel, "BioShock 2", the player controls a prototype Big Daddy. <SEP> The "BioShock" series is a collection of story-driven first person shooters in which the player explores dystopian settings created by Ken Levine and his team at Irrational Games.  The first two games, "BioShock" and its direct sequel, "BioShock 2", take place in the underwater city of Rapture in the 1950s and 1960s, which was influenced heavily by Ayn Rand's Objectivism.  The third installment, "BioShock Infinite", is set aboard the floating air-city of Columbia in 1912, designed around the concept of American Exceptionalism.  Though "Infinite" is not a direct sequel to the previous games, the game is thematically linked; a short scene within the core "Infinite" game returns to Rapture, while the downloadable content "" tie in many of the plot elements between "BioShock" and "BioShock Infinite". <SEP> Veteranz Day is the seventh and final studio album by emcee Big Daddy Kane, released on April 28, 1998.  The album came four years after his previous effort, 1994's "Daddy's Home".  "Veteranz Day" received little attention, commercially and critically, and was met with mixed reviews and little sales.  It was his first and only album not to chart on the "Billboard" 200.  "Veteranz' Day" was the first and only album release for the small New York-based record label called the Label Records, which was founded by Frank Yandolino.  Although it managed to earn a distribution deal with Mercury Records by way of Joan Jett's and Kenny Laguna's Blackheart Records, which was acting as a boutique distribution outlet for independent labels from 1998 to 2000, The Label folded almost shortly after the release of "Veteranz Day".  The album features the single "Uncut, Pure," which reached the top 10 on the Hot Rap Singles chart.  There are two versions of "Uncut, Pure"—the original version produced by Easy Mo Bee, and a sequel version produced by Big Daddy Kane himself, the latter of which was released on the independently released 12-inch single and also featured as a bonus track on the CD and cassette versions of the album.
